A digital Earth system based upon a hexagonal subdivision of a polyhedron representation of the Earth utilizes a computer-implemented method for assigning identifiers. The method comprises defining a tessellation of hexagonal cells, the tessellation having a first axis and a second axis, the first axis being perpendicular to a first side of the hexagonal cells, the second axis being 120 degrees from the first axis and being perpendicular to a second side of the hexagonal cells; selecting an origin cell for the tessellation and assigning a unique identifier comprising a first value and a second value thereto; and assigning a unique identifier to each cell other than the origin cell, the unique identifier for each of these cells comprising a first vector value and a second value, the first vector value and the second vector value being indicative of the location of the cell to the origin cell along the first and second axis respectively.

The present invention relates to a method and system for processing a volumetric dataset for providing close-up visualization of a subset therefrom. A volumetric dataset is processed based on a dual access gradient quantization data structure. The data structure is generated in a fast pre-processing stage and provides substantially immediate access to a quantized gradient using either an index or an arbitrary normalized vector. The method provides a clear, enlarged high-resolution image of a user selected region of interest at interactive rates and allows the user to freely move and visualize the region of interest within the volumetric dataset and with any orientation.
