This data represents footprints of buildings within Strathcona County. Buildings greater than 400 square feet were identified and roof corners were captured to create a polygon. These footprints, along with elevation values, were captured using DAT/EM Summit Software.
Additional attributes provided include:
Building heights (using max z of roof corner elevation and average elevation below footprint)
Data was updated in 2016 with building footprints derived from the 2015 orthophoto imagery flown in May/June 2015.
