Currently the altitude is read only in the map module for images that already have it. For photos that do not have it you cannot set it , either manually, or form GPX file or from positionning the photo on the map
I can see the point of this and +1'd it as I agree that if the GPX or other GPS data is contained that it should be stored, and even like the getting the info from the approximate estimated elevation from the Map LR interacts with if the information is available.
Though my thoughts on it are also that most photos taken at a particular location are going to be at a single elevation unless you are either in a tall building or in an aircraft of some sort. The margin of error on consumer GPS's is also large enough that it also negates the exactness of the differences between the first floor vs. the third floor of a building typically.
Also.. does the elevation a photo generally matter under most circumstances?
Normally climb mountains and do many hiking trails. I take pictures during the tour and on the tops of the mountains. Integrate data altitude and coordinates if I find important. I like to see the altitude of the EXIF data when I visualize the image, especially because I have altitude data taken with a separate outdoor Garmin GPS, dedicated to keep all travel information. Later synchronize photos with the GPX file. I currently use a free software that performs the job well. If I can not sync photos with altitude data from my gpx file, I'll have to keep using my current software (GeoSetter).
Hi, actually I noticed it too. If you have a .xmp with altitude it is shown, otherwise if you import a gpx Lightroom matches latitude, longitude but not altitude..
Did they forgot it?
It would be useful to have it also.
LR 4.1 RC2 now lets you manually set the altitude of an image in the Metadata pane, and it gets properly written to the file's metadata. I haven't tested how it handles track logs.
