Quick Start
Instead of downloading and importing raw TIGER/Line shapefiles, restore a pre-built dump:
# 1. Download the dump (from releases)
wget https://git.supported.systems/mctiger/mctiger-data/releases/download/v2024.1/idaho-tiger-2024.dump
# 2. Restore to your PostGIS database
pg_restore -h localhost -U postgres -d tiger_geocoder idaho-tiger-2024.dump
What's Included
Each dump contains:
- tiger_edges - Road segments with geometries, names, address ranges
- tiger_featnames - Alternate road names and aliases
- tiger_places - City/town boundaries with pre-computed centroids
- Indexes - GiST spatial indexes and GIN trigram indexes (ready to query)
Creating Your Own Dumps
To create a dump for another state:
# 1. Download TIGER/Line data
tiger-download --state 06 # California
# 2. Import into PostGIS
tiger-import --state 06
# 3. Create dump
pg_dump -Fc -h localhost -U postgres tiger_geocoder > california-tiger-2024.dump
Versioning
Dumps follow the pattern: {state}-tiger-{year}.dump
- Year matches the TIGER/Line vintage (e.g., 2024)
- New releases are created when Census Bureau publishes updated data (typically annually)
