[Digikam-users] Geocoding and digiKam

[Gilles Caulier]

Hi Dimitri,

Few month ago an user report to bugzilla that digiKam must take a care
about the precision of GPS info embedded in Exif. Typically, the GPS device
need to be well synchronized with the satellite to have enough precision of
position measurement. This prevent wrong map position of image when
precision is not enough.

This is debated in this file : https://bugs.kde.org/show_bug.cgi?id=326406

Look also if this file is relevant of your problem :
*https://bugs.kde.org/show_bug.cgi?id=353458
<https://bugs.kde.org/show_bug.cgi?id=353458>*

So there is another Exif GPS tags to add to said to digiKam to handle the
information.

Look in image metadata if you don't miss the references of lat and long
info :

Exif.GPSInfo.GPSLatitudeRef


Exif.GPSInfo.GPSLongitudeRef



Look in code, it's not too complex to understand :

https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/libs/dmetadata/metaengine_gps.cpp

If these 2 tags are not present, the GPS info is not decoded.
