ModelBuilder is an interactive canvas for building analysis workflows using the analysis tools available in Map Viewer. Models are created by chaining together data and analysis tools into workflows in which the output of one tool becomes the input for another tool. These workflows can range from routine data management tasks to complex spatial analysis. Models streamline an analysis by enabling iterative workflow runs, automating multistep processes, and documenting workflows.
To access ModelBuilder, you must have an ArcGIS Online subscription account with the following requirements:
- User type—Professional or Professional Plus
- Role—Publisher, Facilitator, Administrator, or a custom role with privileges to create, update, and delete content; publish hosted feature layers; and perform analysis
- Credits—A minimum of 30 credits available for your account.
If the ModelBuilder tab is missing, it may mean you do not have the licensing requirements to use ModelBuilder.
The following feature analysis tools are currently supported: Aggregate Points, Calculate Composite Index, Calculate Density, Create Buffers, Create Viewshed, Create Watersheds, Dissolve Boundaries, Enrich Layer, Filter by Attributes, Find Centroids, Find Hot Spots, Find Outliers, Find Point Clusters, Find Similar Locations, Generate Tessellations, Generate Travel Areas, Interpolate Points, Join Features, Merge Layers, Overlay Layers, Summarize Center and Dispersion, Summarize Nearby, Summarize Within, and Trace Downstream.
The following feature analysis tools are not currently supported to add to a model: Calculate Travel Cost, Choose Best Facilities, Extract Data, Find by Attributes and Locations, Find Closest, and Plan Routes. Summarize Nearby and Enrich Layer do not support using a travel mode when run from a model. Find Hot Spots and Find Outliers do not support using Esri population data.
No, raster functions cannot be added to a model. The Raster Function Editor is a visual programming interface for building imagery and raster function templates similar to ModelBuilder.
Intermediate data in ModelBuilder refers to temporary data created by the tools as the model runs. These outputs do not publish a hosted service, thereby reducing model run time. Intermediate data cannot be saved or visualized on the map and is solely intended to be used as inputs to other tools in the model.
In addition to the model session cost, Enrich Layer and Generate Travel Areas also consume credits at the same rate as the tools run from the tool pane. Credit estimation for these tools is not supported in ModelBuilder. Credit consumption is calculated based on the number of input features for the tool, which cannot be reliably determined in a model before the model is run because some tools in the model may perform spatial operations where the number of output features is unknown until the tool run is complete. If you know the number of inputs for a tool, you can calculate an estimate for the tool run using the credit consumption rates. For information on credit consumption rates for Enrich Layer and Generate Travel Areas, see Understand credits for spatial analysis.
The analysis session disconnects and model runs are cancelled if your internet connection is lost.
If your internet reconnects and you are still logged in to Map Viewer, you can click Save as 
to save a copy of the model. Pending edits are lost if the browser is refreshed, the model is made active, or you are logged out of Map Viewer.
ModelBuilder and ArcGIS Data Pipelines are similar in that they both offer a no code, visual user experience for authoring repeatable workflows on the web. Key differences include the following:
- ModelBuilder automates analysis workflows, using analysis tools in Map Viewer. Data Pipelines automates data integration and preparation workflows, and includes several focused tools that clean, format, and prepare data for visualization and downstream analysis.
- ModelBuilder supports feature layers and tables, with raster data planned for a future update. Data Pipelines supports vector and tabular data. You can also connect to a range of external data sources using Data Pipelines, including Amazon S3, Google BigQuery, Snowflake, feature layers, and uploaded local files, among others.
- ModelBuilder is a capability included in Map Viewer and integrated into Map Viewer analysis. Data Pipelines is an ArcGIS app that is used independently from Map Viewer.
