- Abstract
- In this paper, we put forward the development of a solution allowing modeling and exploitation of real time synthesized images of the globe. This is used for presenting the weather forecast bulletin of Tunisian television Channel 7. This presentation requires a smooth panning to any part of the world, while having the necessary level of detail. To store and handle geographical data, most of the used methods implement a tree structure of data where various threads come out of each node (four in the case of quadtree). Recursively, one goes down the tree until a satisfactory level of detail is reached. Our contribution consists in the adaptation of this algorithm to a sphere and the exploitation of various filtering, storage and optimization techniques in connection with the available material
