Vario-scale data structures supporting smooth zoom and progressive transfer of 2D and 3D data
International Journal of Geographical Information Science
This paper introduces the concept of the smooth topological Generalized Area Partitioning (tGAP) structure represented by a space-scale partition, which we term the space-scale cube. We take the view of 'map generalization as extrusion of data into an additional dimension'. For 2D objects the resulting vario-scale representation is a 3D structure, while for 3D objects the result is a 4D structure. This paper provides insights in: (1) creating valid data for the cube and proof that this isdoi:10.1080/13658816.2013.809724 fatcat:eky27iazrjhnlczwr5y7zlekba
