Thanks for replying. We as a team on six are working on a project which
involves developing a location based service. One of the key product
functions of this service is the ability for the user to reach a location
using open street map. Therefore, for this purpose we are looking at Gpsmid

we have some specific questions on GpsMid and perhaps would ask them in the
GpsMid forums at sourceforge.

Regards & Thanks
