Staff View: Higher geometric accuracy using GPS derived ground control points for LULC analysis

Higher geometric accuracy using GPS derived ground control points for LULC analysis

Georeferencing in remote sensing imagery provides an integrated validation on the land use land cover (LULC) changes of urban growth. Geometic accuracy in georeferencing can be increased using Global Positioning System (GPS) derived ground control points (GCPs). Providing higher geometric accuracy i...
