A highly accurate elevation dataset of ground surface topography, derived from aerial Light Detection and Ranging (LiDAR). This 2m resolution version of the bare-Earth LiDAR DEM can be used for a wide range of applications such as 3D spatial analysis (slope calculations, profile creation, volumetric computations), engineering applications (land developments, road design, flood modelling) and 3D terrain visualizations, just to name a few.

DEM of 1m and 20cm resolution are also available on Cityonline.calgary.ca

Aerial Imagery of the 2013 Flood Event in Calgary. From June 19-22, over 250 mm of rainfall and mountain snowmelt caused river levels to rise quickly, causing widespread flooding in southern Alberta. Peak river flow rates were 8x to 12x normal. This was Calgary’s largest flood since 1897.
The Calgary flood 2013 orthophoto was created from aerial photography flown Saturday June 22, 2013 from 8:00 AM to 9:30 AM MDT.
The entire zipped up MrSID download file is 4.25 GB. Alternately, this file has been broken up into smaller townships files. See attachments below.
