 Selecting the Bounding Box for the coordinates: 
 (We ran into some issues here, as the order in which the coordinates have to be presented changed between Versions and the reference often does not specify which version it refers to...)
 The bounding box is constructed through presenting a minimum x-value, a minimum y-value, a max x-value and finally a max y-value.

 In order to set the size of the image presented we specified the with and the height of the image, note that a new "block" of the request starts with the addition of &styles, which is followed by all the attributes concerning the style of the map produced. Depending on the size chose the detail of the map varies greatly, for example a map with the size 780x780px is far more primititve than one with a size above 1000 px, although the api only allows to request images up to a certain size (4000px) until it sends an error message that tells you thatthe size you requested is too big.

 We set the format that is supposed to be requested to png.
 
-_&FORMAT=image/png_ -> set image format

 We then set the background to be transparent.

 We decided to use the more detailed bigger version of the image, as it is much more clear, although it could be considered to decrease the size if you want to save on ressources, as the larger image takes more time to download obviously.

 # Integration of the WMS Image into Google Earth:
-https://docs.geotools.org/latest/userguide/extension/wms/wms.html
+
+In order to integrate the WMS Image into Google Earth we wrote a method that requests the WMS Image from the Server, saves it locally and another method that then integrates the image into the KML structure as a Ground-Overlay.
