Infrastructure Service & Layer Styling

infrastructureService.js loads and normalizes layer data by current bounds, with per-layer fetching logic and field normalization. Styling is computed by getLayerStyle() using icon metadata and enhanced rendering flags.

Fetching & normalization​

  • Builds SoQL queries with within_box/intersects per layer; handles ArcGIS FeatureServer envelopes and JSON endpoints.
  • Normalizes fields for signs, meters, restrooms, etc., and converts EPSG:2263 coordinates to WGS84 where needed.
  • For DCWP garages, fetches footprint polygons by BIN in chunks.

Styling​

  • Returns MapLibre layer definitions per layer id (symbol/circle/line/fill) with size and color logic; integrates enhanced sprites when available.
