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.
