>> also http://www.geofoto.ch/geophotomap/ (currently does not work in all
>> browsers, need to fix a few things). Should work in Firefox.
>>
>> Now my question:
>>
>> These destination EXIF metadata needs to be set by hand. Digikam already
>> has the map view of where the photo was taken. Would it be possible to
>> enhance Digikam to allow the edition of the GPSDestination metadata.
>> This concerns the following EXIF tags:
>>
>> GPSDestLatitude
>> GPSDestLongitude
>> GPSDestLatitudeRef
>> GPSDestLongitudeRef
>> GPSDestBearingRef
>> GPSDestDistanceRef
>> GPSDestDistance
>>
>> Some GPS tagger device also record bearing data (electronic compass).
>>
>> Based on the size of the photo sensor and the fov one can then draw a
>> viewing angle like in
>> http://www.carto.net/neumann/temp/geophoto_view_angle.png
>>
>> I am not a developer but I would be willing to pay a digikam developer
>> to work on the following:
>>
>> 1. ability to edit all of the GPSDestxx EXIF data listed above - both
>> interactively in the map, but also based on numeric values (line input
>> widgets)
>>
>> 2. ability to draw the viewing angle on a map like shown in
>> http://www.carto.net/neumann/temp/geophoto_view_angle.png
>>
>> Is there a digikam developer out there who would like to work on these
>> features if I would fund the work?
