Historical Topographic Maps Digitization Project

The Ontario Council of University Libraries (OCUL) Historical Topographic Map Digitization Project is a province-wide collaboration to inventory, digitize, georeference, and provide broad access to early topographic maps of Ontario. The collection provides open access to georeferenced topographic maps at the 1:25,000 and 1:63,360 (one inch to one mile) scales, covering towns, cities, and rural areas in Ontario over the period of 1906 to 1977. The project adds over 1000 maps to our collective digital holdings.

Ontario universities have contributed their support by supplying and scanning maps, georeferencing the digital images, creating metadata for the records, and developing the online geographical display of the maps for the public to access.

Topographic maps at these scales are heavily used by researchers interested in examining changes over time, such as urban sprawl, transportation patterns, diminishing woodlots, or shoreline erosion.

The OCUL Geo Community is a forum for the exchange of information and ideas pertaining to maps, geospatial data, and other cartographic resources, both print and digital, within the wider Ontario Council of University Libraries community.
