CSW
What is a CSW
A Catalogue Service for the Web, is a standard in where one can search for datasets in an online Catalogue. To search for data, the user enters a keyword to search on. All the datasets that contain the keyword in their metadata, will pop up. A dataset can then be downloaded in different (geo) data formats. The CSW standard is defined by the OGC, the Open Geospatial Consortium.
How to insert a CSW URL to the Engine
There are already two CSW provided by default to load data from. These are already used by the Engine, among other datasets, to create a new project with.
- BAG: the base registration for Addresses and Buildings in the Netherlands.
- BRP: Gewaspercelen, a Dutch dataset containing the type of crops.
It is also possible to provide another WFS. This WFS must conform to the following requirement before it can be loaded properly into the Engine:
- The WFS must have either GML3 or GeoJSON as output format.
The WFS can be loaded in the Engine by using the Geo Data Wizard. Choose the second option: "Loading data from a Feature Service".
In the next step, you will be asked to provide a name and the URL for the WFS. If the WFS is published through ArcGIS server (Arcgis is then part of the URL), choose ESRI_JSON as output type, otherwise choose WFS_JSON.
- Choose a name for the WFS
- Provinde the URL of the WFS (the GetCapabilities part can be omitted)
- If the WFS is published through ArcGIS server, choose ESRI_JSON, otherwise choose WFS_JSON
