USGS Landsat
USGS Landsat is a joint NASA-USGS Earth observation satellite program that provides continuous, moderate-resolution imagery of the Earth's surface since 1972. It offers multispectral data for monitoring land use, vegetation health, water resources, and environmental changes over time. The platform includes satellite missions, data archives, and tools for accessing and analyzing geospatial imagery.
Developers should learn USGS Landsat for building applications in environmental monitoring, agriculture, urban planning, and climate research, as it provides free, long-term satellite data essential for geospatial analysis. It's particularly useful when creating tools for remote sensing, GIS integration, or data visualization that requires historical or real-time Earth observation data.
