Houston Redlining Map

I created this with the Click2shp tool (, making my best informed assumptions about how to translate the HOLC map ( from 1930 to today's Houston. Then I used the SHP to GEOJSON converter ( to compile all of these into the geojson object in this repo.

I would welcome any corrections the community has to offer. While I have done my best to learn more about Houston history to understand the street name changes and neighborhood history, I imagine I made some mistakes.

As I mentioned on, this geojson file is free for non-commercial public use, though I would very much appreciate it if you would email me at and let me know what applications you have found for it.

You can’t perform that action at this time.
