Coverage Service

Identifying the areas for which we possess data can prove to be a somewhat laborious task. However, leveraging the coverage service, contingent upon the model or feature accessibility at hand, facilitates the straightforward determination of the precise locations where data capture occurred. This Coverage Service is accessible as a Web Feature Service (WFS).

Using the Coverage Service

The Coverage Service is a Web Feature Service (WFS) which can be accessed through this URL:

https://atlasapi.cyclomedia.com/api/featureserver/wfs

This WFS supports the following operations:

  • GetCapabilities

  • GetFeature

Both HTTP GET request and HTTP POST requests are supported.

Response

The output of a request can be given as Geography Markup Language (GML) version 3.1.1 or as GeoJSON. Default output is GML, but this can be changed using the ‘outputformat’ parameter. The application schemas can be retrieved by the URLs below.

Application schemas

GML application schema

To view the GML application schema, use this URL:

https://atlasapi.cyclomedia.com/api/featureserver/wfs?service=WFS&version=1.1.0&request=DescribeFeatureType&typename=atlas:[feature-type]

GeoJSON application schema

To view the GeoJSON application schema, use this URL:

https://atlasapi.cyclomedia.com/api/featureserver/wfs?service=WFS&version=1.1.0&request=DescribeFeatureType&typename=atlas:[feature-type]&outputformat=application/json

Feature types and properties

Feature Type 'ThirdPartyCoverage'

A feature of the type 'ThirdPartyCoverage' the following properties:

lineString

refers to a type definition used within the Geography Markup Language (GML) for representing geometric properties of linear features, such as lines or curves, in geographic data in a specified spatial reference system (SRS). The longitude and latitude coordinates are in degrees or in meters (depending on the SRS), the height is in meters. Type: gml:pointPropertyType.

customerId

The customer that produces the entry. Type: string.

recordedAt

Timestamp and offset to UTC of the coverage line string. Type: dateTime.

productType

As the third party recordings can refer to many models and features, this property informs the entry's type. Type: string.

processedAt

Timestamp and offset to UTC of the coverage processing. Type: datetTime.

daysSinceCreation

Number of days that the lineString was created. Type: integer.

Exception reporting

When the WFS Coverage service encounters an error while processing a request or when it receives an unrecognized request, this will be returned as an exception report in the response. The format of the XML response is described in OWS Common Implementation Specification:

<ows:ExceptionReport version="1.1.0" 
  xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance 
  xmlns:ows=http://www.opengis.net/ows 
  xsi:schemaLocation="http://www.opengis.net/ows"> 
   <ows:Exception exceptionCode="{the exception code}">
       <ows:ExceptionText> 
           {the error message}
       </ows:ExceptionText>
   </ows:Exception>
</ows:ExceptionReport>

For GeoJSON, the response will be:

{ 
   "exception": { 
      "code": null, 
      "locator": null, 
      "text": "<the error message>" 
   } 
}
