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.
Sault Ste. Marie, Ontario. 1:63,360. Map Sheet 041K09, [ed. 1], ungridded, 1939
This is a georeferenced raster image of a printed paper map of the Sault Ste. Marie, Ontario region (Sheet No. 041K09), published in 1939. It is the first and only edition of this map, and is unusual in that the map was extended in order to include an area outside of the index grid, the Peninsula. A gridded version of this map (MB Grid System) was also published in the same year.
The survey for this map was conducted in 1937 using imagery taken by the Royal Canadian Air Force, as part of a national topographical survey originally commissioned by Department of Militia and Defence in 1904. This survey was completed by the Geographical Section, General Staff, Department of National Defence.
