Snapping for Editing

The Service API also supports snap layer for editing. Therefore it is necessary to configure snapping for a certain edit layer.

 

icon_comment

Snap layers in general are not supported from the Service API. You can only use snap layers within edit layers.

 

The only additional parameter for snapping is:

snap_profile_id

The value of the snap_profile_id can be found in the XML of the project configuration (see screenshot below).

 

Sample request for snapping for a certain edit layer would be:

../synservice?project=World&snap_profile_id=124040

 

The response of the Service API includes the snap points node with a list of all snap points for the requested layer.
