Layer: ELEVATION (ID:6)

View In: Map Viewer

Name: ELEVATION

Display Field: STATUS

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description:

This feature class contains elevation points throughout the city of the following types:

BUILDING ELEVATION - Elevation of the highest portion of the roof of a building, excluding antennae and roof fixtures such as air conditioning (AC), elevator shafts, chimneys, etc.

WATER ELEVATION - Elevation on standing water (ponds, reservoirs, lakes).

SPOT ELEVATION –Elevation points collected in the center of the roadbed (coincident with CSCL), captured at beginning, mid-point, end, and at 200’spacing of the visible roadbed. Spot elevations are captured on paved, unpaved, alley subtypes in CSCL Centerline and all of Interior Sidewalk Centerline. Spot elevations will not be captured to a CSCL if no roadbed exists.

BRIDGE ELEVATION - Elevation points captured at beginning, mid-point, end, and at 200’spacing of the visible bridge deck.

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).

The Sanborn Map Company Inc. produced the data, and CARSI (Center for Advanced Analysis of Spatial Information) at Hunter College managed the project and conducted quality assurance for the data product.
