Sorry if X-posting occurs : I hadn't registered to the list before I sent this and the "The original message you sent to the newsgroup will be posted within ten minutes" is now over an hour and a half old. Trying again.
================ 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 ?
