INTEGRATION OF MULTIPLE GEO-SPATIAL DATASETS
Eliyahu Safra, Yerach Doytsher · 2006
When multiple geo-spatial datasets are integrated, the process should be done in several stages. In each stage two datasets are fused to one. Since different sequences may lead to different results, it is important to select a sequence that would lead to the required results. Two approaches, namely the sequential and hierarchical, for selecting the sequence are presented, and their results are compared. In the sequential approach, initially two datasets are integrated, then, in each stage the result of the previous stage is integrated with a fresh dataset. In the hierarchical approach, in each stage, every pair of datasets is integrated to one, until there is only one dataset. The results of extensive experimentations are presented. The tests show that for large overlap the second approach have better results in a cost of lower versatility.
