> If you need sample Pics for testing, ... please feel free to contact me!
Yes, we need samples. Either on some webspace, or via private mail.
Reading to database is the first step, and easy, implementing the UI is not so trivial.
Sorry for the late reply. Always in mind, just a lack of time :-/ ====================================== You will find geotagging examples here: https://www.gps-camera.eu/shop/geotagging-beispiele.html ====================================== Technical Examples ==> Geotagging-Fotos: ZIP-Datei mit Beispielen (JPEG) ==> Geotagging-Fotos: ZIP-Datei mit Beispielen (NEF) - Different Geotaggers on different Cameras - With/without compass - With/without indoor-buffer (some geotaggers mark GPS-EXIF from buffered data with "impossible" values for satellite count. GPS needs 3 (4) satellites to get a fix) - On ZIP is JPEG one is Nikon NEF (Raw) Outdoor-Examples ==> Geotagging-Testbilder für Programmierer (GPS/Kompass/Sonnenstand) - Geotagging examples with compass in the field - 360° shots from tower - different places - zenith angle of sun shots (with, against, ... the sun) Scenic Example ==> Sauschwaenzlebahn (Testbilder ZIP) A travel with a steam train and hiking back more .... --------------------- I think this could help you for now. The zenith angle of sun shots could be interesting to build and test a “sun filter”. With coordinates + GPS time/date it is possible to filter all pictures taken as dusk, dawn, … With compass data added you can filter all pictures with frontal sun, sun from the back, sun from the right, … In combination you can filter all frontal pictures of sundowns, … Prototype: https://www.gps-camera.eu/news/45-news/285-fotos-nach-sonnenstand-und-lichtstimmung-filtern-dank-geotagging.html Cheers Seb the sun direction filter is this https://bugs.kde.org/show_bug.cgi?id=303063 There are a lot of camera support this feature by now and it is very useful to some users like geologist,... Note that it helps a lot when trying to manually add gps coordinats to the photo. Indeed if you can see the angle of view on the map , you can see what was photographed, I frequently uses this to perfectly set my pictures on geosetter. You can check this feature request thread on geosetter that was used to implements the feature in it: http://www.geosetter.de/mantis/view.php?id=82 A few great feature of geosetter: -the direction is drawn as a transparent triangle that represent the camera field of view. the field of view is computed from the focal length and sensor size (geosetter has a list of camera sensor size relative to 24*36 format but you can also get it from exif on some camera model) -you can set the direction as being magnetic or true north what could be added: -the size of the triangle can be computed from the horizon distance ( http://de.wikipedia.org/wiki/Potenz_(Geometrie) ) -Magnetic north could be corrected to geographic north to correct the declination you can have a look there, they give the source code in C and the data. http://www.ngdc.noaa.gov/geomag/WMM/soft.shtml [^] an example of web site using it with google map: http://www.magnetic-declination.com/what-is-magnetic-declination.php Also note that more software start supporting this like lightroom (even if it is extremely basic in lightroom) Me too: please add support to add heading/destination data in the metadata editor. For me this missing possibility is one of the few reasons to still use windows (in this case it means: to use geosetter) instead of linux ... the geosetter examples which Eric names show quite good what is meant. Mee too - Eric described it very well! I got the Solmeta MAX-EOS but I use it only as a logger on my Olympus camera (Solmeta supports only Nikon & Canon) - the data are stored as NMEA log. Apart from digiKam not handling the GPSImgDirection tag yet, there is a problem that GPX standard does not define heading at all (older version did define course, but that's not the same as heading). So digiKam should allow to GPS Correlate also from other file types (various NMEA data, possibly others). *** Bug 457150 has been marked as a duplicate of this bug. *** |
