4. What is Python?
• Python was created in 1990 by Guido van Rossum
“Python is an easy to learn, powerful language… (with) high-level
data structures and a simple but effective approach to
object-oriented programming. Python’s elegant syntax and
dynamic typing…make it an ideal language for scripting…in many
areas and on most platforms.” –python.org
• Scripting language of ArcGIS
• Free, cross-platform, easy to learn, widely used, great
community

5. Why Python?
• Automating workflow
• Productivity (faster)
• Cross platform
• Industry and Open Standards
• Scripting language
• Extend Model builder
• Scheduled tasks
• Standard install with ArcGIS
• Integrated with ArcGIS (ArcPy)

6. ArcGIS integration (ArcPY)
• Creates a useful and productive way to execute geographic
data analysis, data conversion, data management, and map
automation within the Python framework.
• ArcGIS applications written with ArcPy provide access to
numerous additional libraries available in the Python
community.
• GIS professionals and programmers can
benefit from integration with these
various disciplines.

7. Where does it fit in?

8. Automate Workflow (Desktop)
• Extending Geoprocessing in model builder
• Automating repetitive tasks
• Scheduled tasks
• Bulk metadata reporting
• Multiple Layouts

9. Automate Workflow (Desktop)
• Attribute manipulation
• Geometry manipulation &
automation
• Integrate 3rd party functions
(non-Esri)

10. Demo (Desktop)
• Field calculator
• From model to script
• Script scheduling
• Batch process with log
• Batch process with email
• Batch metadata extraction
• Enhanced Data Driven Pages
• Geometry operations
• Sample Scripts

11. Demo (Desktop)
• ArcPY Documentation / Help reference
• Python window – (run buffer example)
• ArcPY list function – (list layers or MXD’s)
• Working with selections – (sample from training)
• Geometry – (sample from training)
• Sharing Geoprocessing package – (buffer / clip tool)

12. Automate Workflow (Server)
• Geodatabase admin tasks (compress)
• ArcGIS Server admin tasks (start /stop services, status, logs)
• Geoprocessing – Data extraction (clip & ship)
• Printing (script)
