The WMS service allows cartography to be downloaded in real time online.

To this end, it is necessary to connect to a server and indicate the layers, the coordinates' system and the image format (in the current TcpGPS version only JPEG images are allowed). The programmes makes consultations of these elements by means of the following screen:

    

 

The upper left-hand side shows the list of WMS servers. By default, those used most in Spain are shown, but it is also possible to add other new ones and edit the existing ones.

 

 

    

 

 

The CRS list contains the EPSG codes (See section Settings > Geodesy) which supports the server. This code must coincide with the one which has been selected in the project properties. By pressing the  button on the right-hand side of the list, a message is shown with the coordinate limits for the selected system. This additional data is solely for informative purposes as the programme automatically downloads the cartography corresponding to the current GPS position.

 

            The View Map button provides a preview of the cartography with the data selected.

 

       

 

To deactivate this type of cartography in the different data acquisition options, None must be selected from the WMS Server list.
