With displaying them on world map in statistics or in Google Earth it will be awesome!

I also totally subscribe to Jim's suggestion: displaying items on world map would be absolutely awesome, something I only dream about...

The other dream is to automatically display items on country maps by just entering the GPS coordinates in the edit window. I have seen such option in a small flash application: you only need the map and the coordinates of all four corners, then a dot is added according to the exact GPS coordinates... Awesome... (if the development team eventually decides to implement such feature, I could offer all country maps with the respective GPS coordinates for the corners).

Serge, could you please add also Geoogle Earth as predifined link?

Yes, it will be good, but it seems that there is no possibility to start Geoogle Earth without generation of the KLM/KMZ file; therefore we need to enhance GPS field type to support such operations (right now we have possibility to run shell command, for example open parametrized link). Furthermore, inside of the KLM file Decimal Degrees (WGS84) coordinate are used, but in GPS field you can type everything. So to run correctly Geoogle Earth, we need some mechanism to detect format/type of coordinate and convert it into WGS84 standard or into other standard according to external application demands.

It looks like, we need more work around this feature to make real solution for work with coordinates inside CollectionStudio or outside.
