100 CLT UK Projects (ICPSR 194581)
Released/updated on: 2023-10-19
The study data was acquired from an industry report prepared by Waugh and Thistleton (2018) and funded by the Softwood Lumber Board & Forestry Innovation Investment. The report is entitled “100 UK CLT Projects” and showcased a wide array of CLT projects between the years 2005 and 2018. For each project, the following information is provided: general description of the project, schematic drawings, project renderings or real photos, abstract construction data, the project type, the project team, and the structure type. This study depended mainly on the project team composition data. The team of each project included a firm or more of the following stakeholders: architect, structural engineer, main contractor, timber engineer, timber contractor, and timber manufacturers. The report information was coded in a tabular format to capture the structure type and the collaborating team data for each project. First, a project data table was created to assign each project a unique identification number and provide the following data fields: structure type and the project team firms. It should be noted that some project teams involved multiple firms of the same stakeholder type, e.g. a large or complex project may involve multiple architects, engineers or main contractors. Second, the unique firm instances are filtered from the project records and assigned unique identification numbers. Third, a data matrix structure was created to relate each project (as rows) to the involved team stakeholder firm (as columns). There were a total of 261 project stakeholders involved in these projects, including: 73 architecture, 58 structural engineering, 74 main contracting, 31 timber engineering, 10 timber contracting, and 15 timber manufacturing companies. To perform the longitudinal analysis, the projects and their stakeholder firms were organized in four time periods.

10(j) Injunctions (ICPSR 226824)
Released/updated on: 2025-04-15
Time period: 2010-01-01--2025-01-01
Section 10(j) of the National Labor Relations Act authorizes the National Labor Relations Board to seek temporary injunctions against employers and unions in federal district courts to stop unfair labor practices while the case is being litigated before administrative law judges and the Board. These temporary injunctions are needed to protect the process of collective bargaining and employee rights under the Act, and to ensure that Board decisions will be meaningful. The section was added as part of a set of reforms to the Act in 1947. Over the years, all NLRB General Counsels have made use of this effective enforcement tool, as shown in this chart.There are 15 categories of labor disputes in which Section 10(j) injunctions may be appropriate, listed at [https://www.nlrb.gov/what-we-do/investigate-charges/10j-injunctions/section-10j-categories]. Under NLRB processes, potential cases are identified by Regional Offices and reviewed by the General Counsel, who must seek authorization from the Board before proceeding to court. The csv contains Authorization Dates, Case Numbers, Case Names, and Injunction Status as of the date collected (2025-04-07). This list is all 10(j) injunction cases authorized by the Board since September 1, 2010.

1968-98 Civil Rights Data Collection (ICPSR 219621)
Released/updated on: 2025-02-15
Time period: 1968-01-01--1998-01-01
The Civil Rights Data Collection (CRDC), formerly administered as the Elementary and Secondary School Civil Rights Survey, is an important part of the U.S. Department of Education's (Department) Office for Civil Rights (OCR) strategy for administering and enforcing civil rights laws in the nation’s public school districts and schools. The CRDC collects a variety of information including student access to rigorous courses, programs, resources, instructional and other school staff, and school climate factors such as student discipline and harassment and bullying. Much of the data is disaggregated by race/ethnicity, sex, disability and whether students are English Learners.Since the 2011–12 school year, OCR has collected data from all public districts and their schools in the 50 states and Washington, DC. Over time the CRDC’s collection universe has grown to include long-term secure justice facilities, charter schools, alternative schools, and special education schools that focus primarily on serving students with disabilities. OCR added the Commonwealth of Puerto Rico to the CRDC, beginning with the 2017-18 CRDC. From 1968 to 2010, civil rights data were collected from a sample of public districts and their schools, except for the 1976 and 2000 collections, which included data from all public schools and districts.The purpose of the CRDC Archival Download Tool (Archival Tool) is to make the Department’s civil rights data from 1968 to 1998 publicly available. The Archival Tool organizes civil rights data by year, and provides users with access to the data, survey forms, and other relevant documentation. The tool also includes documentation on key historical CRDC data changes from 1968 to 1998. Users may extract district-level civil rights data.
Important Consideration: Past collections and publicly released reports may contain some terms that readers may consider obsolete, offensive and/or inappropriate. As part of the Department’s goal to be open and transparent with the public, we are providing access to all civil rights data in its original format.Privacy notice:The Department of Education’s Disclosure Review Board determined that the CRDC files for 1968-1998 are safe for public “re-release” under the Family Educational Rights and Privacy Act (FERPA) (20 U.S.C. § 1232g; 34 CFR Part 99).

1973 Consolidated Development Directory, HUD (ICPSR 174641)
Released/updated on: 2022-07-07
Time period: 1936-01-01--1973-01-01
This data was manually entered from the Consolidated Development Directory (Report S-11A), published by the Department of Housing and Urban Development, Housing Production and Mortgage Credit, Statistical Operations Branch on June 30, 1973. It contains development information on all low-rent housing projects administered by FHA. The CDD was viewed on microfiche (506 pages), with page 372 missing and some entries blurry to varying degrees. Data was rarely too difficult to read, whenever possible blurry or incomplete numbers were filled to the best of our ability. US States and Washington DC was digitized – US territories were not. County in the digitized spreadsheet was also added manually. When a city spanned multiple county lines and was not specified in the original spreadsheet, projects were assigned to the city’s primary county. Counties for New York City and Kansas City, MO were simply classified as missing. This directory is issued annually and replaced the June 1972 issue of the Consolidated Development Directory (S-11A).

The 1990-2010 wildland-urban interface of the conterminous United States - geospatial data (2nd Edition) (ICPSR 249514)
Released/updated on: 2026-06-09
Time period: 1990-01-01--2010-01-01
The wildland-urban interface (WUI) is the area where houses meet or intermingle with undeveloped wildland vegetation. This makes the WUI a focal area for human-environment conflicts such as wildland fires, habitat fragmentation, invasive species, and biodiversity decline. Using geographic information systems (GIS), we integrated U.S. Census and USGS National Land Cover Data, to map the Federal Register definition of WUI (Federal Register 66:751, 2001) for the conterminous United States from 1990-2010. These data are useful within a GIS for mapping and analysis at national, state, and local levels. Data are available as a geodatabase and include information such as housing and population densities for 1990, 2000, and 2010; wildland vegetation percentages for 1992, 2001, and 2011; as well as WUI classes in 1990, 2000, and 2010.

1998-2023 Serotype Data for Invasive Pneumococcal Disease Cases by Age Group from Active Bacterial Core surveillance (ICPSR 243434)
Released/updated on: 2026-01-11
CDC monitors invasive bacterial infections that cause bloodstream infections, sepsis, and meningitis in persons living in the community through Active Bacterial Core surveillance (ABCs). ABCs conducts laboratory- and population-based surveillance for invasive pneumococcal disease (IPD). ABCs serotype data are used to measure the impact of vaccine use in the United States on vaccine-type IPD. This table reports IPD case counts in the ABCs catchment area by serotype for years 1998 through 2023. Cases are grouped into the following mutually exclusive age groups: age <2 years old, age 2–4 years old, age 5–17 years old, age 18–49 years old, age 50–64 years old, and age ≥65 years old. Cases are reported by ABCs surveillance site (noted as the 2-letter state abbreviation). Combined data for all ABCs sites are labeled as “All_Sites”. ABCs methods and surveillance areas reporting IPD cases have changed over time. Given these changes, trends in serotype distribution by year, age group, and site should be interpreted with caution. Analyze and visualize data using the ABCs Bact Facts Interactive Data Dashboard. Read less

19th century Hebrew Press Reuse Network (ICPSR 231662)
Released/updated on: 2025-06-01
Time period: 1856-01-01--1897-12-31
This dataset supports a study of textual reuse in the Hebrew-language press between 1856 and 1897—a period during which Jewish communities, dispersed across Europe, the Middle East, and the Americas, created a shared communicative infrastructure through Hebrew newspapers.The dataset includes approximately 130,000 articles drawn from 13 Hebrew-language periodicals, digitally processed and compared using a Hebrew-language plagiarism detection tool (Originality). It identifies over 300,000 instances of sentence-level reuse between articles, with metadata on source and target journals, the number of shared sentences, and time lags. Only reuse between Hebrew texts was analyzed; translations from non-Hebrew sources were excluded. By mapping these intertextual connections, the project reconstructs a transnational media network that functioned as a global Jewish “town square.” The data enables exploration of editorial behavior, thematic clustering, and the role of journalism in diasporic identity formation.

2001 Residential Financial Survey (ICPSR 218541)
Released/updated on: 2026-03-12
Time period: 1991-01-01--2001-01-01
The 2001 Residential Finance Survey (RFS) was sponsored by the Department of Housing and Urban Development (HUD) and conducted by the Census Bureau. The RFS is a follow-on survey to the 2000 decennial census designed to collect, process, and produce information about the financing of all nonfarm, residential properties. Previous RF surveys have been integral parts of the decennial censuses since 1950. Primary users of RFS data in addition to HUD include the Bureau of Economic Analysis, Fannie Mae and Freddie Mac, and the Congress. Data are collected, tabulated, and presented for properties, the standard unit of reference for financial transactions related to housing. In the RFS, a property is defined as all the buildings and land covered by a single first mortgage. The sample for the RFS is stratified by property size, with large properties overrepresented in the sample. Very large properties are selected with certainty to control their effect on the reliability of the estimates. The RFS is the only standardized single source of detailed information on property, mortgage, and financial characteristics for multiunit properties. Both property owners and mortgage lenders are interviewed, resulting in more accurate information on property and mortgage characteristics. As part of the decennial census, the RFS is mandatory. This is important in collecting information from mortgage lenders.

2003 National Immunization Survey (ICPSR 101387)
Released/updated on: 2025-08-08
Time period: 2003-01-01--2003-01-01
This survey is part of a series that was designed to track the rates of proper vaccination of children in the United States. The target age range for the children was 19 to 35 months. Respondents were queried on the number of children present in the household between the ages of 12 months and 3 years, their dates of birth, their sex, whether there were vaccination records for the children, whether those records were accessible, whether the respondent was the adult in the household most knowledgeable about the vaccinations, and whether the respondent accompanied the children to more than 50 percent of their vaccinations. For each child in the household, information was gathered on whether each child had received all of the recommended vaccinations, and the number of the diphtheria-tetanus-pertussis shots (DTP or DT), polio vaccinations, measles vaccinations, meningitis or Haemophilus Influenzae type B (HIB) shots, varicella (chicken pox) vaccinations, rotavirus shots, pneumococcal shots, and hepatitis B (Hep B) shots each child had received. Further information was obtained about additional vaccinations the child may have received to combat diseases such as tuberculosis, typhoid, yellow fever, and malaria, the child's health care providers, the number of doctors that had performed vaccinations, and whether the measles vaccination was strictly for measles or for the measles-mumps-rubella (MMR) combination. Additional information was gathered regarding whether the child received benefits from the nutrition and health program for Woman, Infants, and Children (WIC), what age the child began receiving WIC benefits, whether the child's vaccination records were checked at the WIC certification visit, and whether these benefits had ever been interrupted for six months or more. Once parental consent was obtained, health care providers were queried on the vaccination records for each child whose vaccination information was gathered from parents. Health care providers were queried on the type and the level of detail of the vaccination records for each child, the dates and types of vaccinations administered, the date of each child's first visit to that provider regardless of reason, the date of the child's most recent visit to that provider regardless of reason, and the type of care the provider gave to the child. Health care provider respondents were asked to describe their facility, to give their position within the facility, the child's date of birth, according to their records, and whether the child was known by another last name, and to provide a list of any additional health care providers for that child. Demographic information provided by the parents or guardians includes the number of people living in the household, the number of people over and under 18 in the household, respectively, the number of children under the age of 12 months, ethnicity of respondent and child, marital status of the respondent, respondent's relationship to the child, respondent's educational level or that of the child's mother, the date of birth of the child's mother, household income, and whether the child was living at the same address as when he or she was born.

