"The Glacier Atlas of Canada is a collection of maps produced as part of the Canadian Glacier Inventory Project. This project was initiated as part of Canada's contribution to the International Hydrological Decade (1965 to 1974). Although publication of this map series was suspended in the...

The International Map of the World (IMW) series provided uniform coverage of the World at the scale of 1:1,000,000 according to United Nations specifications.

The map shows the six major drainage areas in Canada, the major diversions in 1975 and the flow (in cubic metres per second) of rivers whose mean annual flow at the outlet of their river basin exceeds 400 cubic metres per second. The Mackenzie and the St. Lawrence rivers have the two largest...

The map shows the location and distribution of bedrock aquifers. The quality is expressed by the total dissolved solids in parts per million and the quantity is expressed in litre per second. Bedrock deposits consist of sedimentary, metamorphic, and igneous rocks; Canada possesses all three...

The International Map of the World (IMW) series provided uniform coverage of the World at the scale of 1:1,000,000 according to United Nations specifications.

The map shows isolines on four different dates: 1) the day of the year when there are less than or equal to 2.5 centimetres of snow that occurs and remain absent for 7 or more days; 2) the standard deviation of the mean date of snow cover loss; 3) the day of year when greater than or equal to 2.5...

The map shows the mean daily temperatures based on the 30-year period 1941-1970 for the warmest month in Canada. Although, the most direct and the most intense incoming solar radiation occurs in June, there is a lag in the warming of the Earth’s surface. As a result the warmest month in Canada is...

The map shows the annual snowfall (in centimetres) based on the 30-year period 1941-1970. Snowfall is measured by inserting a ruler into the new snow at several points to obtain its depth and to estimate the degree of drifting or scouring that has occurred. The water equivalent of snowfall for...
