I thought it was out of date (I saw something about gzip the xml-rpc,
while I know you are dropping it).

How will you group a list of segments which are part of the same
street? Is there a grouping option or simply the same name should be
given to all segments?

Take the GPS traces, split them to segments (by detecting turns,
detecting intersection, etc') and add them as road segments to the
database. If the database already contains a segment near the one we
want to add, do some merging.

You could just do incremental backups and point-in-time backups of the
postgres DB. But the idea is not to replace the applet, but to allow
some administrator more control over the database with already
existing tools. You also get free wms, wfs, interfaces.

My first goal is to write a simple server which will transfer the GPS
traces to road segments and insert into the DB. I'd like to get some
information about your applet's DB scheme so I can see how everything
could fit together.

Ehud.
