Resources

The input data to be visualised can be any web-accessible resources, e.g. a URL to the file. It can be specified in the URL of the client call by adding a parameter for the URL of the resource and its MIME type or by using the "Add Resources" dialog from within Greenland:

	The "Add Resources" dialog is divided into three sections: Resources A tree view of already specified resources. The tree allows to navigate through the different levels within a resource, including the included datasets and on the last level the availabe visualizations. A visualization can get added to the map by selecting it and providing further required information in the Details panel. Resources are subdivided into WMS(-Q) Data Data served by a custom server backend (VISS) NetCDF-U GeoTIFF (+UncertML) Directly accessible vector data O&M vector XML O&M vector JSON For further details about the input data requirements see here. Add Resources A simple form that allows to add new resources by giving its full URL as well as the corresponding input type. After adding a new resource, it will directly appear in the resources tree view. Details This section gives information about a specific visualization of a resource. If a visualization requires further parameters, they can get set here. Clicking "Next" or "Add to map" finally creates the visualization.

The "Add Resources" dialog is divided into three sections:

Resources

A tree view of already specified resources. The tree allows to navigate through the different levels within a resource, including the included datasets and on the last level the availabe visualizations. A visualization can get added to the map by selecting it and providing further required information in the Details panel.

Resources are subdivided into

WMS(-Q) Data
Data served by a custom server backend (VISS)
- NetCDF-U
- GeoTIFF (+UncertML)
Directly accessible vector data
- O&M vector XML
- O&M vector JSON

For further details about the input data requirements see here.

Add Resources

A simple form that allows to add new resources by giving its full URL as well as the corresponding input type. After adding a new resource, it will directly appear in the resources tree view.

Details

This section gives information about a specific visualization of a resource. If a visualization requires further parameters, they can get set here. Clicking "Next" or "Add to map" finally creates the visualization.

Resources can also get specified in the URL of the client call by adding a parameter for the URL of the resource and its MIME type. For each supported MIME type, a special parameter value has been specified in addition to allow a direct specification of the resource URL in the HTTP request:

Parameter Value	Mime type	Notes
oc	application/xml	requires CORS support
json	application/x-om-u+json	requires CORS support
tiff	image/geotiff	using VISS
netcdf	application/netcdf	using VISS
rasterOM	application/vnd.ogc.om+xml	using VISS
om2	application/x-om-u+xml	requires CORS support
wms	wms	using Capabilities proxy
wms	ncwms	requires CORS support

Example for parameter url and mime:
