1. Overview2. Data sources3. Reference period4. Target populationFor the purpose of exploring open data for official statistics and to support geospatial research across various domains, work was undertaken to create an accessible and harmonized database of building footprints released as open data by various levels of government within CanadaFootnote 1. This document details the process of collecting, compiling...
Multiple data sources were used to create the ODB. The data providers, which include municipal, regional, and provincial levels of government, are shown in Table 1. Attribution to each of these data sources is listed, as per the license requirements, in Appendix A. Where applicable, license versions are also shown. For further information on the in...
Ideally, the reference period would be the period from which the underlying building data refers to. Such information, however, was usually not available from the open data portals. In lieu of this, Appendix A provides the date each municipal dataset used in the ODB was downloaded. Data were gathered between January 2018 and August 2018 from open d...
The goal of the ODB is to create a centralised and harmonized repository of building footprints available from government open data sources across Canada. Emphasis was placed on compiling buildings where substantial activity (e.g., economic activity) may occur. For this reason, footprints smaller than 10m2 were removed as they were deemed too small...
Individual building datasets were downloaded from their respective government open data portals. Within the 65 datasets obtained, each data provider attached a different set of variables to the building footprints. Only variables common across all data sources were included in the final output. Prior to merging, datasets were standardised and clean...
All building footprints in the ODB were collected from government sources of open data. In general, other than the processing required to harmonize the different sources into one database, the underlying datasets obtained from the various open data portals were taken "as-is". Users are advised that the individual methodologies used, as well as the ...
