below are the screen shots. The first as created in Viking, then Google and last LR4.1

Viking is a GPS Data and Topo Analyzer, Explorer and Manager. I use it to create tracks from places where I've been, where no roads are marked in Google. Amongst others, it uses OpenStreetMap (Cycle in my case). I want to GPS tag older photos, where I know the tracks, but as I said, not shown on the map.

I could of course use other software to tag photos individually, but I wanted to use LR's feature to make things easier.

Here is the track log

It wouldn't accept the gpx file, even though I changed the extension to txt and png

Unless absolutely necessary, I don't really want to open another account somewhere. Last year I was able to send through Rapidshare, but now I would have to create an account.

Anyway, the above gpx was actually converted from Google. The attached one is from Viking. Slightly different result, but basically the same.

I was actually going to manually add the photos to the track, but I suppose LR is not able to do so. I have to use other software that is able to do so. I have tried GeoSetter, which can do what I want. My aim was to use just one program.

At the noment I use Adobe Bridge, CS5 and LR4, plus a few other programs. The workflow is getting too complicated, it is easy to make mistakes somewhere along the line and also time consuming

please refer to post No. 4

having already tagged about 5000 photos in LR, I am aware of it's main purpose. However, I have several hundred photos from mountaineering, where the roads or tracks are not shown on Google maps. They are also not visible from satellite view. They are shown on OpenStreet Cycle map. Since LR will only show Google maps, I can't find the correct positions.

So I thought of creating the tracks externally and assigning the GPS tags in LR. The reason I thought that this might be possible, is that the created tracks show correctly in Google Maps.

Anyway, thank you all for trying to help.

yes, it is strange. I've also modified some tracks in Google on the weekend, as the track weaves in and out. It was quite easy to correct them, then saved the result. The first modification showed correctly in LR, but a subsequent modification produced the criss-crosses again. Pretty bad this time, as this was a 7 km track. On checking, the second modification had the time stamps removed, but the photos taken along this track still show the correct time. Every other program I have shows it correctly.

Unfortunately, I can't show this one...
