Geometry primitives in NYC State Plane (EPSG:2263)
NYC's empirical flood layers (Sandy, DEP, Ida HWMs) are published in EPSG:2263 (US survey feet). Reprojecting on every spatial query is wasteful, so the convention here is: load once, reproject to 2263 at ingest, do all distance/buffer math in feet. WGS84 is reserved for inputs (lat/lon from the geocoder) and outputs (GeoJSON for the map).3d53b81
