The Basics

  • Redistricting Maps for Texas counties made available by the U.S. Census Bureau (Census 2000).
  • TIGER/Line 2011 Files (Census Geography). These files contain the boundaries of the blocks, tracts, and other features needed to map census data in a Geographic Information System or mapping software.

GIS Layers:

  • Digital Data from the Texas Natural Resources Information System (TNRIS). TNRIS has many products including TxDOT map files for each county, ortho imagery, digital maps, and more.
