Building Outlines

The original building outlines were created from the 2005 Pictometry aerial imagery. The Building Class field was added from the 2011 Community Basemap project and the type 'apartment' was added to that domain in 2011. New building outlines were acquired from the 2011-2012 Pictometry flight and replaced the whole layer joining previous attribute information where possible. Building outlines and change analysis were completed again with the Pictometry flight in 2014. Building outlines and change analysis were completed with the Pictometry flight in 2016. Building outlines and change analysis were completed with the Pictometry flight in 2018. Building outlines and change analysis were completed with the Pictometry flight in 2020, and since then yearly updates have been sourced from Nearmap's AI model.

The latest building outlines were created from the February 2025 Nearmap image capture using the Nearmap AI model. Change detection is no longer captured nor are decks. The layer's schema was changed to mirror the new capture method.

Building classifications are 1=General/Residential, 2=Government, 3=Medical, 4=Education, 5=Transportation, 6=Commercial, 7=Religious, 8=Recreation, 9=Cultural/Heritage, 10=Hospitality, 11=Airport, 12=Industrial, 13=CommunityCenter, 14=Apartment
