Recherche dans la collection - Annotated Sectional maps of Western Canada, six miles to one inch, old style [cartographic material]

In 1919 the Dept. of the Interior decided to change the sectional maps series from a cadastral to a topographic series. The manuscript features on each map were used to convert from the old series to the new series by the addition of contours, buildings, roads, etc.

The coloured lines indicate the lines of spirit levels that were surveyed ca. 1925. The numbers along the lines probably refer to the field notebooks of the surveyors. These old style maps with manuscript additions would then be reprinted as new style maps with subdued grid lines and with the edition statements removed.

The base maps, which show townships, ranges, trails, post offices, railway stations, and other details, were originally published by the Surveyor General (Dept. of the Interior), for departmental use, at the listed scale of one inch to six miles. The same maps, published at one inch to three miles would have been made available to the public.

Transferred to the Public Archives of Canada by Topographical Surveys, Surveys and Mapping Branch, Energy, Mines & Resources Canada in 1980.

Scale 1:380 160.

Published versions of the new style maps can be found in: G3465 s380 .C35.
