Urban planning analysis using stereo mapping feature collection

Metro Vancouver is Canada's third most populated metropolitan region, with the prospect of reaching 4 million people in the mid-2040s, according to recently published population projections. Metro 2050, The Regional Growth Strategy, highlighted regional urban centres as the priority locations for services and amenities that support a growing population. The focus of the growth to urban centres means an essential change of centres' urban form towards higher density and their "vertical growth". The stereo mapping feature collection method has been applied to capture urban centres' morphology change. Detailed buildings in 3D from stereo mapping were analyzed from the perspective of change in building height, lot coverage and floor area ratio. This paper will provide insights into the stereo mapping feature collection, geospatial analysis and modelling to support regional policymaking. Stereo mapping in urban planning allows us to transition from traditional 2D regional planning into 3D regional planning and gives us a new perspective on how our cities develop.
