Feature Type Service

With our Feature Type Service, you can retrieve the polygons that refers to detections based on our imagery, so you can use them in your own mapping application (GIS). The Feature Type Service is available as a Web Feature Service (WFS).


Obtain credentials

Before you can start using the Recording Locations Service, you need to have credentials. If you do not have them yet, please use this form to request access.

Filter capabilities

The Feature Type Service offers filter capabilities that follow the OGC Filter Encoding Implementation Specification.

Geometry operators:

  • gml:Point

  • gml:Envelope

Spatial operators:

  • BBOX

  • DWithin

Comparison operators: (not implemented yet)

  • EqualTo and NotEqualTo

  • LessThan and GreaterThan

  • LessThanEqualTo and GreaterThanEqualTo

  • NullCheck

  • Between

Using the Feature Type Service

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


This WFS supports the following operations:

  • GetCapabilities

  • DescribeFeatureType

  • GetFeature

Both HTTP GET request and HTTP POST requests are supported.


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.

Feature types and properties

Feature 'SurfaceType'

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


Readable identification of the starting image from DCR imagery. Type: string.


Readable identification of the stop image from DCR imagery. Type: string.


Method used to get final geometry. Returns one of these possible values: [ST_Automatic, ST_Manual, ST_Raw]. Type: string.


Informs the detected type of surface. Type: string.


Polygon area. Type: float.


Percentage of polygon predicted with Asphalt. Type: integer.


Percentage of polygon predicted with Clinkers. Type: integer.


Percentage of polygon predicted with Concrete. Type: integer.


Percentage of polygon predicted with Mosaic. Type: integer.


Percentage of polygon predicted with Tile. Type: integer.


Percentage of polygon predicted with Unpaved. Type: integer.


Percentage of polygon predicted with Unknown. Type: integer.


Basic function of polygon (not in use yet, always null). Type: string.


Basic status of polygon. Type: string.


Basic physical representation. Type: string.


Plus function of polygon. Type: string.


Plus status of polygon. Type: string.


Plus physical representation. Type: string.


Date of registration of polygon. Type: dateTime.


Date of termination of polygon. Type: dateTime.


Date of termination of polygon. Type: dateTime.


Represents a type definition designed to encapsulate the properties of polygonal geometries 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:polygonPropertyType.


Date when the feature type was created. Type: dateTime.


Indicates whether the user is authorized to view this feature type. Type: boolean.

Exception reporting

When the WFS feature type 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" 
<ows:Exception exceptionCode="{the exception code}">
{the error message}

For GeoJSON, the response will be:

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