Geotagged images with minus longitiudes incorrectly shown

Reported by: kevjs1982 Owned by: cbro@…
Priority: major Milestone:
Component: merkaartor Version:
Keywords: Cc: merkaartor@…


When importing images Geotagged using GeoSetter? (they display okay in Google Earth) which have negative longitude value they are displayed at longitude value without the minus sign.

The attached image should be displayed at lat=52.94490900; lon=-1.08963100; but is actually displayed at lat=52.94490900; lon=1.08963100;

I don't have the problem on Windows.

If not windows, please state OS/Qt version/exiv2 version...

Someone else noticed this?

I fixed an issue with the sign of longitude and latitude a few months ago. My images from gpscorrelate were appearing the wrong side of the Greenwich Meridian.

To diagnose, it would be useful to have a dump of the data from the GPS* tags in the exif. E.g. from one of my images:

$ exiv2 -pv 20090909-121938.jpg | grep '^0x.... GPSInfo'
0x0000 GPSInfo      GPSVersionID                Byte        4  2 0 0 0 
0x0001 GPSInfo      GPSLatitudeRef              Ascii       2  N
0x0002 GPSInfo      GPSLatitude                 Rational    3  57/1 28/1 4203/100
0x0003 GPSInfo      GPSLongitudeRef             Ascii       2  W
0x0004 GPSInfo      GPSLongitude                Rational    3  4/1 5/1 3561/100
0x0005 GPSInfo      GPSAltitudeRef              Byte        1  0 
0x0006 GPSInfo      GPSAltitude                 Rational    1  764675/5000
0x0007 GPSInfo      GPSTimeStamp                SRational   3  12/1 19/1 38/1
0x0012 GPSInfo      GPSMapDatum                 Ascii       7  WGS-84
0x001d GPSInfo      GPSDateStamp                Ascii      11  2009:09:09

Obviously, it's the GPSLongitude and GPSLongitudeRef that are particularly interesting to this issue.

Replying to tms13:
