1. Why am I experiencing problems converting the UA Census 2000 TIGER/Line using ESRI's TIGERTOOLS?
The ESRI ArcInfo Workstation command TIGERTOOL, which can also be run from the "Tiger to Coverage Wizard" in ArcToolBox, does not convert the UA Census 2000 version of the U. S. Census Bureau TIGER/Line files correctly. The converter does not read the new definitions for certain items in the Record Type A, Tgrxxxxx.rta and the Record Type S, Tgrxxxxx.rts tables that pertain to the UA Census 2000 TIGER/Line files. Refer to the ESRI Online Support Center for the solution.
2. I heard that the original version of the UA Census 2000 TIGER/Line Files were replaced. Why?
The Census Bureau identified an error with the 1990 Urban/Rural Indicator (field name UR90) appearing on Record Type S in some of the UA Census 2000 TIGER/Line files. In 1094 counties, the 1990 Urban/Rural Indicator overstated the extend of the 1990 urban classification; some polygons were classified as 1990 urban when they should have been 1990 rural. The 1990 UA codes, as well as the 2000 UA/UC codes, and the 2000 Urban/Rural indicators were correct.
On June 7, 2002, the Census Bureau replaced all the UA Census 2000 TIGER/Line files, including those TIGER/Line files that did not contain an error in the 1990 Urban/Rural Indicator. When unzipped, the replacement UA Census 2000 TIGER/Line files have a date in May 2002. The original UA Census 2000 TIGER/Line files, when unzipped, will have dates in March and April 2002.
3. I have been having problems with the compressed files that I download. I get an error message when I try to unzip the file. Please advise.
One of our quality checks is downloading the files and decompressing them. We have not found any problems. However, we have heard from several users who have had problems decompressing the files using WinZip. You should try using PKWARE's PKZIP instead. They offer a free trial download.
