Use the Auto Layout and Fit to Window buttons to see the big-picture view and zoom in and out as needed.īe sure to save periodically as you build the model by clicking Save on the ModelBuilder tab. Once you click OK to set the tool parameters, the input element displays and the process colorizes.Īs you add processes, the model window may fill up. Tip:If your input data has selected features or records, models like individual ArcGIS geoprocessing tools will process only the selection. Set tool parameters and pay attention to red asterisks. A red asterisk next to an item in a tool dialog box means the parameter is required. In model parlance, gray means not ready to run.ĭouble-click each tool and set its parameters. When you add a tool to a model by dragging it from the Catalog or Geoprocessing pane, its output element is also added, and both elements are light gray. Each output can become input for the next process. A process consists of three elements: input data, a tool, and the tool’s output. A model consists of one or more processes.
But first, you will need to understand some ModelBuilder vocabulary. You can’t beat ModelBuilder for easy drag-and-drop building and tinkering. With the basic setup done, now comes the fun part. If you’re not sure which tool to use or what a tool’s required inputs are, check the online ArcGIS Pro tool reference.Ī blank canvas for building your model opens. For more complicated workflows, you may want to sketch everything on paper or a whiteboard. If the workflow is simple, just think it through in your head. List the data input, identify the required geoprocessing tools, and describe the desired output. If you’ve never worked with ModelBuilder, here is a simple five- (or six-) step approach to get you started.īefore creating a model, know what you want it to do. Models are workhorses: If built with reuse in mind, they can be your go-to shortcuts for getting lots of geoprocessing tasks done with less work. Models are invaluable for conducting sophisticated spatial analyses and can reveal data relationships that spark ideas and collaboration. Shape, color, text, and symbols are used in models to communicate information about processes and status. Like maps, models you create in ModelBuiler can be navigated because they have built-in directionality. You can think of ModelBuilder as a tool to map a geoprocessing workflow.Ī model is a workflow map.
Included with ArcGIS Pro, ModelBuilder has been called a visual programming language. Reference: Mr.ModelBuilder provides a visual canvas to create geoprocessing models that automate GIS workflows.
