User

An individual using the services.

Visualization

To obtain a visual representation of any data/products held within the platform - presented to the user within their web browser session.

Web Coverage Service (WCS)

OGC standard that provides an open specification for sharing raster datasets on the web.

Web Feature Service (WFS)

OGC standard that makes geographic feature data (vector geospatial datasets) available on the web.

Web Map Service (WMS)

OGC standard that provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases.

Web Map Tile Service (WMTS)

OGC standard that provides a simple HTTP interface for requesting map tiles of spatially referenced data using the images with predefined content, extent, and resolution.

Web Processing Services (WPS)

OGC standard that defines how a client can request the execution of a process, and how the output from the process is handled.
