Hi All,

I'm new to this list !  I watched the video showing how to use the GPS 
Tools plug-in to download waypoints from a GPS receiver and upload a 
route (http://qgis.org/flash/flashwrapper.php?filename=gpx_demo.swf) and 
then I tried it with success (except it was a bit of a pain to get 
Windows to see my GPS receiver to begin with).  I have a couple of 
questions about uploading data into a GPS receiver for which I haven't 
found much documentation.

First, when one uploads a route, one sees a number of 'RPT*' points that 
correspond to the vertices of the route.  Is there a way to see a line 
connecting those points in the GPS ?  Is there a setting I missed in the 
GPS Tools plugin ?

Second, one of the use cases we have here is to shove some very specific 
large scale cartographic information of small areas that people are sent 
in the field to check for their validity.  For example, someone does a 
photo-interpretation of wetlands for an area.  We digitize the result 
and we use a GIS to superimpose relevant layers (roads, rivers, etc.) 
with adequate symbology.  Once that is done, we make an image (.IMG) out 
of it and upload it to the GPS.  The result is that a small square shows 
up and as one zooms in on sees the image.  Someone in the field is 
charged with highlighting delineation differences as waypoints.  Of 
course, it's a static graphic plane so we can't query objects on it, but 
the purpose really is to give a close-up geaographical picture of a 
small area without having a detailed layer for a whole continent.

Our current procudure for this second point involves two pieces of 
software :

- GPSMapEdit (http://www.geopainting.com/en/) to put the map together 
with labels and symbology, which results in an uploadable IMG file

- MapUpload (http://mapwel.biz/down.htm) which allows up to upload the 
IMG files to a Garmin only GPS receiver

Two issues I have are : 1) MapUpload only works for Garmin products and 
2) both those software packages are non free, one being freeware and the 
other providing some access to the source but with pretty stringent 
licensing requirements.

Is there a way I can do this with QGIS ?

TIA for pointers,

Yves Moisan
