Thank > you very much Klaus for your document. As you say there are many ways to convert GPX files to something more "GIS" friendly. In fact it's quite desirable as I understand GPX as something "raw", your starting point to derive data. OGR is a well known library that understands GPX[5] so you can easily convert from this format to many others[1] using the ogr2ogr utility program[2]. Here there is a cheatsheet to have at hand[3]. OGR can be installed on Ubuntu/Debian from the "gdal-bin" package. In Windows you can use the OSGeo4W[4] distribution.
