Digital planimetrics are derived using the imagery products delivered with the 2022 New York Statewide Flyover (see Summary for specific flight dates), which includes raw imagery collected to support the generation of 0.5 Ft Ground Sample Distance (GSD) natural color imagery. The images were captured with 80% forward lap and side lap to support 1”=100’ mapping and meet the distortion free requirements within New York City. Planimetrics are developed to meet American Society for Photogrammetry and Remote Sensing (ASPRS) Class 1 (one) horizontal mapping standards and ASPRS vertical Class 2 (two) accuracy specifications. Planimetrics are delivered via an ESRI file geodatabase in New York State Plane Coordinate System, Long Island East Zone, NAD83, US foot (EPSG: 2263).
