Initial Realignment


Mtaip lessons learned l.jpg

MTAIP Lessons Learned

  • Census Bureau requirements can be very different from State/Local/Tribal GIS files

    • Street centerline approach differs from cadastre-level geography

    • Local files may not follow Census Bureau definition of topology


Mtaip feedback to source providers l.jpg

MTAIP Feedback to source providers

The Census Bureau will offer a “local edition” TIGER/Line file that includes information about the data used to realign TIGER to local source providers.
