Maps & Aerial Photography

The Maps, Data and Government Information Centre (MaDGIC) serves as the campus centre for geospatial and numeric data, statistics, government publications, aerial photography, maps and other cartographic resources.

The map collection includes ca. 82, 236 sheet maps and an extensive collection of aerial photographs, atlases, gazetteers, manuals and guides. The collection is mainly comprised of Canadian sources, but other countries are well represented. We are a member of Communication Canada's Map and Chart Depository Program, which means we receive paper copies of topographic maps of Canada at all published scales, as well as maps published by the Geological Survey of Canada, and a variety of thematic maps.

Most Map Collection materials can be accessed through Trent University Library’s web catalogue, OMNI. Indexes to topographic maps are found within our collection.
