I have a number of .gpx files that I want to convert so that they can be viewed in ArcGIS. When I have tried using the ArcToolbox 'convert from GPS' tool, it has previously worked. Recently however, when I go through the process of converting the files from .gpx to .shp, no file is generated. The results log says that the Output Feature class is empty, but there is definitely data there, which can be viewed when you use a gpx viewer such as explorer. I have never had this problem before and don't know why ARC thinks the files are empty.
Any suggestions on why it's doing this and if there is another way that I can convert .gpx to .shp?
