Django Geotag

A tagging application in the spirit of 'django-tagging'. It allows to tag any django model with any number of Geodjango geometry fields such as PointField, PolygonField, etc...

Installation

For now, just place the 'geotag' directory into your django project directory.

Configuration and Usage

Add 'geotag' to your INSTALLED_APPS.

Register your models with the geotag app to add any number of geometric field types to your models.

Example:

import geotag

class Building(models.Model):
    ...
geotag.register(Building)

class Antenna(models.Model):
    type = models.CharField(max_length=50)
geotag.register(Antenna, name='site')
geotag.register(Antenna, type='poly', name='service_area')

The only required argument for the 'geotag.register' function is the django model class.

The other arguments are 'type' and 'name'.

'type' can be any of the following, defaults to 'point':

• 'point' for a PointField
• 'multi_point' for a MultiPointField
• 'poly' for a PolygonField
• 'multi_poly for a MultiPolygonField

'name' will become the name of the attribute for the geometry field. Defaults to 'location'

Then in the django shell

>>>from django.contrib.gis.geos import Point, Polygon
>>>from models import Building, Antenna
>>>building = Building.objects.create()
>>>building.location

>>>building.location = Point(0,0)
<PointLocation: SRID=4326;POINT (0.0000000000000000 0.0000000000000000)>
>>>antenna = Antenna.objects.create()
>>>antenna.site = Point(0,0)
<PointLocation: SRID=4326;POINT (0.0000000000000000 0.0000000000000000)>
>>>antenna.service_area = Polygon(((0,0),(0,10),(10,10),(0,10),(0,0)))
<PolyLocation: SRID=4326;POLYGON ((0.0000000000000000 0.0000000000000000, 0.0000000000000000 10.0000000000000000, 10.0000000000000000 10.0000000000000000, 0.0000000000000000 10.0000000000000000, 0.0000000000000000 0.0000000000000000))>
