arcgis.geoanalytics.analyze_patterns module¶
These tools help you identify, quantify, and visualize spatial patterns in your data.
calculate_density takes known quantities of some phenomenon and spreads these quantities across the map. find_hot_spots identifies statistically significant clustering in the spatial pattern of your data.
