The Summit-level Map of the Himalaya-Tien Shan Area and the Isopleth Maps of N Values in the Kyoto Basin based on Modeling of Grid Data

Abstract

A method for modeling of grid data converted from irregularly spaced data provides a bird's-eye view or three dimensional structure that allows the geological interpreter to see landforms or geologic structures. This study examined two interpolation methods— (1) a method for moving random data in the center of the mesh and (2) a method of interpolation based on the principle of total minimum curvature. In addition, the first method was used to construct the summitlevel map of the area including the Himalaya range, the Tibet plateau and the Tien Shan range. The map revealed that while the southern slope of the Himalaya mountains is very steep, the topographic features of the Tibet zone are low-relief plateau and that the peneplain is left on the middle slope of the Tien Shan mountains. Furthermore, the isopleth maps of N values inthe Kyoto Basin were drawn by using the moving average method of interpolation.
