Browse OGC API feature service

Browse an OGC API feature service for layers and add them to the map.

Use case

OGC API standards are used for sharing geospatial data on the web. As an open standard, the OGC API aims to improve access to geospatial or location information and could be a good choice for sharing data internationally or between organizations. That data could be of any type, including, for example transportation layers shared between government organizations and private businesses.

How to use the sample

Select a layer to display from the list of layers shown in an OGC API service.

How it works

1. Create an OgcFeatureService object with a URL to an OGC API feature service.
2. Obtain the OgcFeatureServiceInfo from OgcFeatureService.ServiceInfo.
3. Create a list of feature collections from the OgcFeatureServiceInfo.FeatureCollectionInfos
4. When a feature collection is selected, create an OgcFeatureCollectionTable from the OgcFeatureCollectionInfo.
5. Populate the OgcFeatureCollectionTable using PopulateFromServiceAsync with QueryParameters that contain a MaxFeatures property.
6. Create a feature layer from the feature table.
7. Add the feature layer to the map.
