A Source is a definition for where data was or can be retrieved from.
A Source's primary property is the url it is directed to. The data found at the url's endpoint is then interpreted based on the Service Type the Source is configured as.
When a Source is defined, it can be used as a source for the retrieval of data, either manually via the Geo Data Wizard, or automatically via a Geo Plugin.
Service Type
Depending on the external source or service, data should be interpreted in a specific way and can be used in specific ways. This means that for any given Source, an appropriate Service Type must be configured.
The following Service Types are available:
| Type | Used for |
|---|---|
| BGT_GML | |
| CYCLO_IMAGE | |
| ESRI_IMAGE | Connection to an ESRI-hosted WMS for image data. |
| ESRI_JSON | Connection to an ESRI-hosted WFS for vector data which supports providing data in a geojson format. |
| GEOJSON | GeoJSON files, such as those hosted on the GeoShare |
| GEOTIFF | GeoTiff files, such as those hosted on the GeoShare |
| I3S | |
| OSM | |
| WCS_TIFF | Connection to a WCS for grid data which supports providing data in a GeoTIFF format. |
| WFS_GML | Connection to a WFS for vector data which supports providing data in a gml-conformant XML format. |
| WFS_JSON | Connection to a WFS for vector data which supports providing data in a GeoJSON format. |
| WMS_IMAGE | Connection to a WMS for image data which supports providing data in a png or jpeg format. |
