detection methods

Initial Realignment

mtaip lessons learned
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
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.

webbas

Currently, the annual Boundary and Annexation Survey (BAS) is conducted in a paper format

  • WebBAS permits local governments to update TIGER governmental unit boundaries over the web
  • Work on prototype to continue in FY 04
  • OpenGIS Consortium (OGC) compliant
  • Integrates geospatial and form data to allow web-based alternative for respondents
