The Analysis widget allows you to add spatial analysis tools, raster functions, and geoprocessing tools to an app. Spatial analysis tools perform fundamental GIS operations, such as creating viewsheds, creating buffers, converting rasters to features, and routing. Raster functions perform individual operations on raster data, such as converting to grayscale and classifying. Spatial analysis is a type of geoprocessing, but geoprocessing also includes tools that perform data management operations such as sorting, merging, and appending spatial data. You can add 64 built-in spatial analysis tools and more than 100 built-in raster functions, most of which are also available in Map Viewer. You can also add custom geoprocessing tools from your ArcGIS organization and tools published with ArcGIS Notebooks.
Examples
Use this widget to support app design requirements such as the following:
- Many storm drains are connected to lakes, rivers, and oceans, making anything entering a drain a potential pollutant downstream. You want to provide a tool (Create Watersheds) that can help determine where the water entering a storm drain originated.
- A development company plans to construct a new mixed-use development in a city. The development must be located within a quarter mile of shops, restaurants, and a light rail stop. You want to provide a tool (Create Buffers) that can determine if potential sites fit this criteria.
- Foresters need to map tree disease transmission. You want to provide a tool (Find Hot Spots) that can identify regions with statistically significant amounts of diseased or healthy trees.
Usage notes
To use any of the built-in tools, the Analysis widget must be connected to a Map widget. However, you do not need to connect a Map widget if you only add custom tools that do not require layer input.
When you include this widget in an app, the run time widget panel has two tabs. The Tools tab lists any tools you add in the widget's settings. The History tab logs all tools the user runs and shows their statuses (for example, Running, Complete, Cancelled). From the history tab, you can click the options button next to each tool to view details, open the tool, or remove the tool. Click View details to view the results of that analysis. Click Open tool to view a tool's configuration window with the same parameters you previously used.
Web maps keep track of their analysis history, including successful and unsuccessful analyses run outside of Experience Builder (such as in Map Viewer). You can import a web map's analysis history in the widget's settings. Any tools imported from the map's analysis history appear at the top of the History tab and are unremovable at run time.
Note:
You can only import past spatial analyses that involved an Esri built-in tool. The widget currently does not support importing custom tool analyses from a web map's analysis history.
Parameters
After opening a tool, the user fills in the tool's parameters, which are a set of options or settings, such as the input layer to process and where to save the output dataset. Every tool has a unique set of parameters, which can be required or optional. Red circles indicate if a parameter is required. The information button next to each tool parameter offers more information about each parameter.
Note:
The widget currently does not support map service layers as input layers.
The widget currently does not support subtype group layers.Tools have both input and output parameters. Every built-in tool requires the user to specify at least one input layer to be analyzed. There are two ways to specify input data:
- Select layers from the connected Map widget. If the Map widget contains a web map, its layers are available to choose.
- Browse for layers in My Content, ArcGIS Online, or an organization's portal.
Note:
You can only browse for input layers with built-in tools, not custom geoprocessing tools.
The output parameters are the name of the result layer and the name of the folder in My Content where the result is saved.
The optional parameters under Environment settings offer additional control over a tool's results. For example, you can specify an output coordinate system or limit an analysis to a specific geographic extent.
Every geoprocessing tool also has a unique set of parameters. A tool creator can choose to use over 100 parameter data types to supply inputs and return outputs, but not all are supported by Experience Builder. View a full list of ArcGIS Experience Builder-supported geoprocessing data types.
Credits
This widget's built-in spatial analysis tools consume credits. Every tool has an Estimate credits button, which you can use to see how many credits an analysis will consume before you run it, located above the Run and Back buttons. The button indicates whether an analysis does not consume credits.
Licensing requirements
To use the Analysis widget, the user must be signed in with an ArcGIS account that has privileges to perform analysis. If you include the Analysis widget in an app and share the app publicly, the widget prompts users to sign in to an account with privileges.
To use raster analysis tools and raster functions, you must have ArcGIS Image for ArcGIS Online. Your organization administrator can grant you the required privileges to perform analysis.

Custom geoprocessing tools have the following settings:
- Input—All of the tool's input parameters are listed here. You can provide a run time label for each input parameter. Depending on the type of parameter (for example, GPFeatureRecordSetLayer, GPDate), you may be able to select input methods, provide default values, and more. View a full list of supported data types in the table below.
- Output—All of the tool's output parameters are listed here. You can provide a run time label for each output parameter. For some types of parameters (for example, GPFeatureRecordSetLayer and GPString), additional settings appear. You may be able to allow end users to export results, add result layers to the connected map automatically, or define the symbology of the result layer. Check the Ignore this output box to remove that output from the results.
- Option—Provide help documentation for your custom tool. By default, the widget reads the tool's service htm.
- Display tool history from map—Display tools from the map's analysis history in the History tab at run time.
Spatial analysis tools
The Analysis widget's built-in spatial analysis tools include feature analysis tools and raster analysis tools.
- Feature analysis is performed on vector data, which is coordinate-based data that represents geographic features using points, lines, and polygons. You can use feature analysis tools to summarize features based on geographic location, measure distances around or between features, and quantify spatial patterns.
- Raster analysis is performed on raster data, which consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature or elevation. Rasters may be digital aerial photographs, satellite imagery, digital pictures, or scanned maps. You can identify raster analysis tools by the raster tool icon
.

. Users can preview the results of raster functions at run time.
The Analysis widget supports more than 100 raster functions. You can read more about every function in Map Viewer documentation.
Geoprocessing data types
Every geoprocessing tool has a unique set of parameters, which are the set of options or settings that the user configures at run time, such as the input data to process and output dataset. Geoprocessing tools can work with many different types of data as inputs and outputs. However, Experience Builder currently only supports some data types.

Interaction options
The Analysis widget supports data actions, which you can configure on the Action tab of the widget's settings.
Data actions allow the user to perform data processing tasks, such as exporting results, adding results to a map, and viewing results in a table. For example, if you include an Analysis widget and Table widget in an app and turn on the View in table action in the Analysis widget's settings, at run time the user can click View in table to view the results of an analysis in the Table widget.
The Analysis widget is the target of the Set as Analysis input data action, which you can configure on the Action tab of other widgets' settings. You can use this data action to select a feature with another widget and make that feature the input for one of the built-in feature analysis tools or a custom geoprocessing tool. This data action supports features from feature layers, dynamic imagery layers, and tiled imagery layers.
The following widgets support the Set as Analysis input data action:
