  22. Geoprocessing Models • Author using Model Builder • Chain tools to perform a workflow • Use models like ArcToolboxtools • Use models within other models • Apply all Model Builder techniques to network analysis models ArcGIS Network Analyst: Automating Workflows with Geoprocessing

  23. Example: Service Area Model ArcGIS Network Analyst: Automating Workflows with Geoprocessing

  24. Demo Automating workflows with geoprocessing models Performing a network analysis in Model Builder Sharing a model as a tool ArcGIS Network Analyst: Automating Workflows with Geoprocessing

  25. Takeaways Demo: Automating Workflows with Geoprocessing Models • Automate workflows with Model Builder • Share your model as a tool • Make inputs and outputs model parameters • Inputs can be selected by the tool’s user • Outputs will be added to the ArcMap Table of Contents ArcGIS Network Analyst: Automating Workflows with Geoprocessing

  26. Visualizing analysis results in ArcMap • When running models as tools… • The output network analysis layer should be a model parameter • This will add the layer to the ArcMap Table of Contents ArcGIS Network Analyst: Automating Workflows with Geoprocessing
