Canadian LiDAR Data

Since starting our Open Data Resources list in 2010, we have received thousands of requests to help people find various Canadian data to use with their geospatial projects. And in that time have started an unofficial list of places where LiDAR data that is available for the public to use.

Today we are making our list available to our readers in the hopes that more people can make use if this data and that the geospatial community might help add more sources to it.

Bathymetry is used to measure water depths to help model physical underwater terrain found beneath large bodies of water. Similar to the same way that LiDAR models are represent 3D features (or relief) of land terrain, bathymetric maps illustrate the terrain or land that is located under large bodies of water.

How to Get Ontario Topographic Data

Recently, someone contacted me looking for information on where they could find topographic map data for the Thunder Bay area, so I assumed that they must have already checked the Canadian data page, so suggested that they check out the Ontario Basic Mapping web site (OBM).

The Ontario Basic Mapping (OBM) site by the Geography Network is a great online resource with simplistic interactive interface that provides users tools to create customized map views and the ability to download various topographic base mapping data for the entire Province of Ontario. The site contains GIS layers created from 1:10,000 base maps from the Ontario Ministry of Natural Resources that people can download including layers for transportation, water, municipal, elevation, parks and conservation areas.

Today I have included more information about the OBM including a video on how to download free topographic data from the site.
