The 1:1,250 Historical Topographic Maps is a digital collection of scanned and vectorized hardcopy maps (Mylar format) of the Ottawa/Gatineau region. The range of years of the maps are from 1968 to 1978. The hardcopy maps were sent out to be scanned in the summer of 2007. In addition, the city of Ottawa provided digital files of their maps that had been previously scanned. Only the tiles that added coverage to the series were used from the city of Ottawa. The hardcopy maps are currently archived at the Carleton University Library storage facility.
The online maps are available in TIFF, MrSID, PDF and AutoCAD formats.
