Method and device for pictorial representation of space-related data
DC CAFCFirst Claim
1. A method of providing a pictorial representation of space-related data of a selectable object, the representation corresponding to the a view of the object by an observer with a selectable location and a selectable direction of view comprising:
- (a) providing a plurality of spatially distributed data sources for storing space-related data;
(b) determining a field of view including the an area of the object to be represented through the a selection of the a distance of the observer to the object and the an angle of view of the observer to the object;
(c) requesting data for the field of view from at least one of the plurality of spatially distributed data sources;
(d) centrally storing the data for the field of view;
(e) representing the data for the field of view in a pictorial representation having one or more sections;
(f) using a computer, dividing each of the one or more sections having image resolutions below a desired image resolution into a plurality of smaller sections, requesting higher resolution space related space-related data for each of the smaller sections from at least one of the plurality of spatially distributed data sources, centrally storing the higher resolution space related space-related data, and representing the data for the field of view in a the pictorial representation; and
(g) repeating step (f), dividing the sections into smaller sections, until every section has the desired image resolution or no higher image resolution data is available.

Abstract
A method and device for the pictorial representation of space-related data, for example, geographical data of the earth. Such methods are used for visualising visualizing topographical or meteorological data in the form of weather maps or weather forecast films. Further fields of application are found in tourism, in traffic control, in navigation aids and also in studio technology. The space-related data, for example topography, actual cloud distribution, configurations of roads, rivers or frontiers, satellite images, actual temperatures, historical views, CAD-models, actual camera shots, are called up, stored or generated in a spatially distributed fashion. For a screen representation of a view of the object according to a field of view of a virtual observer, the required data are called up and shown only in the resolution required for each individual section of the image. The sub-division of the image into sections with different spatial resolutions is preferably effected according to the method of a binary or quadrant tree.
