Historical Topographic Map Digitization Project
Preserving Ontario’s Past
The Historical Topographic Map Digitization project was initiated by the Ontario Council of University Libraries (OCUL) Geo Community in 2014. It is a 2.5 year initiative to digitize and georeference early-to-mid 20th century historical topographic maps covering the province of Ontario at the scales of 1:25,000 and 1:63,360. The goal is to create and provide access to high-resolution map scans that preserve historical topographic information and meet the needs of current and future users.
The maps on the home page represent a sampling of the over 1000 maps in the historical topographic maps collection. Please select Full Collection below to view more.
Ottawa, Ontario. 1:25,000. Map Sheet 031G05G, ed. 3, 1971
This is a georeferenced raster image of a printed paper map of the Ottawa, Ontario region (Sheet No. 031G05G), published in 1971. It is the third edition in a series of three maps, published between 1961 and 1971, and is unusual in that coverage extends into the United States of America. In many of these cases, information was obtained from the U.S. American Mapping series, before being scribed by the Canadian Design Service.
The photograph used to create this map was originally taken in 1968, by the Survair Limited, based out of Ottawa, ON, Canada. These various surveys were under the Surveys and Mapping Branch of the Department of Energy, Mines and Resources, Government of Canada.
