Satellite image analysis is the extraction of information from Earth observation imagery: detecting objects, classifying land cover and measuring change between dates. AI satellite image analysis does this with trained models instead of manual interpretation, so the same question can be answered over thousands of sites every time a new image arrives.
Change detection is where it pays and where it fails. A field looks different after harvest, a roof after rain, a coastline at another tide; clouds, shadows and sensor angle change everything. A system that flags every difference is ignored within a week. So the model is trained to find the changes you care about, compares like with like (season, sensor, time of day), and uses radar when optical imagery is clouded out.
