Validate internal data structures (validate)

This filter can be used to check internal data structures for validity. The output of the filter is identical to the input, but if corruption is found a fatal error will be issued.

checkempty option

Check for empty input.

This option will cause a fatal error if there are no waypoints, no route waypoints and no track waypoints, i.e. the reader didn't produce anything.

debug option

Output debug messages instead of possibly issuing a fatal error.

This option will output verbose messages reporting the state of the internal data structures holding waypoints, routes and tracks. Detected problems will normally produce a fatal error, but with this option in effect no error will be thrown allowing continued processing.
