Introduction to Geoprocessing Scripts Using Python

Strictly by pre-registration only

What is this course about?

Python scripts can reduce the time spent on complex or repetitive tasks, enabling GIS staff to be more productive. This course will teach you how to create Python scripts to automate tasks related to data management, feature editing, geoprocessing and analysis, and map production using ArcGIS. You will also learn how to share your Python scripts, so your key GIS workflows are accessible to others.

This course is designed for GIS analysts, specialists, data processors, and others who want to automate ArcGIS tasks and workflows.
