1. The GISsurfer web map is displaying a Gmap4 map. There is a problem with the q parameter. Gmap4 has been replaced by GISsurfer. Currently GISsurfer only supports the display of tracks in GPX files. KML and KMZ files are not (yet) supported. If you produced the Gmap4 link, it is recommended that you revise the link to use current GISsurfer syntax. GISsurfer documentation

There is a problem in the following row.

GISsurfer does not currently support KML or KMZ files. Support for those file types might be added in the future.
