Automating GIS Workflows with Python Scripts
This week I am presenting a session titled Automating Workflows with Python at the Pennsylvania GIS Conference. The session walks people through the process of creating a Python script that can be set-up as a Windows Scheduled Task. This would allow simple tasks like data replication and rebuilding address locators to automatically run on a weekly … Continue reading Automating GIS Workflows with Python Scripts
Script Example: Move and Unzip File; Rename Zipped File
