Django speaking WFS 2.0 (exposing GeoDjango model fields)

Project description


Django speaking WFS 2.0 to expose geo data.


  • WFS 2.0 simple implementation.
  • GML 3.2 output.
  • GeoJSON export support.
  • Extensible view/operations.
  • Uses GeoDjango queries for filtering.
  • Uses Django template engine for rendering XML (might become streaming lxml later).


Create a model that exposes a GeoDjango field:

from django.contrib.gis.db.models import PointField
from django.db import models

class Restaurant(models.Model):
    name = models.CharField(max_length=200)
    location = PointField(null=True)

    def __str__(self):

Write a view that exposes this model as a WFS feature:

from gisserver.features import FeatureType, ServiceDescription
from gisserver.types import CRS, WGS84
from gisserver.views import WFSView
from .models import Restaurant

RD_NEW = CRS.from_string("urn:ogc:def:crs:EPSG::28992")

class PlacesWFSView(WFSView):
    """An simple view that uses the WFSView against our test model."""

    xml_namespace = ""

    # The service metadata
    service_description = ServiceDescription(

    # Each Django model is listed here as a feature.
    feature_types = [
        FeatureType(Restaurant.objects.all(), other_crs=[RD_NEW]),

Use that view in the URLConf:

from django.urls import path
from . import views

urlpatterns = [
    path("/wfs/places/", views.PlacesWFSView.as_view()),

You can now use http://localhost:8000/wfs/places/ in your GIS application. It will perform requests such as:

By adding &OUTPUTFORMAT=geojson to the GetFeature request, the GeoJSON output is returned.

Standards compliance

Currently, the following 3 methods are implemented:

  • GetCapabilities
  • DescribeFeatureType
  • GetFeature with bbox and pagination support.

This is sufficient to show results in QGis. The unit tests validate the output against WFS 2.0 XSD schema.

Some parts for conformance to the "WFS simple" level are not implemented yet:

  • GetPropertyValue
  • ListStoredQueries
  • DescribeStoredQueries
  • Certain parameters:
    • Filtering: filter, filter_language, resourceID, propertyName, aliases.
    • Remote resolving: resolve, resolveDepth, resolveTimeout.
    • Output rewriting: namespaces.
    • Some GetCapabilities features: acceptFormats and sections.
    • Using GetFeature with only the StoredQuery action.

Filtering is high on the TO-DO list.

Low-prio items:

Anything outside WFS simple could be implemented, but is very low on the todo-list:

  • The methods for the WFS basic, transactional, locking and inheritance conformance classes.
  • HTTP POST requests.
  • SOAP requests.
  • Other protocols (WMS, WMTS, WCS)
  • Other output formats (shapefile, CSV, KML, GML 3.1) - but easy to add.


When you follow the source of the WFSView, WFSMethod and Parameter classes, you'll find that it's written with extensibility in mind. Extra parameters and operations can easily be added there. You could even do that within your own projects and implementations.

The Makefile gives you all you need to start working on the project. Typing make gives an overview of all possible shortcut commands.

Why this code is shared

The "datapunt" team of the Municipality of Amsterdam develops software for the municipality. Much of this software is then published as Open Source so that other municipalities, organizations and citizens can use the software as a basis and inspiration to develop similar software themselves. The Municipality of Amsterdam considers it important that software developed with public money is also publicly available.

This package is initially developed by the City of Amsterdam, but the tools and concepts created in this project can be used in any city.
