arcpyanalysis

arcpy.analysis is a module within the ArcPy library that provides programmatic access to tools in the ArcGIS Analysis toolbox. It is designed to automate common spatial analysis tasks in ArcGIS Pro and ArcGIS Desktop by exposing Python-callable wrappers around geoprocessing tools.

The module covers a range of vector-based analysis and data-management operations. Typical tools include overlay and proximity functions such as Buffer, Clip, Intersect, Union, Identity, Spatial Join, Near, and Generate Near Table, as well as dataset management tools like Dissolve. The function names in Python generally follow the pattern of the tool name with a _analysis suffix (for example, Buffer_analysis, Clip_analysis), and they operate on inputs such as feature classes, shapefiles, or rasters, producing new outputs in a defined workspace.

Usage is straightforward for Python developers working with ArcGIS. A script typically imports arcpy, configures the environment with arcpy.env (workspace, scratch workspace, extent, cell size), and calls an analysis function with the required parameters. Example: arcpy.analysis.Buffer_analysis(in_features, out_feature_class, buffer_distance_or_field). Outputs are written to a specified location, commonly a file geodatabase or shapefile.

Compatibility and scope: arcpy.analysis runs within the ArcGIS product installations, requiring a valid ArcGIS license. It is accessible from the ArcGIS Pro Python environment or from ArcGIS Desktop's Python setup. While arcpy.analysis focuses on vector analysis and data-management geoprocessing tasks, raster analysis is primarily handled by the arcpy.sa module. The two modules can be used together in comprehensive automation workflows, and detailed usage is documented in Esri’s ArcGIS Pro or ArcGIS Desktop help resources.
