In the beginning, there was code in digikam that displayed and grouped 
thumbnails of images on Marble, while in kipi-plugins there was a 
KHTML-based viewer for Google Maps, which only showed a marker at the 
position of the photo. Since we wanted both Marble and Google Maps in 
both places, we went the natural way of turning that code into a library 
so that it can be used in both places without duplicating code. 
Originally, we also wanted to show a web-based OpenStreetMap directly 
via KHTML to allow for more interaction with OpenStreetMap's layering 
options, but that option was abandoned because of incompatibilities 
between KHTML and OpenStreetMap's OpenLayer Javascript code at that time.

 From the way I understood the terms of service, yes, this usage is ok. 
We also had a Google Summer of Code student work on the library, and the 
project was not rejected by Google. Of course I would rather see a 
collection of open data satellite imagery to be used instead, but I 
could not find any yet.
