PACI Kuwait Finder & TripleDES Token Architecture

  • • PACI ArcGIS VectorTileServer powers parcel boundary polygons and official Kuwait street networks
  • • LightNode Kuwait VPS (paci-kw) injects TripleDES signatures and API credentials, keeping client builds secure
  • • Kuwait Finder mobile deep links (https://gis.paci.gov.kw/?id=<UUID>) resolved deterministically via PACI search SOE

Baladia GIS & Kuwait Municipality Law 33/2016

  • • Direct integration with gismaps.baladia.gov.kw ParcelLocation_MKM spatial endpoint
  • • Automatic extraction of Floor Area Ratio (FAR): 210% residential, 250% investment, 300%+ commercial
  • • Validates municipality building license status and setbacks before generating appraisal certificates

PostGIS High-Performance Spatial Cache

  • • Supabase PostGIS paci_parcels table caches millions of Kuwait parcel polygon coordinates with GIST indexing
  • • High-performance RPC nearby_parcels(lat, lng, radius_meters) resolves GPS coordinates in under 15ms
  • • Blue metal plate (اللوحة الزرقاء) OCR converts field wall photos into official 8-digit PACI Civil Numbers
