What to build

Implement the concession data cleaning module in tools/rustgis to ingest, reproject, and normalize oil palm (ATR/BPN HGU), timber/pulpwood (KLHK PBPH-HTI), and conservation boundaries into a unified schema.

Technical specifications

  1. Target files:
    • tools/rustgis/src/concessions.rs: Ingestion and attribute normalization module.
  2. Attributes schema:
    • company_name: Normalized uppercase company name.
    • concession_type: HGU_SAWIT | PBPH_HTI | PBPH_HA | KONSERVASI.
    • permit_id: Standardized decree/SK number.
    • group_name: Parent conglomerate name.
    • area_ha: Calculated geometry area in hectares.

Acceptance criteria

  • Cleans raw polygons with GEOS make_valid and reprojects to WGS84.
  • Normalizes attribute keys into uniform JSON schema.
  • Strips redundant metadata to minimize tile payload size.

Blocked by

  • Issue 20: [Backend] Geometry validation & GEOS topology repair (rustgis clean).
