Topographic maps, scanned thematic maps, remote sensing images TM/ETM, ASTER, OSM databases, and other data sources
Using remote sensing software such as GIS and ENVI to accurately correct the required images, ensuring that the error of adjacent images is less than one pixel. Then, after digitization, spatial and attribute data are extracted, organized, and edited strictly according to the 100000 scale requirements
Corrected planning maps, maps, and remote sensing images and other data
