Annual Deprivation Measure Mapped

UK Deprivation Annual Index

This project generates vector tiles for the UK Deprivation Annual Index at the Lower Layer Super Output Area (LSOA) level.

Data Sources

• Lower Layer Super Output Areas (December 2011) boundaries
• Annual Deprivation Index data

Processing Steps

1. Reproject LSOA boundary geometries to WGS84 with 6 decimal places precision
2. Run process.py to join the deprivation data to the LSOA boundaries
3. Generate vector tiles from the combined GeoJSON using tippecanoe:

counter=0
for file in output/*.geojson; do
    tippecanoe --output="${file%.geojson}.pmtiles" --generate-ids --force --no-feature-limit --no-tile-size-limit --detect-shared-borders --coalesce-fraction-as-needed --coalesce-densest-as-needed --coalesce-smallest-as-needed --coalesce --reorder --minimum-zoom=0 --maximum-zoom=16 "$file"
    echo "Processed file $counter"
    counter=$((counter+1))
done

Output

The final vector tileset is written to output/LSOA.pmtiles.
