Island map
The island map shows individual, mostly flat objects on the earth's surface without their surroundings. Their scope is determined by topographical conditions such as paths, natural boundaries such as bodies of water, or man-made boundaries such as administrative units .
An island-like display can also arise if the area in focus is completely reproduced, but the content is reduced to the extent that, for example, only main rivers and the main traffic routes are entered there.
The advantage of an island map compared to a frame map is that the representation of the location can be adapted and the effort to represent the object and the surrounding area in a defined frame is eliminated.
Disadvantages are the lack of the possibility of simply assembling several island maps (without digitization and fitting them using control points ) into a map (e.g. by gluing them together) or integrating them into an entire map series , as well as in the absence of clues when attempting the To locate the area in its surroundings.
