How to use geolocation?

[John Stumbles]

I'm trying to understand the geolocation function. I'm assuming it
should allow you to assign geographical latitude and longitude
coordinates to images, similarly to the way one can apply them to one's
videos on YouTube.

If I select the geolocation icon on the right hand sidebar I get a map
of the world as seen from space with 'AMERICA' 'AFRICA' etc marked on it
and, below that 'Altitude:' 'Latitude:' 'Longitude:' and 'Date:' (all
blank) and a row of buttons below; but all this is greyed out and
nothing seems to do anything.

If I select the 'Map' icon on the top menu bar I get a map of part of
Holland. I have a row of buttons at the bottom like those in the sidebar
but these are in colour and my 'Map settings' button gives me a menu:
Google maps / Marble Virtual Globe (currently ticked) / Atlas map
(ticked) / Open street map ...etc. I can drag the map across to roughly
the location I wish to apply to my pictures but it only shows towns a
few tens of kilometres apart, and there seem no way to associate the
location with pictures.

If I select an image, or images, in my Thumbnail view, and choose menu
Image -> Geolocation I get a pop-up titled "Geolocation - digiKam" with
another low-resolution map, but I can search for a specific location. I
can then select image(s) in a pane at bottom-left of this pop-up window
and I would guess that pressing 'Apply' should mark the selected images
with the coordinates of my chosen location. But the Apply button doesn't
seem, visibly, to do anything and when I 'Close' the Geolocation pop-up
window and go back to my Thumbnails view in the main dK window I can't
see any difference in the images I've tried to tag e.g. the
right-sidebar geolocation window is still a globe view, greyed out.


I've tried the digiKam help page but that shows the geolocation window
in colour displaying a map of a smaller portion of the planet the
hemisphere mine is showing, and doesn't say how to get to that sort of
display.


Any help would be much appreciated!

I've just worked it out recently...

Select your photos to be geotagged in the thumbnails view.

Call Image->Geolocation.

Your chosen photos are listed bottom left.
Choose a map top left, OSM or Google..., you can zoom in very deep...
You can search a location (city etc) inside the Search-Tab at the very right side of the window, then correct the map view to your desired photo location.
Then go back to the Details Tab.
Select one or more photos bottom left and drag-drop them on the map to the locations they where taken. The locations will be taken from the map.
!!! You see the adopted location for a particular photo in the folders top right _only_if_  you _double_ click the thumbnail bottom left and the photo will be shown bottom right. Then you get displayed its location top right and can edit it directly.
After editing directly a location for a photo then click the button APPLY in the middle between location fields and displayed photo.
With the right mouse click on a thumbnail you can also copy-paste locations between photos.

Don't forget to apply the changes at the very end :)

Back again in the thumbnails view open the Geolocation from the right side of the main window and select successively the thumbnails you've just geotagged. The shown map will jump each time to the right assigned location. Gorgeous!

BTW... Should you want to geotag and arrange the photos along a gps track from a gps device, see the GPSCorrelator Tab of the Image->Geolocation-Tool.

Have fun!

And... Kudos to the programmers!

If only I could lock a desired zoom level on the map... see my own question yesterday... ;)

Sorry for resurrecting this thread, but I believe this will save others' time, should Google also lead them here.

If your digiKam does NOT have a "Geo-location" item in the Image menu, as mine didn't, try installing kipi-plugins (if using a Debian-based distro). It contains the GPSSync plug-in which is necessary to add geo-location data. All other interface buttons are only useful to see already existing data, and fiddling with them will not help.
