What to build

Create the compilation script scripts/build-concessions-pmtiles.sh using tippecanoe to produce concessions.pmtiles with multi-zoom simplification limits and attribute preservation.

Technical specifications

  1. Target files:
    • scripts/build-concessions-pmtiles.sh: Tippecanoe compilation script.
  2. Tippecanoe parameters:
    • Zoom range: z5 to z14.
    • Flags: --coalesce-densest-as-needed, --detect-shared-borders, --hilbert.
    • Output: public/tiles/concessions.pmtiles.

Acceptance criteria

  • Compiles concessions.pmtiles cleanly with file size under 60 MB.
  • Passes pmtiles verify inspection.
  • All corporate attributes (company_name, concession_type) preserved at zoom >= 8.

Blocked by

  • Issue 35: [Backend] Corporate concession data cleaning & schema normalization (tools/rustgis).
