Using Python for Efficiency and Innovation with ArcGIS Amy Smith Fehr &

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

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.

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”.

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?

Use Case: Standalone Scripts Example #1: Automated Map Production

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

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

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

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

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

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.

Thanks! Amy
