The Digital 1:1,200 Topographic Maps is a collection of scanned and vectorized hardcopy maps (paper format) of the Ottawa/Gatineau region. The range of years of the maps are from 1934 to 1979. The hardcopy maps were sent out to be scanned in the summer of 2007. The hardcopy maps are currently archived at the Carleton University Library storage facility.
Some of the maps are available for direct download through this interactive index, while others can only be obtained by visiting the Maps, Data & Government Information Centre (MADGIC) desk.
The maps were scanned at 300 dpi by Kovatec Inc., an Ottawa based company. They were saved as uncompressed TIF files along with the following processing operations:minor crop, deskew, global despeckling and rotation to proper aspect. In addition,Kovatec Inc. carried out an automatic raster to vector conversion, from TIF files to AutoCAD 14 (.dwg) files.
The digital maps do not have a spatial reference, but can be georeferenced using a GIS.
