Toronto 3d Open Data

kita tunggu kota di Indonesia …

Owen Powell


The City of Toronto has created a fantastic 3d city model and recently released it as open data. This is probably a bit more of a simpler use of the data than they had in mind, but you could do a lot, especially when combining it with some of their other datasets. Ideas, anyone?

I used FME to process the GIS data and Blender to render it. This render consists of a mix of detailed ESRI multipatch features and low-poly extruded building footprints to keep the file sizes down. In FME I filtered the multipatch models on height (taken from the BoundsExtractor) to extract features more than 200m. I then filtered the shapefile building footprints to find all less than 200m, and extruded them (from an attribute in the data) and wrote out to an OBJ file.
