Applying Built-Up and Bare-Soil Indices from Landsat 8 to Cities in Dry Climates

, 2018
Arid and semi-arid regions have different spectral characteristics from other climatic regions. Therefore, appropriate remotely sensed indicators of land use and land cover types need to be defined for arid and semi-arid lands, as indices developed for ...
