The geospatial data on this site can be accessed using Open Geospatial Consortium (OGC) services:

• CSW services: Catalogue Service for Web. A CSW service publishes collections of descriptive information (metadata) about geospatial data.
• WMS services: Web Map Service. A WMS service delivers a digital image (such as PNG, GIF or JPEG) of spatially referenced raster data (e.g. satellite photo).
• WFS services: Web Feature Service. A WFS service delivers a digital image (such as PNG, GIF or JPEG) of geographic feature (vector) data (e.g. a road map).

Explainations on how to use OGC services can be found on the information page.
