Illinois Geographies

README.md

Boundaries

• All census boundaries in the download use CBF (Cartographic Boundary Files).

  • Excludes major water bodies, which is crucial to Illinois (Lake Michigan)
  • CBF does not apply to CBSA
  • Read more: https://www.census.gov/geo/maps-data/data/tiger-cart-boundary.html

• These two errors are expected when you run make for the first time:

  • make: *** No rule to make target shp/il_legislative/PA_97-6_Senate_Districts.shp', needed by topo/il_senate.json'. Stop.
  • make: *** No rule to make target shp/il_legislative/PA_97-6_House_Districts.shp', needed by topo/il_house.json'. Stop.

• If you run into the above error(s), run make shp/il_legislative and then make again. (This roundabout is a result of odd file/folder naming of the IL legislative boundary files).