2006 Ventenata dubia distribution in the Blue Mountains Ecoregion of Oregon, Washington, and Idaho - probability (ICPSR 249232)
Released/updated on: 2026-06-03
Time period: 2005-01-01--2007-01-01
This data publication contains two (2) georeferenced raster (GeoTIFF) files representing the 2006 probability and probability classes of Ventenata dubia (ventenata) presence throughout the Blue Mountains Ecoregion located within Oregon, Washington, and Idaho. The Blue Mountains Ecoregion is part of the Environmental Protection Agency (EPA) Level III Ecoregion classification (https://www.epa.gov/eco-research/ecoregions). Presence of ventenata in these data was defined based on field observations of aerial cover, where 20% and greater cover was classified as presence and less than 20% cover was classified as absence. Thus, the probability and probability classes of ventenata presence corresponds to populations with greater than or equal to 20% cover (not individual ventenata plants). Field observations were aggregated from sources including the United States Department of Agriculture (USDA), Forest Service; the Bureau of Land Management (BLM); and Oregon State University (OSU). Ventenata was mapped using the random forests classification method with land surface phenology, climate, soils, and terrain attributes. The 2006 prediction of ventenata was produced from a model trained from land surface phenology in 2017. To improve model transferability, 2006 was chosen based on climatic similarity as measured by a drought severity index and RAWs weather station data. The model was used to determine a probability threshold that is optimal for differentiating both presence and absence (Threshold = 0.58). This threshold was used to split the probability gradient into 6 classes, 2 classes below the threshold and 4 above.

2009-2013 5-Year American Community Survey: Commuting Flows (ICPSR 100616)
Released/updated on: 2025-08-08
Among other questions related to the work commute, the American Community Survey (ACS) asks respondents about their primary workplace location. Workplace information is crucial for understanding the degree of interconnectedness among our nation's communities and it shapes the contours of metropolitan and micropolitan statistical areas. The U.S. Census Bureau's publicly available ACS tables present information about where people work by both residence-based and workplace-based data products, but information about the residence/workplace relationship is not provided as an origin-destination combination. A more complex story about commuting patterns emerges when residence location and workplace location are coupled, generating a "commuting flow." This page provides commuting flow data from the decennial Census and ACS, some of which has been produced for the purpose of redefining metropolitan and micropolitan statistical areas.From https://www.census.gov/hhes/commuting/data/commutingflows.html as of March 29, 2017.This archive contains the files derived by the Census Bureau from the 2009-2013 5-year American Community Survey.

Released/updated on: 2019-11-21
To help data users understand how differential privacy may or may not impact data products they are used to receiving, the Census Bureau created demonstration data products for review. This set of data products demonstrate the current computational capabilities of the 2020 Disclosure Avoidance System (DAS). The products include the 2010 Demonstration Public Law 94-171 (P.L. 94-171) Redistricting Data Summary File and the Demographic and Housing Demonstration File. The files apply the DAS to the 2010 Census confidential data — that is, the unprotected data from the 2010 Census that are not available publicly. Note that the published 2010 Census data were protected using the traditional statistical disclosure avoidance procedures such as swapping and suppression.The Census Bureau encourages data users and data scientists to examine the products and provide feedback as they continue to develop and fine-tune disclosure avoidance systems. They are releasing these products to encourage independent analyses from the data user community and a robust, open, data-driven dialogue.

2010 Survey of U.S. Publicly Funded Family Planning Clinics (ICPSR 163961)
Released/updated on: 2022-03-31
Time period: 2010-01-01--2011-12-01
The Guttmacher Institute has a long history of studying U.S. publicly funded family planning clinics and conducting sample surveys to better understand and document the clinic network’s range of service delivery practices and the challenges it faces. These data are from a survey of a nationally representative sample of publicly funded family planning clinics conducted in 2010–2011 and are both an extension of earlier surveys and an investigation of new topic areas relevant to the provision of clinic services today. A total of 664 publicly funded family planning clinics in the U.S. provided information about the types of contraceptive methods and related services offered onsite and through referral; service delivery practices and protocols, particularly those that have the potential to affect service accessibility, method initiation and continuation, and care for patients with special needs; the types of outreach and special programs offered; protocols and technology used for screening and testing (including for cervical cancer and HIV); services for male partners and clients; service costs and financial challenges; and a variety of other aspects related to clinical practices and management.

The 2010 wildland-urban interface of the conterminous United States - geospatial data (1st Edition) (ICPSR 249632)
Released/updated on: 2026-06-09
The wildland-urban interface (WUI) is the area where houses meet or intermingle with undeveloped wildland vegetation. This makes the WUI a focal area for human-environment conflicts such as wildland fires, habitat fragmentation, invasive species, and biodiversity decline. Using geographic information systems (GIS), we integrated U.S. Census (2010) and USGS National Land Cover Data (2006), to map the Federal Register definition of WUI (Federal Register 66:751, 2001) for the conterminous United States. These data are useful within a GIS for mapping and analysis at national, state, and local levels.

