Topography (lidar point cloud) data of the Trail Islands in BC, Canada

This is a lidar point cloud (ground reflections only) sliced to the small Trail Islands to the North of Vancouver. The islands have some nice looking topography and their isolated nature creates problems for some interpolation methods.

The horizontal datum is WGS84 and the elevation is referenced to “mean sea level”.

There are ~800,000 measurements in total with 3 columns available: longitude, latitude (geodetic), and ground elevation (orthometric).

Format: CSV with xz (lzma) compression.

Load with: pandas.read_csv
