This topic contains information about accessing and using the GeoAnalytics Tools in the Portal for ArcGIS map viewer. This information applies to all GeoAnalytics Tools.
Access the tools
To access and use GeoAnalytics Tools in the map viewer, follow these steps:
- Open a web map in the portal 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.
- 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 Python API
ArcGIS Python API 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.
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.
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.
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.
Layers and data you can analyze
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.
- 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.
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
- Hosted WFS layers
The layer must have the query capability enabled.
- Comma-separated values (CSV) file (.csv)
- Shapefile (.zip)
- Map notes
- WFS layers
Analysis tools you run in the 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.
