## Dataset Description
The following dataset contains the collection of buildings in the geojson format for the city of Montreal. The dataset is created by combining multiple open-source datasets provided from NRCAN and the Montreal city government.

## Data Sources
1. [Montreal Property Assesment Units](https://donnees.montreal.ca/dataset/unites-evaluation-fonciere)
2. [Montreal 3D Buildings (LOD2 model with textures)](https://donnees.montreal.ca/dataset/batiment-3d-2016-maquette-citygml-lod2-avec-textures2) 
3. [Montreal Aerial Lidar Dataset](https://donnees.montreal.ca/dataset/lidar-aerien-2015)
4. [NRCAN Building Footprints](https://open.canada.ca/data/en/dataset/7a5cda52-c7df-427f-9ced-26f19a8a64d6)
5. [Administrative boundaries of the agglomeration of Montréal (boroughs and related cities)](https://donnees.montreal.ca/dataset/limites-administratives-agglomeration)

## List of dataset changes
1. Removed redundant building footprint vertices
2. Removed duplicate buildings (condominium unit duplicates)
3. Append building's district - "ADMIN_BOUNDARY"
4. Append building centroid - "CENTROID"
5. Remove buildings with 9999 year of construction
6.
