Lidar, Cloud Point and Raster Elevation Data

Description

The Geospatial has a wide variety of elevation and related data available from a variety of sources. Recently acquired is the Ontario Classified Point Cloud (Lidar-Derived) data from OMNRF. This data consists of points containing elevation and intensity information derived from returns collected by an airborne topographic lidar sensor. The minimum point cloud classes are Unclassified, Ground, Water, High and Low Noise. The data is structured into non-overlapping 1-km by 1-km tiles in LAZ format and is available for most areas of Ontario. See map for coverage and years available. 

Additionally, the Geospatial Centre has provincial Lidar and DEM/DTM/DSM data through provincial projects like COOP (2016), DRAPE (2014), NWOOP (2017), SCOOP (2013), and SWOOP (2015).
