Soláthraíonn GeodJango roinnt réimsí foirme speisialaithe agus giuirléidí d'fhonn sonraí geolocálaithe a thaispeáint agus a chur in eagar ar léarscáil. De réir réamhshocraithe, úsáideann siad léarscáileanna OpenLayers faoi thiomáint, le bonn ciseal WMS a sholáthraíonn NASA.
\nChomh maith leis na rialt:ref: argóintí réimse foirm <core-field-arguments>, glacann réimsí foirme GeodJango na hargóintí roghnacha seo a leanas.

\ncineál_geomLink to this heading#De ghnáth níor cheart go mbeadh ort an tréith sin a shocrú nó a athrú ar chóir a chur ar bun ag brath ar an rang allamuigh. Meaitseálann sé ainm geoiméadrach caighdeánach OpenGIS.
\nmax_geom_collectionsLink to this heading#The maximum number of geometry collections the field accepts before\nrefusing to parse the input and raising a\nValidationError. This guards against crashes\nin the underlying GEOS library when parsing deeply nested\nGEOMETRYCOLLECTION input. It defaults to 198.
The limit is applied differently depending on the input format: for\nwell-known text (WKT) it bounds the nesting depth, while for well-known\nbinary (WKB and hex-encoded WKB) it bounds the total number of geometry\ncollections (both breadth and depth). As a result, the same value may\naccept a wide, shallow collection as WKT but reject it as WKB. For GeoJSON,\nthe limit is not applied at all, since GDAL parses that input type instead.
\nIncrease this value (or set to None) only if you must accept\nlegitimately deep geometries, since doing so reduces protection against\nfatal errors.

\nIs féidir leat tréithe giuirléid a rith ar an mbealach céanna le haghaidh aon ghuirléid Django eile. Mar shampla:
\nfrom django.contrib.gis import forms\n\n\nclass MyGeoForm(forms.Form):\n point = forms.PointField(widget=forms.OSMWidget(attrs={"display_raw": True}))\nBasegeometryWidget
This is an abstract base widget containing the logic needed by subclasses.\nYou cannot directly use this widget for a geometry field.\nNote that the rendering of GeoDjango widgets is based on a base layer name,\nidentified by the base_layer class attribute.
OpenLayersWidget
This is the default widget used by all GeoDjango form fields. Attributes\nare:
\nnasaWorldview

OpenLayersWidget and OSMWidget include the ol.js and\nol.css files hosted on the cdn.jsdelivr.net content-delivery\nnetwork. These files can be overridden by subclassing the widget and\nsetting the js and css properties of the inner Media class (see\nSócmhainní mar shainiú statach).
OsmWidget
This widget specialized OpenLayersWidget and uses an OpenStreetMap\nbase layer to display geographic objects on. Attributes are:

The OpenLayersWidget note about using external assets also applies\nhere. See also this FAQ answer about https access to map tiles.
To customize the base layer displayed in OpenLayers-based geometry widgets,\ndefine a new layer builder in a custom JavaScript file. For example:
\npath-to-file.js MapWidget.layerBuilder.custom_layer_name = function () {\n // Return an OpenLayers layer instance.\n return new ol.layer.Tile({source: new ol.source.<ChosenSource>()});\n };\nThen, subclass a standard geometry widget and set the base_layer:
from django.contrib.gis.forms.widgets import OpenLayersWidget\n\n\nclass YourCustomWidget(OpenLayersWidget):\n base_layer = "custom_layer_name"\n\n class Media:\n js = ["path-to-file.js"]\n
