This topic contains information about accessing and using the GeoAnalytics Tools in Map Viewer. This information applies to all GeoAnalytics Tools.
This topic discusses the GeoAnalytics Tools available through your portal enabled with ArcGIS GeoAnalytics Server. For information about the standard feature analysis tools, see Perform analysis. See Understanding analysis in Portal for ArcGIS for an overview of each toolset.
The administrator of your organization needs to enable GeoAnalytics Tools and grant you certain privileges for you to perform analysis on your big data. To use any of the tools, you need the following privileges:
- Create, update, and delete content
- Publish hosted feature layers
- GeoAnalytics Feature Analysis
If you do not have these privileges, you will not see the Perform Analysis option as described below.
To learn more about enabling GeoAnalytics Tools, see Set up ArcGIS GeoAnalytics Server.
Access the tools
To access and use GeoAnalytics Tools in Map Viewer, follow these steps:
- Open a web map in Map Viewer. You can optionally add layers to the map that you want to perform analysis on, or browse for layers when running your tools.
You can not add big data file shares to your web map. You must browse for these layers to run analyses on them.
- Do one of the following:
- Click the Analysis button on the map menu bar.
- Alternatively, hover over the layer you want to analyze and click the Analysis button .
Both actions open the Perform Analysis pane.
Access the tools from ArcGIS API for Python
ArcGIS API for Python allows GIS analysts and data scientists to query, visualize, analyze, and transform their spatial data using the powerful analysis tools available in their Portal for ArcGIS. To learn more about the analysis capabilities of the API, see the documentation site.
The GeoAnalytics Tools can be accessed via the geoanalytics module.
Explore the Feature Analysis pane
The Feature Analysis pane is illustrated below. This pane contains a number of categories and each category contains tools. To view the tools within a category, click the expand or collapse button on the left side of the category.
This example uses standard analysis and GeoAnalytics Tools. If you also have raster analysis enabled, you will need to choose Feature Analysis to see this pane. If you do not have standard analysis enabled, you will only see the GeoAnalytics Tools.
Choose the GeoAnalytics Tools.
Open the Analysis Environments dialog box.
Return to the Details pane.
Expand the category to view tools within.
View help about the category.
View help for the tool.
Work with a tool pane
To open an analysis tool pane, click the tool icon. This opens the tool's pane as illustrated below with the Copy to Data Store tool.
Open the Analysis Environments dialog box for the tool. Learn more about Analysis Environments.
Close the tool pane without running the analysis and return to the Perform Analysis pane.
Get help about a parameter.
Browse Layers to add a big data file share or layer in your portal. Choose Analysis Layer may be visible if your administrator has configured Analysis Layers.
The result of running the analysis is saved to My Content using this name.
You can specify a folder in My Content in which to save the result.
If checked, only the data visible in the current map will be analyzed.
Analysis Environments can be set from the tool pane. Processing Extent, Processing Spatial Reference, and ArcGIS Data Store are used by GeoAnalytics Tools.
Each tool has a different set of parameters. You can always view help for a parameter by clicking the help icon next to the parameter as illustrated above. All tools have a Result layer name parameter where the results of running the analysis are written. You can change this name or use the default value.
Use current map extent
It is recommended that you always check Use current map extent and that you zoom in to the area you want analyzed or set the Processing Extent parameter. Doing so limits the number of features the tool needs to examine when performing analysis. If you uncheck Use current map extent, all features in the analysis layer will potentially be analyzed.
Rerun analysis tools
GeoAnalytics Tools can be rerun by clicking the Rerun Analysis button for a result layer. Rerun Analysis will open the tool that was used to create the layer and repopulate all of the parameters. The tool can be rerun with the same parameters, or the parameters can be updated before the tool is run. Ensure that the output name is unique.
When rerunning, the state of the current map will be honored, including filters, extent, processing spatial reference, data store, input layers, and output folder. If you want to ensure that an analysis is rerun at a specific extent, create a bookmark. If you share your results with the intention of allowing other users to rerun your analysis, you may need to share your input layers as well. If you open a tool using Rerun Analysis and the input layers are not available, a warning will be displayed but the tool can still be run with different inputs.
The Result layer name from the previous iteration will be used when you open an analysis tool using Rerun Analysis. You must create a unique name before rerunning a tool.
Layers and data you can analyze
Some tools only work on certain kinds of feature types; for example, Aggregate Points requires an input layer containing point features.
You have the following options when choosing a layer to analyze:
- Choose a layer from your map.
- Use Browse Layers to choose any layer in the portal to which you have access. Use this option if you want to access feature layers that contain more than one layer, such as the Esri boundary layers, since the Browse Layers dialog box allows you to choose an individual layer within the feature layer. This is the only way to select a big data file share as input to GeoAnalytics Tools.
Tip:Use an asterisk (*) as a wild card when searching for content in the Browse Layers dialog box. For example, if you are looking for a big data file share, search for bigDataFileShare*.
- Use Choose Living Atlas Analysis Layer or Choose Analysis Layer to view and select a layer from a preconfigured analysis group. If the portal administrator has configured the portal to access Living Atlas analysis layers, you will see the first option. If the portal administrator has configured the portal to access layers from a custom group, you will see the second option.
Tip:Use an asterisk (*) as a wild card when searching for content in the Choose Living Atlas Analysis Layer or Choose Analysis Layer dialog box. For example, if you are looking for layers with Australia in their title, search for Aus*.
You can perform analysis on the following types of layers and data:
- Big data file shares
The portal must be able to access the feature service; therefore, the URL to the service must either be publicly accessible or within the same network as the portal and hosting server you use to run the analysis. You cannot perform analysis on layers based on nonaccessible feature services.
- Map service
As with feature services, the map service must be publicly accessible or within the same network as the analyzing portal and hosting server.
- Hosted feature layers
- Shapefile (.zip)
- Map notes
Analysis tools you run in Map Viewer create hosted feature layers as output. These output layers are analyzed in the input spatial reference unless the Processing Spatial Reference is set. The output is saved to the spatiotemporal big data store, where it is stored in GCS WSG84.
If you copy a layer to the relational data store using Copy to Data Store, the output will be stored in the spatial reference it was projected to.
