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.
The Standard Geographical Classification (SGC) is a system maintained by Statistics Canada for categorizing and enumerating the census geographic units of Canada. Each geographic area receives a unique numeric code ranging from one to seven digits, which extend telescopically to refer to increasingly small areas.
Drylands cover 41.3% of the Earth's land surface, including 15% of Latin America, 66% of Africa, 40% of Asia, and 24% of Europe. There is a significantly greater proportion of drylands in developing countries (72%), and the proportion increases with aridity : almost 100% of all hyper-arid lands are in the developing world.
The Canada Land Inventory (CLI) is a multi-disciplinary land inventory of rural Canada.. Conceptualized in the early 1960s by the Department of Forestry and Rural Development (later the Department of Energy, Mines and Resources), the CLI was a federal-provincial project that lasted from 1963 to 1995 and produced maps which indicated the capability of land to sustain agriculture, forestry ...
Solonetzic soils cover almost 73,000 km 2 (0.7%) of Canada's land area; most occur in southern Alberta, because of the large areas of saline parent material and semiarid climate. The four great groups of Solonetzic soils are based on properties reflecting the degree of leaching.
A city's metropolitan area in colloquial or administrative terms may be different from its CMA as defined by Statistics Canada, resulting in differing populations. Such is the case with the Greater Toronto Area , where its metro population is notably higher than its CMA population due to its inclusion of the neighbouring Oshawa CMA to the east ...
Cumulative CO2 emissions from land-use change (as of 2021). Emissions from land-use change can be positive or negative depending on whether these changes emit (positive, brown on the map) or sequester (negative) carbon (green on the map). Land use is an umbrella term to describe what happens on a parcel of land.
Land use is a description of how people utilize the land and of socio-economic activity. Urban and agricultural land uses are two of the most commonly known land use classes. At any one point or place, there may be multiple and alternate land uses, the specification of which may have a political dimension.
