Improve support for GPS data with a custom GeoLocation class #15

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
GpsDirectory should have a new method that returns the latitude/longitude as a 
new object type that allows conversion between different representations 
(decimal, DMS, etc.)

At the very least, it would be handy to have a way to convert the lat/lon 
Rational[] into a float, even if it was a hidden/undocumented method until 
there is time to build this new GeoLocation class.

Code for this has been committed and will be available in the next release.

To see it in action, check out the new sample application:

http://code.google.com/p/metadata-extractor/source/browse/Samples/com/drew/metad
ata/GeoTagMapBuilder.java

In short, you can write code like this:

{{{
GeoLocation geoLocation = gpsDirectory.getGeoLocation();
if (geoLocation == null || geoLocation.isZero())
{
    // geoLocation.Latitude / geoLocation.Longitude
} 
}}}
