How do I use the model builder in ArcGIS?

Follow the steps below to see how this works.

1. On the ArcMap menu, select Geoprocessing > Geoprocessing Options.
2. Navigate to the input geodatabase in the Catalog window.
3. Choose the PlanB_Roads feature class and drag it onto the ModelBuilder canvas.
4. Click the Connect button.

What is model parameter in Model Builder?

Any model variable can be set as a model parameter. Variables that are set as model parameters appear as tool parameters when the model is run as a geoprocessing tool, allowing you to specify different data or values for your model to process than what was specified when the model was created.

How are iterate rasters used in ModelBuilder?

To understand the use of Iterate Rasters in ModelBuilder, see the illustration below, where the model resamples grid datasets and extracts a subset for further analysis. The Input Rasters variable is a folder containing grids, images, and TIFFs.

Where are rasters stored in ArcGIS ModelBuilder?

In the image below, the model creates a mosaic using rasters stored in a geodatabase named Arizona, which is stored inside a folder. The iteration has been restricted with the wildcard Ar* and workspace type of file geodatabase so that it only iterates over file geodatabases with names starting with the letters Ar.

How to add iterators to a model in ArcGIS 10?

Right-click the output of Collect Values and check the Add To Display. If the model will be run from the model tool dialog box, then make the output of Collect Values a model parameter, as only the output model parameters are added to display. Iterators replace the series option in Model Properties available prior to ArcGIS 10.

What happens when you add an iterator to a model?

If an Iterator is added to a model, all tools in the model iterate for each value in the iterator. If you do not want to run each tool in the model for each iterated value, create a sub-model/model within a model/nested model that contains only the iterator and add it as a model tool into the main model.
