Quebec building reference system

The Quebec building reference system consists of a continuous layer, created from a bird's eye view and presented in the form of vector polygons. This work is part of the effort to provide Quebec with a rich and comprehensive database that brings together information related to the built environment. It is the result of collaborative work between the Center for Research in Geospatial Data and Intelligence at Laval University, the municipal sector, Natural Resources Canada and Quebec ministries and agencies. This data set integrates geometries from various partnerships and produced using artificial intelligence and automated extraction algorithms. The geographic coverage corresponds to the information available when it was published and will be extended according to the availability of new data. For changes since the previous release or for more details on the production techniques and source data used, consult the ** [attribute list] (https://diffusion.mern.gouv.qc.ca/diffusion/RGQ/Vectoriel/Theme/Local/ReferentielBati/Document/ListeAttributs_RefBati.pdf) . ## #Caractéristiques levels of completeness The quality of the geometric data may vary depending on the level of completeness (NC)\ * reached and could differ from the reality on the ground, both in terms of representation and in terms of authenticity. This release incorporates NC-0 and NC-1 data corresponding to the following descriptions: * NC-0: Raw vector geometries, from various sources, with no quality control performed; * NC-1: Geometries validated manually (adjustments, additions, deletions).\ * Each level of completeness (NC) characterizes the level of work of editing, validation, and descriptive content of the data set. Thematic information will be added to the data set.This third party metadata element was translated using an automated translation tool (Amazon Translate).**
