Django GeoJSON Tiles

A simple Django view to serve GeoJSON tiles from a GeoDjango model

Description

The view will return a GeoJSON FeatureCollection for each tile. Each feature corresponds to a row of the model.

Setup

pip install django-geojson-tiles

Add the following to your urls.py:

from geojson_tiles.views import GeoJSONTile
from your_app import GeometryModel

urlpatterns = patterns('',
    url(r'^your_endpoint/(?P<z>\d+)/(?P<x>\d+)/(?P<y>\d+).json$',
        GeoJSONTile(GeometryModel, geometry_field='geometry_field', trim_to_boundary=True))
)

Notes

1. geometry_field='geometry_field' specifies the geometry to use in the feature. If no geometry_field is specified: the first GeometryField in the model's field set is used.
2. trim_to_boundary=True will result in GeoJSON tiles with geometries trimmed to the tile boundary
3. properties=[...] can be used to limit the feature's properties that are serialized
4. properties={'field_name': 'property name'} will limit the feature's properties and map field names (keys) to property names (values).
