[Digikam-devel] GPS wrong coordinate conversion?

[Arnd Baecker]

Hi,

maybe I am wrong, but I think that the conversion in the example
given at
http://docs.kde.org/development/en/extragear-graphics/digikam/using-kapp-camera.html#using-kapp-gps
is not correct:

"""The positional data (e.g. 13.44088333) must be converted into H.MS
format (13.235990) and split into its constituents as shown in the given
example."""

which leads to the entry
  add Exif.GPSInfo.GPSLatitude Rational "13/1 23/1 5990/100"

Doesn't 13.44088333 convert to: 13 26 27.18:
  int(13.44088333)       = 13
  int(0.44088333*60)     = 26
  (0.44088333*60-26) *60 = 27.18

The converter at http://www2.comp.polyu.edu.hk/~04329143d/Location.html
also gives these numbers.
If this is correct, it should read
  add Exif.GPSInfo.GPSLatitude Rational "13/1 26/1 2718/100"

The other way round, "13/1 23/1 5990/100"
would correspond to: 13.399972.

Best, Arnd
