|
|||
This extension contains plugins that add geospatial capabilities to CKAN.
|
||||
The following plugins are currently available:
|
||||
|
||||
* Automatic geo-indexing and spatial API call (`spatial_query`).
|
||||
* Spatial model for CKAN datasets and automatic geo-indexing (`spatial_metadata`)
|
||||
* Spatial search integration and API call (`spatial_query`).
|
||||
* Map widget integrated on the search form (`spatial_query_widget`).
|
||||
* Map widget showing a dataset extent (`dataset_extent_map`).
|
||||
* A Web Map Service (WMS) previewer (`wms_preview`).
|
||||
|
||||
All plugins except the WMS previewer require the `spatial_metadata` plugin.

When enabling the spatial metadata, you can define the projection
|

in which extents are stored in the database with the following option. Use
|

the EPSG code as an integer (e.g 4326, 4258, 27700, etc). It defaults to
|

4326::

ckan.spatial.srid = 4326
|
||||
|

If you want to define a default map extent for the different map widgets,
|
||||
(e.g. if you are running a national instace of CKAN) you can do so adding
|

this configuration option::
|

ckan.spatial.default_map_extent=<minx>,<miny>,<maxx>,<maxy>
