django-extended-ol

django-extended-ol is a Django app that extends the basic OpenLayers Widget.

• Custom WMTS base_layer with fixed resolutions

Quick start

1. Add "olwidget" to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       ...,
       "olwidget",
   ]
   

2. Configure olwidget in your settings.py, here's an example:

   OLWIDGET = {
       "globals": {
           "srid": 2056,
           "default_center": [2551470, 1211190], # optional
           "default_resolution": 18, # optional
           "extent": [2420000, 1030000, 2900000, 1360000],
           "resolutions": [250, 100, 50, 20, 10, 5, 2.5, 2, 1.5, 1, 0.5, 0.25, 0.125, 0.0625]
       },
       "wmts": {
           "layer_name": 'plan_cadastral',
           "style": 'default',
           "matrix_set": 'EPSG2056',
           "attributions": '<a target="new" href="https://sitn.ne.ch/web/conditions_utilisation/contrat_SITN_MO.htm'
             + '">© SITN</a>', # optional
           "url_template": 'https://sitn.ne.ch/mapproxy95/wmts/1.0.0/{layer}/{style}/{TileMatrixSet}/{TileMatrix}/{TileRow}/{TileCol}.png',
           "request_encoding": 'REST', # optional
           "format": 'image/png' # optional
       }
   }
   

3. You can now use WMTSWidget in your gis forms:

   gis_widget = WMTSWidget
   

4. You can also use it in your admin.py:

   from django.contrib.gis import admin
   from .models import YourGeomModel
   from olwidget.admin import WMTSGISModelAdmin
   
   admin.site.register(YourGeomModel, WMTSGISModelAdmin)
   

5. Start the development server and visit the admin.
