[Qgis-user] Mobile GIS

[Miguel Montesinos]

Hi Phillip and Noli,

We have developed the application Phillip points out. It doen't support
those features so far, but if you like to use it as a base, we are ready
to collaborate in order to support the creation of geometries (point,
polyline, polygon) from the GPS (or hand-based), or some other vector
capabilitites.

I've recently acquired my third Android phone, and I'm sure that Android
projection is going to be really impressive (it's right now, as a matter
of fact).

It will be great to extend the community of users and developers of this
application.

Regards,

Miguel Montesinos
