Publishing maps to OGC API - Maps
|
|
=================================
|
|
|
|
`OGC API - Maps`_ provides geospatial data as web maps.
|
|
|
|
To add data to pygeoapi, you can use the dataset example in :ref:`configuration`
|
|
as a baseline and modify accordingly.
|
|
|
|
Providers
|
|
---------
|
|
|
|
pygeoapi core feature providers are listed below, along with a matrix of supported query
|
|
parameters.
|
|
|
|

`MapScript`,✅,✅
|
|
`WMSFacade`_,✅,✅
|
|
|
|
|
|
Below are specific connection examples based on supported providers.

Connection examples
|
|
-------------------
|
|
|
|
MapScript
|
|
^^^^^^^^^
|
|
|
|
`MapScript`_ is MapServer's scripting interface to map rendering.
|
|
|
|
To publish a map via MapScript, the path to data is required, as well as
|
|
the layer type (`options.type`). To style the data, set `options.style`. If
|
|
no style is specified, the layer will be rendered with defaults.
|
|
|
|
MapServer layer types (`options.type`):
|
|
|
|
- `MS_LAYER_POINT`
|
|
- `MS_LAYER_LINE`
|
|
- `MS_LAYER_POLYGON`
|
|
- `MS_LAYER_RASTER`
|
|
|
|
Currently supported style files (`options.style`):
|
|
|
|
- OGC Styled Layer Descriptor (SLD)
|
|
- MapServer CLASS includes (i.e. file snippets with CLASS definitions)
|
|
|
|
.. code-block:: yaml
|
|
|
|
providers:
|
|
- type: map
|
|
name: MapScript
|
|
data: /path/to/data.shp
|
|
options:
|
|
type: MS_LAYER_POINT
|
|
layer: foo_name
|
|
style: ./foo.sld
|
|
format:
|
|
name: png
|
|
mimetype: image/png
|
|
|
|
WMSFacade
|
|
^^^^^^^^^
|
|
|
|
To publish a WMS via pygeoapi, the WMS base URL (`data`) and layer name (`options.layer`) is
|
|
required. An optional style name can be defined via `options.style`.
|
|
|
|
.. code-block:: yaml
|
|
|
|
providers:
|
|
- type: map
|
|
name: WMSFacade
|
|
data: https://demo.mapserver.org/cgi-bin/msautotest
|
|
options:
|
|
layer: world_latlong
|
|
style: default
|
|
format:
|
|
name: png
|
|
mimetype: image/png
