Canadian LIDAR Images Web Mapping Service

These airborne terrestrial and coastal LIDAR (Light Detection and Ranging) data were collected along sections of the Canadian Atlantic and Arctic coasts by the Geological Survey of Canada with various partners and collaborators. The data sets consist of gridded elevation measurements converted to geo-referenced images and then made accessible via an OGC-compliant Web Mapping Service.

These data sets are used to develop coastal terrestrial Digital Elevation Model (DEM) for flood extent mapping, for geomorphic interpretation, for orthorectification of data sets, and as underlying DEMs for other data sets."