2013 to 2016 Picture of Subsidized Housing Data (ICPSR 100906)
Released/updated on: 2026-03-09
Time period: 2013-01-01--2016-01-01
Since passage of the U.S. Housing Act of 1937, the federal government has provided housing assistance to low-income renters. Most of these housing subsidies were provided under programs administered by the U.S. Department of Housing and Urban Development (HUD) or predecessor agencies. All programs covered in this report provide subsidies that reduce rents for low-income tenants who meet program eligibility requirements. Generally, households pay rent equal to 30 percent of their incomes, after deductions, while the federal government pays the remainder of rent or rental costs. To qualify for a subsidy, an applicant’s income must initially fall below a certain income limit. These income limits are HUD-determined, location specific, and vary by household size. Applicants for housing assistance are usually placed on a waiting list until a subsidized unit becomes available.Assistance provided under HUD programs falls into three categories: public housing, tenant-based, and privately owned, project-based.In public housing, local housing agencies receive allocations of HUD funding to build, operate or make improvements to housing. The housing is owned by the local agencies. Public housing is a form of project-based subsidy because households may receive assistance only if they agree to live at a particular public housing project.Currently, tenant based assistance is the most prevalent form of housing assistance provided. Historically, tenant based assistance began with the Section 8 certificate and voucher programs, which were created in 1974 and 1983, respectively. These programs were replaced by the Housing Choice Voucher program, under legislation enacted in 1998. Tenant based programs allow participants to find and lease housing in the private market. Local public housing agencies (PHAs) and some state agencies serving as PHAs enter into contracts with HUD to administer the programs. The PHAs then enter into contracts with private landlords. The housing must meet housing quality standards and other program requirements. The subsidies are used to supplement the rent paid by low-income households. Under tenant-based programs, assisted households may move and take their subsidy with them. The primary difference between certificates and vouchers is that under certificates, there was a maximum rent which the unit may not exceed. By contrast, vouchers have no specific maximum rent; the low-income household must pay any excess over the payment standard, an amount that is determined locally and that is based on the Fair Market Rent. HUD calculates the Fair Market Rent based on the 40th percentile of the gross rents paid by recent movers for non-luxury units meeting certain quality standards.The third major type of HUD rental assistance is a collection of programs generally referred to as multifamily assisted, or, privately-owned, project-based housing. These types of housing assistance fall under a collection of programs created during the last four decades. What these programs have in common is that they provide rental housing that is owned by private landlords who enter into contracts with HUD in order to receive housing subsidies. The subsidies pay the difference between tenant rent and total rental costs. The subsidy arrangement is termed project-based because the assisted household may not take the subsidy and move to another location. The single largest project-based program was the Section 8 program, which was created in 1974. This program allowed for new construction and substantial rehabilitation that was delivered through a wide variety of financing mechanisms. An important variant of project-based Section 8 was the Loan Management Set Aside (LMSA) program, which was provided in projects financed under Federal Housing Administration (FHA) programs that were not originally intended to provide deep subsidy rental assistance. Projects receiving these LMSA “piggyback” subsidies were developed under the Section 236 program, the Section 221(d)(3) Below Market Interest Rate (BMIR) program, and others that were unassisted when originally developed.Picture of Subsidized Households does not cover other housing subsidy programs, such as those of the U.S. Department of Agriculture’s Rural Housing Service, unless they also receive subsidies referenced above. Other programs such as Indian Housing, HOME and Community Development Block Grants (CDBG) are also excluded.

This data set is created to allow researchers to analyze the 2015 Canadian Federal Election using the Dyad Ratios Algorithm on Wcalc software created by James Stimson (http://stimson.web.unc.edu/software/). (See for example Stimson, J. A. (1991). Public opinion in America: Moods, cycles, and swings (Vol. 12). Boulder, CO: Westview Press. Or Stimson, J. A. (2004). Tides of consent: How opinion movements shape American politics. Cambridge University Press.) The software Wcalc can be found here: http://stimson.web.unc.edu/software/. Each major political party in 2015 has a separate excel file containing the party's level of support in surveys. Data for the party support in polls was gathered from Wikipedia at https://en.wikipedia.org/wiki/Opinion_polling_in_the_Canadian_federal_election,_2015
Each file contains the date the survey was completed (month-day-year), the total sample size minus, percentage of the responses supporting the party in the table, and a recoded variable name. The recoded variable name corresponded with the survey firm and the question asked. The following firms are included in the datasets:
- Nanos
- Forum
- Leger
- Ipsos
- Innovative
- Angus
- Abacus
- EKOS
The excel sheets for each party support are saved as a text file. Wcalc was used to run a time series of the data. When creating the time series, daily was selected and smooth on raw data series. Wcalc produced an excel file with an average of the days, and a log file interpreting the results (see Wcalc files for the results). This was repeated for each party. The resulting CSV files show party support overtime and the log files show the Iteration History and the factor loadings.
Also included in this package is the code for the program R, which can also be used to run the Dyad Ratios Algorithm (see Extract.r.zip and ExtractDoc.pdf; Shared with permission of Dr. James Stimson).

