252MB for 9 mapping trips (1-2 hours I think) Maybe I should take the quality down so I don't have JOSM running out of memory. You mentioned you don't need to knwo GPX traces because they'e on OSM. But note there may be many people like me that don't upload their traces, I just open them for use in JOSM and keep them local. I would love to geotag upload all my photos to flickr, but now there's a limit.

[OSM-talk] Straw Poll - Disk space used by OSM photos/audio
Hi After a conversation on IRC I started wondering what the total disk space was that people had used for their OSM photos (the photos of road signs, postboxes, etc. that many people use for mapping). I thought I'd conduct a straw poll on here to see what numbers came out. I'm not looking for particularly accurate numbers so there's no need to strip out photos that were blurred etc, but please actually check rather than guesstimating. Also if there's any other thing that you do as part of mapping that uses disk space you could give that number too (though please identify it separately), for example I'm giving the compressed audio that I often record as well as photos: Photos: 2.3G Audio: 187M Don't bother with GPX tracks though as these are obviously stored on OSM's servers already. I'm not intending to make use of these numbers anywhere really, I'm not particularly planning to create an OSM equivalent of flickr (though that could be pretty cool), I'm just interested to see what the number is :-) Feel free to just reply to me directly rather than polluting the list, I'll give it a few days or a week and post a total.

I'm not looking for particularly accurate numbers so there's no need to strip out photos that were blurred etc, but please actually check rather than guesstimating. Also if there's any other thing that you do as part of mapping that uses disk space you could give that number too (though please identify it separately), for example I'm giving the compressed audio that I often record as well as photos: Photos: 2.3G Audio: 187M Don't bother with GPX tracks though as these are obviously stored on OSM's servers already. I'm not intending to make use of these numbers anywhere really, I'm not particularly planning to create an OSM equivalent of flickr (though that could be pretty cool), I'm just interested to see what the number is :-) Feel free to just reply to me directly rather than polluting the list, I'll give it a few days or a week and post a total.
