4) Converting/Export formats

  • GeoJSON — for web mapping and APIs.
  • CSV — for spreadsheets (include lat, lon columns).
  • Shapefile — legacy GIS compatibility (watch field name lengths).
  • PostGIS table — recommended for production use with spatial indexing.
  • MBTiles / vector tiles — for map rendering at scale.

Export tips:

  • When writing Shapefile, ensure field names ≤10 chars or use .dbf limitations.
  • For GeoJSON, keep coordinates as numbers and avoid null geometry entries.

2) Data validation checklist

  1. Verify CRS: ensure lat/lon in WGS84 (EPSG:4326).
  2. ID uniqueness: check for duplicate record_id.
  3. Coordinate validity: lat within [-90,90], lon within [-180,180].
  4. Country matching: coordinates should fall inside country polygon for country_code.
  5. Speed unit consistency: convert mph → km/h if dataset mixes units.
  6. Timestamp format: normalize to ISO 8601 (YYYY-MM-DD or full datetime).
  7. Schema completeness: flag missing critical fields (lat/lon, type, country).
  8. Source verification: ensure source_url reachable or documented.
  9. De-duplication: cluster points within small radius (e.g., 10 m) and reconcile duplicates.
  10. Privacy: remove any personal data (not expected in speedcam datasets).
