Not all National Topographic System maps strictly follow the National Tiling System's linear grid. Some maps also, as an "overedge", cover land in an area which would otherwise be covered by an adjacent map sheet, simply because the latter area does not contain enough land in Canada to warrant a separate printing.

The system begins with a large tract of land. This large tract is typically defined by one of the earlier survey systems such as metes and bounds or the Public Land Survey System. A subdivision survey is conducted to divide the original tract into smaller lots and a plat map is created. Usually this subdivision survey employs a metes and bounds ...
The USGS Gap Analysis Program maintains four primary data sets: land cover, protected areas, species and aquatic. The GAP Land Cover Data Set is the most complete map ever produced of vegetative associations for the US. Classified into 551 ecological systems, and 32 modified ecological systems (where human impacts have had an effect).
[4]: 69 The necessity of the disposition of land and other physical assets was the result of the privatization of Canadian National Railway in 1995, as the government had excluded non-rail real estate assets from the privatization and re-activated Canada Lands as a holding company for these assets, and to dispose of high-value assets in urban ...
The Canada Geographic Information System (CGIS) was an early geographic information system (GIS) developed for the Government of Canada beginning in the early 1960s. CGIS was used to store geospatial data for the Canada Land Inventory and assisted in the development of regulatory procedures for land-use management and resource monitoring in Canada.
Aerial photography, land cover data, and digital elevation models all provide coverage data. Generally, a coverage can be multi-dimensional, such as 1-D sensor timeseries, 2-D satellite images, 3-D x/y/t image time series or x/y/z geo tomograms , or 4-D x/y/z/t climate and ocean data.
OTTAWA (Reuters) -Canada plans to ease a housing shortage by leasing public land to developers for construction of affordable houses under a plan unveiled by Prime Minister Justin Trudeau on ...
A supervised classification is a system of classification in which the user builds a series of randomly generated training datasets or spectral signatures representing different land-use and land-cover (LULC) classes and applies these datasets in machine learning models to predict and spatially classify LULC patterns and evaluate classification accuracies.
