Canada's First Aeronautical Charts And The Eight mile Map Series
In 1926, the Department of the Interior commenced publication of experimental air charts and air navigation strip maps. Encouraged by the favourable reception of these early efforts, it was decided in 1932 to embark on the publication of a chart series for air navigation in Canada. Because the RCAF was interested in this project, the Department of National Defence volunteered to help with the chart design. The result of this initiative was the Ca…

The Land Surveys Of Ontario 1750–1980
The author discusses land survey systems in the lands bordering the northern shores of the Great Lakes from the late 18th century through to the present day. In the early period during the French regime settlement was discouraged in favour of the fur trade and, consequently, very little surveying was done. After the fall of Quebec, the British continúed this land survey policy until the arrival of the Loyalists during and after the American Revol…
The Importance Of Map Libraries In Atlas Production
The One Inch to One Mile Series of the National Mapping Program
The Canadian one inch to one mile series was begun in 1904 and ended in 1949 when it was converted to the 1:50,000 scale. During the early days much assistance was given by personnel loaned from the British Ordnance Survey and consequently the style of the early sheets exhibits this influence. Shortly after the first world war a gradual change was made away from the plane-table and towards the new techniques of photogrammetry. This change was com…

This paper traces the history of Canadian topographic maps at scales between 1:20,000 and 1:31,680 from 1916, when the first sheet in this range was published, to the time when these scales were standardized at 1 :25,000. Lists are included of sheets that were available at various dates, and a short description is given of the different projections used. Cet exposé retrace l'histoire des cartes topographiques à l'échelle variant de 1/20,000 à 1/3…

The 1
In 1972 the Surveys and Mapping Branch in Ottawa decided to expedite the production of northern topographical maps by publishing a monochrome version of the standard 1:50,000 map. This paper examines the specifications of this new series. One aspect of the production of the monochrome series was the necessity to re-design certain symbols. No diminution of accuracy or content has been allowed, but some loss of readability has resulted from the lac…

The User’s Influence in Specific Design Problems
The 1:50,000 map series is very important in Canada because it is the largest scaled, most detailed mapping that exists for most of the country. Because of the size of Canada, the varying nature of its physical geography, and the uneven distribution of its population, special problems are being encountered in the production of the eventual 13, 150 sheets of this series. These problems and some of their solutions are covered in this paper. La séri…
The History of the 1
This paper traces the progress and development of the 1:250,000 map series of Canada from its inception in 1923 through to publication of the final map sheet in 1970. Originally, the maps were published at 1:253,440 up until 1949 when, by international agreement, Canada converted its basic map series from duodecimal scales to the present 1:50,000, 1:250,000 and 1:500,000 scales. Commencement of the series in 1923 marked the beginning of a nationa…
Photo Maps for Resource Development in Canada
The present-day exploitation of natural resources demands up-to-date large-scale maps at a rate that exceeds the capability of traditional methods of map production. The writer suggests that the modern photomap may provide the answer to the map-makers' dilemma, and he describes the five different types of photomaps now being produced by Surveys and Mapping Branch, Ottawa, ranging in accuracy and cost from the orthophoto map to the uncontrolled mo…
The Three-Mile Sectional Maps of the Canadian West
Soon after the Confederation of Canada in 1867, settlement of the Prairies was initially assisted by the preparation of large-scale survey plans. Popular demand for maps at a more convenient scale prompted the Federal Department of the Interior to establish a map series at 6 miles to 1 inch in 1873. By 1891, it became evident that the scale was too small to show necessary map detail and accordingly the Department authorized a new series at 3 mile…
