  1. Using Python for Efficiency and Innovation with ArcGIS Amy Smith Fehr & Peers @wolfmapper

  2. Why Use Python with GIS? Because Python is Spatial! • Python + GIS • Organizing workflows for reusability • Automating common tasks • Creating custom tools • Sharing desktop geoprocessing via web applications

  3. Use Case: Using Python in Field Calculations • Example #1: Assigning Random Values to A Field I need to create a sample distribution of average parking duration that will be filled in with data when it becomes available.

  4. Use Case: Using Python in Field Calculations • Example #2: Finding and Replacing Text I want my street labels to read as “Avenue” instead of “Ave”.

  5. Use Case: Using Python in Field Calculations • Example #3: Preparing Tables for Joining The GEOID in my Census geography is numeric, and I need to join it to a table that uses a text data type for the GEOID. The numeric version is missing the “0” that should proceed single-digit state FIPS codes. Can you convert the field to text and add the extra “0” where needed?

  6. Use Case: Standalone Scripts • Example #1: Automated Map Production

  7. Use Case: Standalone Scripts • Example #2: Analyzing and Visualizing NextBus XML Feeds

  8. Use Case: Custom Script Tools • Example: The Placer County Segment Analysis Tool

  9. Use Case: Geoprocessing Services • Example: The Laguna Ridge Dynamic Trips Tool

  10. Use Case: Geoprocessing Services • Example: The Laguna Ridge Dynamic Trips Tool From ArcGIS Desktop Script Tool to Web Geoprocessing Service

  11. Use Case: Geoprocessing Services • Example: The Laguna Ridge Dynamic Trips Tool

  12. Learning More • Books • A Python Primer for ArcGIS Nathan Jennings • Python for Geospatial Development Erik Westra • Learning Geospatial Analysis with Python Joel Lawhead • Programming ArcGIS 10.1 with Python Cookbook Eric Pimpler • Websites • Python.org • ArcPy Café arcpy.wordpress.com • Codecademy codecademy.com • Stack Overflow stackoverflow.com • GIS Stack Exchange gis.stackexchange.com • ArcGIS Forums forums.arcgis.com • Friends (I know you’re out there!)

  13. In Closing • Using Python with ArcGIS Desktop and Server opens up new workflow efficiency and innovation possibilities. • Python also has many other strengths and can be used with open-source toolkits as well (spatial and non-spatial). • There’s a fantastic user community that’s incredibly supportive and geared toward progress.
