This API provides building data for the City of Montreal. The data was prepared by
Hochschule für Technik Stuttgart for
OGC Testbed-18.
Data Sources:
–
Bâtiments 3D 2016, Ville de Montréal (detailed building geometries for six arrondissements)
–
Building Footprints, National Resources Canada (extruded building footprints using the building height for all other arrondissements)
–
Unités d'évaluation foncière, Ville de Montréal (building function, year of construction, building category)
Sample requests:
– 500 buildings in Hampstead (
HTML,
glTF-Binary,
CityJSON)
– Buildings in a small bounding box around Percival Molson Stadium (
HTML,
glTF-Binary,
CityJSON)
– Buildings higher than 150 meters in Ville-Marie (
HTML,
glTF-Binary,
CityJSON)
– Buildings in Ville-Marie build before 1870 (
HTML,
glTF-Binary,
CityJSON)
– Notre-Dame (
HTML,
glTF-Binary,
CityJSON)
– A single building feature in the dataset, that is a church and an office building (
HTML,
glTF-Binary,
CityJSON)
– The dataset as 3D Tiles (
HTML using Cesium JS,
Tileset JSON)
– The dataset as Mapbox Vector Tiles (
HTML using MapLibre GL JS,
TileJSON)
Notes:
– The API has not been optimized for query performance.
– Most geometries have issues, for example, the polygons are often not planar.
– The CityJSON data in the links above is in the compound coordinate reference system
NAD83(CSRS)/UTM zone 18N + CGVD2013 height (
EPSG:6661), not the native CRS of the dataset
NAD83(CSRS)/MTM zone 8 + CGVD28 height (a compound CRS of
EPSG:2950 and
EPSG:5713), because CityJSON and OGC API Features both require a pre-defined compound EPSG or OGC CRS.
This API is developed as part of
OGC Testbed-18. The API is a work-in-progress and subject to change.
