How to create osm file from gpx kml or kmz file.
It is my data from Google Earth.Earth.
*Additional info / update:*
First issue, I "misspoke". It is my data that I store in Google Earth. My point was that the data will be exported from GE to the above mentioned file formats. I own the data. I created all of the data without violating the GE terms of service. I only store it in Google Earth so that I can see where I have been relative to their maps. This has taken me 7 or 8 years to accumulate this data.
Thank you for pointing me to a web page! It has several possibilities and I will look them over to see if I can use them.
My objective is to take these many tracks that I have collected and put them all on my Garmin etrex 20 for my personal use. The etrex has a limit of 200 tracks so they won't all fit on it. If I could convert these tracks to a .img file (a map file) I could easily load all of the tracks onto the etrex without any problem and they would show up on the etrex map. The only reason I went in the direction of osm was because I found a page on YouTube that explained how to get from osm to img. I can't seem to find anything about going from kml/kmz/gpx/gdb to img.
Also, if going to osm means I would have to share my data globally then I wouldn't be see that as an option.
Thank you for your help! Now that you know all the facts, if you can help me with any additional information I would be very grateful. Thanks!
