Map Algebra in Python
summary
Shows how to work with ArcPy in Python: installing ArcPy, calling geoprocessing tools, and running a 500-meter buffer on a river. Demonstrates classifying multi-temporal rasters from 2013, 2016, 2019, and 2021 to measure change, computing kernel density from dolphin tag data with ~150 m satellite precision, using local/focal/zonal/global functions, reclassifying into 20 categories, automating workflows, and producing reproducible maps and layers via Python scripts.
