RE: [gdal-dev] convert 2 shapefiles to a single GPX?
Now this I've got to try! The VRT file idea is intriguing. I didn't know it had this much flexibility...

Here's one solution : 1) create a directory, for example merge_shp 2) copy in merge_shp the shapefile that is going to be put in the waypoints layer as waypoints.shp (rename the .dbf and .shx accordingly) 3) copy in merge_shp the shapefile that is going to be put in the tracks layer as tracks.shp (rename the .dbf and .shx accordingly) 4) run ogr2ogr -f GPX merged.gpx merge_shp waypoints tracks (the order of the layers is important) A solution based on an OGR VRT file defining the two layers from the 2 shapefiles would also probably work.

I cannot merge 2 shapefiles with different geometry types. I could convert line shapegpx1 and point shape-gpx2 and then merge gpx2+gpx2-gpx3...

Hello, I don't know the answer to your question, but since GPX files are text files, it is very easy to merge two GPX files with a text editor. HTH !
