GPX upload

Posted by daveemtb on 8 May 2009 in English (English)

Just finished uploading a whole stack of GPX files, after manually removing the point clouds from around my house and place of work. I really wish someone would write a neat app that could bulk process GPX files to do this, with a GUI. The ones I made public were just a small part of what I uploaded - 66 files.

You can remove point clouds with gpsbabel.

And even if you don't make the traces public they'll still appear in the GPS API, so someone requesting your area might still get your point clouds.

Yeah, that's why I had to filter them manually using JOSM - I was just meaning that some of us have a lot of files to work through.

What I was doing was removing the points around my house, place of work, etc. There's not necessarily a point cloud in any one file, but there are lots of useless points where the GPS is settling down, and put together they form a could that highlights "OSM contributor lives/works here" and pollutes the GPS database.

I have tried using GPS Babel, it seems you can only do what I want using the command line as the exclude option is not available in the GUI. I couldn't figure out what I needed to type to batch process hundreds of files. I think someone should write a tutorial on this on the wiki, or write a front end that makes it easy. Not all of us contributors are propeller heads! ;-)

If I could write code I'd do it myself, but my attempts in that direction have never got very far.

Actually I've got a script around which removes GPS entries in "private" areas (boxes specified by lat/lon of two corners). It's a Perl script, and not a GUI, interested?

That would be great actually, though if someone could put a gui front end on it I'm sure it would be welcomed by newcomers!
