I have been away form my PC for a week. Last night I did a few edits and all was good. I had 8 (ish) separate maps that had a serious amount of data input (Showing my rail travel history) that has taken me a LOT of effort.
This morning I have logged in and literally everything has gone and I am back where I was at the very very start of my playing with this amazing tool
I have been checking on every edit that I had save points that were up to date.
I can only guess, but you probably used the iD-Editor?
As far as I understand you, you started changes in it but did not upload them.
Since the iD Browser only runs in the browser, the changes are not cached there when you exit the browser.
This is similar to a text document that you start in Word, for example, and then exit Word without saving. Then all your text is gone too.
Your changes are lost forever, I’m sorry to say. It is always advisable to upload changes to OpenStreetMap in smaller packages on a regular basis. Smaller packages means about 25-50 changes and also keep the area of changes as small as possible. So for example don’t add a cafe in Canada and in the same set of changes add a bank in India.
What tool did you use to do your edits with?
Did you ever save what you did?
Are you aware that OSM is a tool to edit/create the map as it is “on the ground”, meaning that you cannot use it to make a diary of your own railway travels?
What is your OSM user name?
Hi I am using umap openstreet map
I saved every few minutes and had filesa as large as 50mb on one map, So I imported a lot of stuff using files from Brouter as gpx files and then also did hundreds of edits using the plotting tools / icons etc
