Data Format

Our base data format is GeoJSON. This reads easily into many web applications as well as GIS software. Find out more about this standard format here geojson.org.

Geometry

Geographic projection id EPSG:4326 (WGS84).
GeometryCollection and MultiPolygon geometries are resolved to individual features.

Feature ID

Building Identifier. It can occur multiple times in order to relate building parts.
Original ids are used with a prefix.

Feature Attributes

Attribute	Description
name	building name i.e. Chrysler Building
type	type of building i.e. commerce, residence
partId	for complex buildings: id of a building's part
origId	original ID of the feature from source data
height	total building height - in meters
heightSrc	source type for height attribute, possible values are: unknown manual ai photogrammetry lidar
minHeight	height at which a building part starts vertically (floating) - in meters
levels	total building levels
minLevel	levels at which a building part starts vertically (floating)
color	dominant color of building facade named colors, rgb() or #hex values
material	dominant material name i.e. concrete, glass
shape	building shape if unusual i.e. sphere, pyramid
roofShape	roof shape i.e. skillion, flat, dome
roofHeight	roof height (included in total height) - in meters
roofLevels	roof levels (add to buildings levels)
roofColor	dominant roof color named colors, rgb() or #hex values
roofMaterial	dominant roof material name i.e. tiles
roofDirection	direction where a roof is facing - clockwise in degrees from north
roofAngle	inclination of roof faces - in degrees upwards from horizon
date	date on which the feature was last edited
