Introduction to Geoprocessing Scripts Using Python

Strictly by pre-registration only

What is this course about?

This course uses Python's language syntax and modules to access and automate geoprocessing workflows through Python scripts. These scripts can be run inside of the Python Integrated Development Environment, within the Python window in ArcMap, as custom tools within ArcToolbox, or shared as geoprocessing packages.

This course covers the ArcPy site package, which integrates Python scripts into the ArcGIS platform. With ArcPy, your scripts can access additional ArcGIS functionality to work with your maps and data beyond the geoprocessing framework
