Solution or Workaround
If a coverage is projected after running TIGERTOOL, why do the IDs get scrambled?
Answer:
Run IDEDIT on the cover1 with the poly option. For example, if the coverage created was county1, then IDEDIT would be run as follows:
idedit county1 poly
Re-project the coverage after running IDEDIT on the cover1 created by TIGERTOOL.
Notes:
Only cover1 is affected. IDEDIT does not have to be run on cover2 or cover3.
