I want to export the boundaries of a parcel to my GarminMap 60CSx. I downloaded a parcel map from the county, and I want to use it to walk the perimeter.
Does the .gpx format support polygons? Or is there some other way?
I'm on Mac, using QGIS 1.7.4.
Answer
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 field, and check Surpress attribute creation.
And make sure the export CRS is EPSG:4326, that is WGS84 latlon.
