Hi,

I have been trying to figure out the following issue for the last couple of days, to no avail. When taking a stand-alone photos, all geolocations are shifted by an approximately constant shift of about 100 m. It looks exactly like the typical shift when one forgets to apply the datum transformation needed for the specific projection I am using (Israel Transverse Mercator, for the matter). Therefore I suspect that there is something going on with the datum transformation applied to the photo layer. The same problem happens when using the Photo Point option - I tap the map, and immediately the photo location jumps some 100 m aside. Apart from that everything works fine. Maps are shown correctly, GPS positions recorded properly. As a workaround I am currently using photos associated with point features - works just fine.

I observed that, when starting a new map in one of the default projections, e.g. World Transverse Mercator, the photo layer is geolocated properly. Furthermore, when loading the created map into a new project in my projected coordinate system, the photo layer is reprojected properly!

Currently I am using a non-default definition of the required datum in the Transfroms.dbf and DefaultTransforms.dbf. Disabling these files and thus forcing the use of the default datum definitions did not cure the problem - hence I ruled it out as a possible reason.

I would appreciate if someone could shed some light on this.

BR, Reuven

A week or so days before the ceremony or an event, they are photographic services that supply the photographer with a list of moments that are important. We need to pick and choose from these photo ops, keeping them a side the best one.So,that the photographer would give us the style that we like to have.
