Canada was a difficult territory to map. Planning, effort and overall cost were comparable to building the Canadian Pacific Railway or the St-Lawrence Seaway. "Mapping a Northern Land" recounts the immense human effort it took to define this vast country. From the naming of Canada's places and features to the role Canada has played internationally in mapping and surveying, this volume continues the story of surveying, photogrammetry, and cartography launched by the three-volume "Men and Meridians". Twenty-three specialists describe the birth and development of remote sensing, especially valuable because many areas are difficult to access, and geographical information systems, a Canadian innovation. They also provide information on developments in geodesy, topographic mapping, remote sensing, navigational charting, and geographic information systems during a period of tremendous technological change. For those interested in the maps, "Mapping a Northern Land" explores federal and provincial map and chart styles, a wealth of atlases, and the numerous thematic maps produced in Canada.
