Congratulations ! Domain change/server change still keep my login with
my searches (I have many search criteria made/saved in the last 3
weeks). However, map export is still not working. I have to screenshot
and rectified on ArcGIS for the TAZ level to compare it with our TAZ.
When I checked CTPP TAZ delineation project file made in 2011 all TAZ
numbers are different. Can anyone help me to link data and map ? (I
have not started numbering my rectified TAZ map from screenshot, our
area has 393 TAZ in CTPP data set and our model has ~1000 TAZ )
