Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.
Building footprints represent the perimeter extent of buildings.
Use of the data is for analytic and cartographic purposes.
The buildings data was collected using the following capture rules: Collect all buildings >500 sq. feet and taller than 12 feet. Buildings with <12 feet height but with BIN should be captured. Buildings with BIN but <500 sq. feet will be captured. Buildings with flat roofs will be captured on roof outline, capturing the largest outline (excluding overhangs, awnings, construction features, etc.). Buildings with pitched roofs will be captured on the building footprint. Carports, when attached to main building, will be included in the outline. Do not collect interior divisions (use existing building layer and BIN as guide). Do not collect temporary trailers, tents, or roofs at gas stations (over pumps). Use parcel data and BIN as guidance for collection. Where the parcel data indicates that a building should be two or more geometries AND there is NO physical indication, split the building using the parcel lines. Where the parcel data indicates that a building should be two or more geometries AND there is a physical indication, split the building using the physical indications. In cases where geometry previously existed in the legacy data, populate all resulting geometries with the original BIN (BINs will be duplicated in these cases). Do NOT collect roofs (overhang) to gas stations, unless connected to building. Do NOT collect movable jet bridge for access to aircraft. Do NOT collect awnings, scaffolds, or sidewalk sheds. Collect all garages, regardless of size, that can be identified as such, and driveways (paved or unpaved) that store one or more cars. Special care should be applied to ensure sheds are not to be confused with garages. Oftentimes, driveways do lead to sheds, so not all structures at a terminating driveway are considered to be garages. Sheds are not to be captured. Use Parcel layer to place garages within parcel or at parcel boundary check for special cases where parcel boundary clearly crosses garage. In these cases, either split the garage using physical features, or use the property line where there is no distinguishing physical feature. Do NOT collect small tool or storage sheds in backyards which have no visible car access. In cases where there is no BIN for the garage, a dummy BIN (1000000, 2000000, etc. for each of the Boroughs, see LION manuals pdf) will be populated.

All the NYCMap data was aerotriangulated and stereo-compiled to meet ASPRS Class 1 horizontal mapping standards and ASPRS vertical Class 2 accuracy specifications. The mapping standards deal with Root Mean Square (RMS) calculations that states if a random number of clearly identifiable surveyed ground control points throughout the project were compared to the mapped features, the RMS of the points would not exceed 2'. In layman's terms, 95% of the data is accurate to +/- 2'. Estimated accuracy: 95% of the data is accurate to +/- 2 feet How this value was determined: 95% of the data is accurate to +/- 2 feet

Building Height is calculated as the difference from the building elevation from the Elevation point feature class and the elevation in the interpolated TIN model. This value then is the height of the roof above the ground elevation, NOT its height above sea level.
