-Web Map Service (WMS), Web Map Tile Services (WMTS), and Web Feature Service (WFS) are the standard protocols of the [[http://www.opengeospatial.org/|Open Geospatial Consortium]] for serving, viewing, or editing georeferenced map images and geographical features over the internet or Intranet using platform-independent calls.+Web Map Service (WMS), Web Map Tile Services (WMTS), and Web Feature Service (WFS) are the standard protocols of the Open Geospatial Consortium for serving, viewing, or editing georeferenced map images and geographical features over the internet or Intranet using platform-independent calls.
  
-A WMS, WMTS serves georeference map data only. A WFS returns both spatial features and attributes. This makes it possible to use a WFS dataset for spatial analyses, attribute viewing, and if allowed to edit and update the dataset.+More information:

 +When loading web resources via a secured HTTPS connection, the website's Security Certificate must be available to the Java Runtime Engine used by Orbit. \\  
 +If the certificate is not known to the Java Runtime Engine, the following message is printed in the [[dev:technology:platforms:logfiles|Orbit logfile]]:

 +To use a Web-based resource a successful network connection to the providing server/service is required. \\ 
 +If no connection could be established, obviously Orbit will not be able to load the resource. Review the documentation below on how to check the connection from the local network to the web service.
  
 If a network connection is successful, but Orbit can't load resources, most probably the Orbit application is not allowed to get online/network access due to an internal internet security application (e.g. aXsGUARD Gatekeeper from Vasco).
