Our illustrated maps are designed from the beginning based on the regular topographic maps of the cities they represent. Therefor it is a necessary precondition for using our illustrations as navigational support, that the user must be able to read and use a regular topographic map at first place.
Our illustrated maps, are not a simple artistic-free representation of the city. They designed from the beginning to be in topologic accordance with the official topographic map of the city.
All though an accuracy of 98% is achieved in comparison to the regular topographic map, our illustrations depict that topographic in a prospective view following the rules of prospective in painting, in order to achieve the illusion of a 3 dimensional surface for our illustrations. In that way, various deformations are applied and thus some parts of the map may be elongated or suppressed in size.
As a consequence of these deformations, while distances remain proportionally correct between them, specific parts of the area depicted, may vary in size or shape in comparison to the real terrain they represents. This feature places our illustrated maps to the "variable scale" type of prospective designs, such as the 3D "birds eye view" are.
Therefore, our illustrations can not be used for calculations that requires or produce "absolute measurements" for distances, shapes or sizes.
Our illustrated maps are designed to be used as a recreational mean that helps general navigational purposes for a loose walk-around and we sincerely do not recommend to be used under any condition of navigational stress, for professional or emergency or any other liable way for the user. When absolute accuracy in calculation is needed, use a regular topographic map which is designed to provide all metrical features in the proper accuracy level for such use.
