Summary
build_map_configso table CSVs attach to the matching tract vintage (not a single shared tract layer)explorer/config/sources.json(S3 map CSVs uploaded)Fixes #403
Why this broke
In May 2025 the explorer switched its only “US Tracts” layer from 2018 tiles to 2020 tiles (
use new 2020 tilesets for explorer).SDOH / Limited Mobility (
LimMobInd, etc.) and internet access (NoIntP) still use 2018-keyedHEROP_IDs (tract-sdoh-2014,tract-2019→geo-2018-tract). Those CSVs were then joined onto 2020 tract geometry, so roughly ~24% of tracts had no match and looked blank / “missing,” even though the data files were fine.build_map_configonly kept one explorer geodata source per summary level, so 2018 tract geography could not appear on the map at all.What this PR does
explorer_configback ongeo-2018-tract(tilesherop-lab.0eeozlm3) as US Tracts (2018)sources.jsonand routes each table to the correct layerSelecting Limited Mobility / related SDOH should use Tracts (2018); 2020/2025 variables stay on Tracts (2020).
Test plan
MoudTyp/MetTmDr2) still works on Tracts (2020)
