PROBLEM
TIGERTOOL converts 1995 BBSP files to NAD27 instead of NAD83
Solution or Workaround
Conversion of 1995 BBSP files, using TIGERTOOL, creates coverages with a NAD27 datum when the PROJECT option is used, but the datum should be NAD83.Cause:
In version 7.0.4, the PROJECT command used by TIGERTOOL defaults to NAD27. All TIGER files previous to 1995 used the NAD27 datum. The BBSP TIGER/Line files called TIGER/Line Files, 1995 are exactly the same as the TIGER/Line '94 files, but they are now in NAD83 and not NAD27 - except for Hawaii and the outlying territories.
