Create a feature stateset

Feature statesets define dynamic properties and values on specific features that support them. This article explains how to create a stateset that defines values and corresponding styles for a property and changing a property's state.

Prerequisites

• Successful completion of Query datasets with WFS API.
• The datasetId obtained in the Check the dataset creation status section of the Use Creator to create indoor maps tutorial.

Important

• This article uses the us.atlas.microsoft.com geographical URL. If your Creator service wasn't created in the United States, you must use a different geographical URL. For more information, see Access to Creator Services.
• In the URL examples in this article you will need to replace:
  • {Azure-Maps-Subscription-key} with your Azure Maps subscription key.
  • {datasetId} with the datasetId obtained in the Check the dataset creation status section of the Use Creator to create indoor maps tutorial

Create the feature stateset

To create a stateset:

Create a new HTTP POST Request that uses the Stateset API. The request should look like the following URL:

https://us.atlas.microsoft.com/featurestatesets?api-version=2.0&datasetId={datasetId}&subscription-key={Your-Azure-Maps-Subscription-key}

Next, set the Content-Type to application/json in the Header of the request.

If using a tool like Postman, it should look like this:

Finally, in the Body of the HTTP request, include the style information in raw JSON format, which applies different colors to the occupied property depending on its value:

{
    "styles":[
        {
            "keyname":"occupied",
            "type":"boolean",
            "rules":[
            {
                "true":"#FF0000",
                "false":"#00FF00"
            }
            ]
        }
    ]
}

After the response returns successfully, copy the statesetId from the response body. In the next section, you'll use the statesetId to change the occupancy property state of the unit with feature id "UNIT26". If using Postman, it appears as follows:

Update a feature state

This section demonstrates how to update the occupied state of the unit with feature id "UNIT26". To update the occupied state, create a new HTTP PUT Request calling the Feature Statesets API. The request should look like the following URL (replace {statesetId} with the statesetId obtained in Create a feature stateset):

https://us.atlas.microsoft.com/featurestatesets/{statesetId}/featureStates/UNIT26?api-version=2.0&subscription-key={Your-Azure-Maps-Subscription-key}

Next, set the Content-Type to application/json in the Header of the request.

If using a tool like Postman, it should look like this:

Finally, in the Body of the HTTP request, include the style information in raw JSON format, which applies different colors to the occupied property depending on its value:

{
    "states": [
        {
            "keyName": "occupied",
            "value": true,
            "eventTimestamp": "2020-11-14T17:10:20"
        }
    ]
}

Note

The update will be saved only if the time posted stamp is after the time stamp of the previous request.

Once the HTTP request is sent and the update completes, you receive a 200 OK HTTP status code. If you implemented dynamic styling for an indoor map, the update displays at the specified time stamp in your rendered map.
