No, the GPX driver of GDAL which is used by Qgis for Save As does not know how to handle polygon geometries, and throws an error. But you can convert the polygon into a line geometry using Vector->Geometry-Tools->Polygon to line, and export the resulting new shapefile to GPX. Most probably you want to add FORCE_GPX_TRACK=YES in the layer creation ...

You may use GPSBabel. garmin GDB format is supported (see this page). Something like that should work: gpsbabel -i gdb -f file.gdb -o gpx A short batch file to loop through and convert all files in a directory: for %%f in (x:\garmin_data\*.gdb) do ( gpsbabel -i gdb -f "%%f" -o gpx -F "x:\gpx_data\%%~nf.gpx" ) The first -f is the input file and ...

To elaborate on HasT's answer, use GPSBabel to translate the GPX file to another format; I prefer to use CSV which appears as "Universal csv with field structure in first line" in GPSBabel's format dropdown. Then in QGIS make sure you have the Add Delimited Text Layer plugin enabled and use it to add your new csv file to your map.

One option is to use QlandKarte GT. This is free/open-source software, available for Windows, OS X, or Linux. To reference the map, you can go to map menu -> Edit/create map. Then follow the steps convert the map into a GeoTIFF. Then create a map collection from that. Go to map menu -> Select sub map, and select the tiles in your map. Choose the selected ...

Quantum GIS has a plugin "Garmin Custom Map" for the purpose you want: http://hub.qgis.org/projects/garmincustommap You can get it via the standard python plugin repository. I have not tried it myself, because my own (old) Etrex can not read custom maps. Georeferencing is installed by default with Quantum GIS, and you can add selfmade vector overlays or GPX ...

When I worked for Navigon the way we accessed the filesystem on the devices which were running Windows Mobile 5 was to put a text file with a particular name on the root of the SD card / USB, and it had a weird name like win.reg or something like that, and plugging it in would give you a windows file explorer instead of the standard device boot sequence / ...

Since your track is NOT a polygon, but rather a line, I think there's no way around manually editing the line to snap the endpoints to the exact same location. So: Once you're downloaded the gpx file from the GPS, do "Save As..." to save it as a shapefile. Now load that shapefile, and start editing. Be sure snapping is setup correctly (Settings-> Snapping ...

etrex 20 & 30 have microSD™ cards - you can read directly from the card from QGIS. Note: Garmin Connect™ compatible (online community where you analyze, categorize and share data) so you can upload it then download the data to to view in QGIS.

For etrex 20 & 30 (but not the 10) see the compare guide: https://buy.garmin.com/shop/compare.do?cID=145&compareProduct=87774&compareProduct=87771&compareProduct=87768 (see custom maps compatible) Garmin have free instructions on how to use Google Earth and your custom images (scanned topographic route maps) in this case and loading it to ...

One option is to create a KML overlay. I can't specifically remember how to do it manually. Basically, it's a zip file with an internal folder structure to house images. There's also an XML file involved which maps the images to the project space. I collaborated on an ArcExplorer plugin to do the heavy for this. I realize you're on a Mac and this isn't ...

Garmin Products require JPEG format You Can use Google Earth to Create Custom Maps for Garmin "Garmin Custom Maps require your map be saved in JPEG format. If your map is printed, scan the map at an appropriate resolution¹, and save the image as a JPEG. If your map is electronic, such as a PDF, it may require conversion using GIMP or another ...

I suspect that you have a serial connection if you are connecting into the back of the computer and have a 4 pin connector on the gps. I would normally recommend DNR Garmin for this task however there appears to be major issues in Minnesota so will be required to find some other software. I would recommend Quantum GIS (aka QGIS) since they have a gps ...

Correct. With the GPSMap 78 in particular you can no longer use the "Track" or "Waypoints" menus to download data. The GPS is now visible as an "external" drive. So instead you have to go to File -> Menu -> Load From -> File Navigate to the GPS and select the GPX file. (Change the File Type dropdown option to GPS Exchange Format (*.gpx) first)

Within DNR Garmin, you connect the GPS, then make the Track menu option active and select Download. You need saved tracks to begin with and has been used on several varieties of etrex gps units. EDIT See this thread also.

It looks like someone has already found a way to play with the Garmin GPSmap 60 in a UNIX environment using GPS Babel (as Darren Cope suggested). Another option is trying to use Garmin software: Garmin Communicator browser plugin, Garmin Connect web service, or the Garmin Device Interface SDK

The following configuration works for me with MacOS 10.6.8 QGIS 1.7.2 and the Garmin 60CSx: Setup the 60CSx to use Garmin Serial Data Format before you connect to the computer. Press the MENU key twice to open the main menu. Use the rocker button to highlight the Setup icon and press ENTR button. Use the rocker button again to higlight the Interface icon ...

@Gray, first, upgrade to QGIS 1.7.4-4, if you can. Transferring data, via the GPS Tools, leverages the GPSBabel tool. When debugging a GPS (that appears to not be working with QGIS) it is best to start with GPSBabel and see if it connects and downloads data in .gpx format, which can be added to QGIS via the GPS Tools directly. You're in luck, many users of ...

Enable on-the-fly reprojection in project settings. Make sure the Garmin waypoint layer is set to WGS84 in layer properties and the topocard layer is set to Web Mercator ("Google Mercator"). If you still have the OpenLayers layer loaded, you might experience problems if you try to set the project CRS to anything else but Web Mercator.

I guess it depends where you are located, as the precision of the etrex 30 will depend on how many satellites (GPS and Glonass) you can see. As far as I know (but I might be wrong), the Glonass constellation is not so dense over northern America, but better in Asia and Europe. From my experience the sensitivity of the etrex30 is much much better than the ...

You can see a comparison table between the two on the Garmin website. The eTrex 30 supports GLONASS in addition to GPS, which (at least in theory) means more satellites and more accuracy.
