The fact that Upload Wizard doesn't allow effective categorization is obviously an UploadWizard issue (one of many its serious deficiencies). If UploadWizard will use some better method how to enable to go through the category tree, it needs not to use just HotCat.

As I know, this function is intentional and useful. Topical categories should be never added through templates but should by manageable by Hot-Cat and Cat-a-Lot, category-renaming bots etc. if needed to move the files to more special or more suitable category etc. Categorizing through templates should be used only as tagging for technical flat categories. The linked example was really not properly categorized. It is not categorized by place (Arad) nor by the subject (theatre) nor in the category tree of Romanian heritage monument but only in some flat categories. It's quite OK that bots or UploadWizard marks such files as uncategorized.

Sure thing, it's easy enough to add that other field. Could you please provide a sample photo that has it? It would make testing easier for us.

I'd be very careful about that.

According to exiv2.org, Exif.GPSInfo.GPSTrack is not for the camera heading but for for the direction the GPS sensor was moving. Note that with GPS alone, it's impossible to determine the actual camera heading, you'll need an electronic compass for that (the "GPS" in Exif.GPSInfo.GPSImgDirection is misleading). If your camera doesn't have an electronic compass (and as far as I can see the DSC-HX400V doesn't), direction of movement may be the next best thing, but it may be off 90° if you were shooting sideways out of a moving car or even 180° if you were walking backwards/away from the subject before taking the shot!

Even if you were walking up straight to the subject the heading may be off: If you stand still for a while to take the shot, the GPS unit is constantly re-evaluating its position and because of errors of measurement the recorded position will slightly change over time, which may mean that the heading between the last two recorded points has nothing to do with your actual (non-) movement (this depends on how the device determines the heading, e.g. some may notice that you are not actually moving and hence not record a heading at all).

I think it's better to have no heading at all than one that is likely to be wrong.

PS: found a better source for the meaning of the tags: official CIPA document
PPS: Thanks @Gilles btw for your work on this!
