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).
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.
Global land cover maps for 2015 with a spatial resolution of 100 metres based on data from the Copernicus programme; Annual Regional Land Cover Monitoring System or Hindu Kush Himalaya with a spatial resolution of 30 metres based on Landsat images
The value of the Landsat program was recognized by Congress in October 1992 when it passed the Land Remote Sensing Policy Act (Public Law 102-555) authorizing the procurement of Landsat 7 and assuring the continued availability of Landsat digital data and images, at the lowest possible cost, to traditional and new users of the data.
The geographic information available includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures and land cover. The National Map is accessible via the Web, as products and services, and as downloadable data. Its uses range from recreation to scientific analysis to emergency response.
The CLUE model was modified to CLUE-S (the conversion of land use and its effects at small regional extent) model. Specifically, the CLUE-S model was developed for high-resolution spatial data and regional applications. [7] [8] The model comprises two different modules, spatial (land use allocation) and non-spatial (land use demand). [4]
At present 177 cities high-resolution datasets are available, [4] ... water resources, land cover, and processed satellite data generated by ISRO. [2]
Several ICIMOD researchers are involved in their research in different topics of earth observation science. Among the different remote sensing work, the Regional Land Cover Monitoring System (RLCMS) is most mentionable as that provides a series of 30-m resolution annual land cover maps with harmonized land cover data for the years 2000–2018.
