[DDI-ADG] FW: Survey Research tools

[Katherine McNeill-Harman]

Mary,

I'm not quite sure whether what we've already proposed covers all they 
discuss.  The Geographic Coverage/Bounding Box was supposed to be the link 
to FGDC.  I guess a main point is the DDI's ability to define a geographic 
area by either a) a constructed area (e.g. political or other boundary) or 
b) an arbitrarily-requested geographic area (point, line, user-defined 
polygon (like agricultural plot in their scenario)).

I guess maybe a question is how well we allowed for points or lines (not 
just polygons).  I can't seem to find that explicitly in the geography 
spreadsheet, but thought I remembered us discussing it.  Anyone remember?
