.NET spatial restriction SOI

This sample illustrates how to develop an SOI to apply certain spatial restrictions on the Export Map, Identify, and Find REST operations of a map service. It contains two sample SOIs, Clipping SOI and SpatialFilter SOI. Clipping SOI masks out layers outside of a clip polygon to draw or query, whereas SpatialFilter SOI draws or queries only features that meet the spatial filter criteria defined from the SOI. The spatial restriction logic provides a fine-grained resource access control with the support of spatial factors.

Note : This sample SOI is only applicable to map services published from ArcGIS Pro to a 10.8 or later versions of ArcGIS Server. See what's new in the ArcGIS REST API at 10.8.

Deploying the SOI from the .soe file (..\bin\Release\NetSpatialRestrictionSOI_ent.soe) does not require you to open Visual Studio. However, you can load the project (..\NetSpatialRestrictionSOI.csproj) in Visual Studio to debug, modify, and recompile the SOI code.

Features

• Preprocess REST requests
• Spatial Filter

Sample data

This instruction uses the USA map service as the sample service to test with the SOI.

Instructions

Deploy the SOIs

1. Log in to ArcGIS Server Manager and click the Site tab.

2. Click Extensions.

3. Click Add Extension.

4. Click Choose File and choose the NetSpatialRestrictionSOI_ent.soe file (..\bin\Release\NetSpatialRestrictionSOI_ent.soe or ..\bin\Debug\NetSpatialRestrictionSOI_ent.soe).

5. Click Add.

   

Enable the Clipping SOI on a map service

1. Make sure you have published the USA map service using ArcGIS Pro. If not, refer to USA map service
2. Log in to ArcGIS Server Manager and click the Services tab. Select USA map service and select Capabilities.
3. In the Interceptors section, select Clipping SOI in the Available Interceptors box and click the right arrow button to move it to Enabled Interceptors.
4. Click the Save and Restart button to restart the service.

Test the Clipping SOI

1. Open a browser and navigate to the REST services endpoint of the USA map service (URL: http://<serverdomain>/<webadaptorname>/rest/services/USA/MapServer).

2. Scroll to the bottom of the above page and click Export Map in Supported Extensions.

   This leads you to the following URL:

   http://<serverdomain>/<webadaptorname>/rest/services/USA/MapServer/export?bbox=-178.85719640187426,13.522152002873426,-56.484036397641795,81.72479317856566
   

   The exported image shows the map in a circle area. Alternatively, try to view this map service in ArcGIS JavaScript or ArcGIS Online Map Viewer and you should see similar result:

   

3. You can play around the Export Map, Identify and Find operations to observe the SOI's effects.

Enable the SpatialFilter SOI on a map service

1. Navigate back to the USA map service in ArcGIS Server Manager.
2. In the Interceptors section, select Clipping SOI in the Enabled Interceptors box and click the left arrow button to disable this SOI.
3. Select SpatialFilter SOI in the Available Interceptors box and click the right arrow button to move it to Enabled Interceptors.
4. Click the Save and Restart button to restart the service.

Test the SpatialFilter SOI

1. Open a browser and navigate to the REST services endpoint of the USA map service (URL: http://<serverdomain>/<webadaptorname>/rest/services/USA/MapServer).

2. Scroll to the bottom of the above page and click Export Map in Supported Extensions.

   This leads you to the following URL:

   http://<serverdomain>/<webadaptorname>/rest/services/USA/MapServer/export?bbox=-178.85719640187426,13.522152002873426,-56.484036397641795,81.72479317856566
   

   The exported image shows the map in a limited area. Alternatively, try to view this map service in ArcGIS JavaScript or ArcGIS Online Map Viewer and you should see similar result:

   

3. You can play around the Export Map, Identify and Find operations to observe the SOI's effects.
