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, 24, 063 aerial photographs, and an extensive collection of atlases, gazetteers, manuals and guides. The Map Collection covers mainly Canadian material but other countries are well represented. We are a Full Depository for maps issued by Communication Canada's Map and Chart Depository Program. Under this Program we receive paper copy of topographic maps of all of Canada at all published scales, maps published by the Geological Survey of Canada, as well as a variety of theme 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.

Historic Air Photos

MaDGIC has over 19, 000 paper air photos produced by the National Air Photo Library between 1929 and 1995. We also have over 2,200 paper photos produced by the Ontario Ministry of Natural Resources between 1969 and 1993.   MaDGIC is currently scanning and georeferencing all historic air photos within our collection. We have created two access points: an index to our historical air photo collection provides summary information on our holdings including on both hard copy and digitized formats.  Photos which have been scanned and georeferenced are available for search, discovery and downloading through our Regional Environmental History Atlas Air Photo web site.  Registered members of Trent University have access to all digitized photos for education purposes. Members of the public have access to all digitized photos which are no longer subject to copyright (photos which are 50 years or older).

Recent Imagery of Ontario

The Ontario Ministry of Natural Resources and Forestry is aquiring and maintaining high resolution imagery for all of Ontario. Southern Ontario is divided into regions, and each region is updated on five year cycles following the Ontario Imagery Strategy. Registered members of Ontario universities may access these imagery through Scholars Geoportal


With the exception of some special collections, maps may be borrowed for 14 days.

Atlases and reference texts do not circulate.