Released/updated on: 2023-12-11
Time period: 2016-05-01--2017-06-01
Digital reading is ubiquitous, yet understanding digital reading processes and links to comprehension remain underdeveloped. Guided by New Literacies and Active Reading theories, this study explored the reading behaviors and comprehension of thirteen 5th graders who read static digital texts. We coded for the quantity and quality of digital reading behaviors and employed action path diagrams to connect behaviors to comprehension. We used timescape analyses to visualize how behaviors were orchestrated differently across readers. Findings showed no single behavior was related directly to comprehension, indicating varying pathways to digital reading success. Occasional re-reading seemed to support active reading and improved comprehension. Instances of students subverting expected digital tools were observed. Minor distractions like mind-wandering did not link to poor performance. This research deepens our understanding of self-monitoring and active reading in static digital contexts, offering insights for future study of more complex digital reading contexts like reading on the internet.

Since the 1980s, the Office of Refugee Resettlement[1] (ORR) has conducted the Annual Survey of Refugees (ASR), which collects information on refugees during their first five years after arrival in the U.S. The ASR is the only scientifically-collected source of national data on refugees’ progress toward self-sufficiency and integration. ORR uses the ASR results alongside other information sources to fulfill its Congressionally-mandated reporting following the Refugee Act of 1980. Historically, the microdata from these surveys have generally been unavailable to researchers. In the Spring of 2017 ORR completed its 50th Annual Survey of Refugees (ASR). The data from the ASR offer a window into respondents’ first five years in the United States and shows the progress that refugee families made towards learning English, participating in the workforce, and establishing permanent residence. This public use data deposit is only for the 2016 ASR with future years likely to be added to the ICPSR archive..

[1] The Office of Refugee Resettlement (ORR) at the Administration for Children and Families in the U.S. Department of Health and Human Services (HHS) serves refugees and other humanitarian entrants, including asylees, Cuban and Haitian entrants, Special Immigrant Visa holders, Amerasians, victims of human trafficking, and unaccompanied children. By providing these arrived populations with critical resources, ORR promotes their economic and social well-being. Of these populations, the Annual Survey of Refugees focuses solely on refugees who have come to the U.S. in the past five fiscal years.

2017 Ventenata dubia distribution in the Blue Mountains Ecoregion of Oregon, Washington, and Idaho - probability (ICPSR 249233)
Released/updated on: 2026-06-03
Time period: 2016-01-01--2018-01-01
This data publication contains two (2) georeferenced raster (GeoTIFF) files representing the 2017 probability and probability classes of Ventenata dubia (ventenata) presence throughout the Blue Mountains Ecoregion located within Oregon, Washington, and Idaho. The Blue Mountains Ecoregion is part of the Environmental Protection Agency (EPA) Level III Ecoregion classification (https://www.epa.gov/eco-research/ecoregions). Presence of ventenata in these data was defined based on field observations of aerial cover, where 20% and greater cover was classified as presence and less than 20% cover was classified as absence. Thus, the probability and probability classes of ventenata presence corresponds to populations with greater than or equal to 20% cover (not individual ventenata plants). Field observations were aggregated from sources including the United States Department of Agriculture (USDA), Forest Service; the Bureau of Land Management (BLM); and Oregon State University (OSU). Ventenata was mapped using the random forests classification method with land surface phenology, climate, soils, and terrain attributes. The model was used to determine a probability threshold that is optimal for differentiating both presence and absence (Threshold = 0.58). This threshold was used to split the probability gradient into 6 classes, 2 classes below the threshold and 4 above.
