Abstract:
1. A method for determining relative elevation values of an allotment by using a computer, the allotment comprising a surface having a length L, a width W, and a plurality of nodes i, wherein the total number of said nodes is n; i is a first integral variable and is in the range of [1,n]; said nodes have a row spacing dy and a column spacing dx; and each of said nodes has a relative elevation value relative to said surface; said relative elevation values have a mean z and a standard deviation S d ; the method comprising: a) generating an initial data set of said relative elevation values comprising z b) by means of the computer, adjusting the initial data set to establish a first adjusted data set of said relative elevation values having spatial dependence and comprising z c) by means of the computer, making statistical parameter corrections to the first adjusted data set to obtain a final data set of said relative elevation values comprising z d) saving the final data set of said relative elevation values; and e) determining elevation distribution of the allotment based on said final data set of said relative elevation values saved in step d) and fixing the elevation distribution of the allotment on a physical medium.
