LiDAR which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure variable distances to the Earth’s surface. The result is a very detailed point cloud dataset allowing users to visualize the bare earth (last pulse return) or canopy (first pulse return) and anything in between.
The data sources below are sample datasets provided as is for teaching and research purposes. Students are encouraged to examine and process the imagery using Geographic Information Systems.
Original data is compressed in RAR format and unzipped using 7-Zip software. The resulting .las files provide LiDAR coverage over Niagara Falls to the Whirlpool gorge.

Niagara Falls (Terrasolid)
These data include a subset of the above Niagara Falls LiDAR collection with additional files prepared for use with Terrasolid software. Although the MDGL doesn’t support this software, these data may be of use to the curious remote sensing explorer.
