Title:
SURFACE LAYER DENSITY VALUE ESTIMATION METHOD OF GRAVITY DEVIATION DATA
Document Type and Number:
Japanese Patent JP2017138124
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To estimate a surface layer density distribution such as applicable with a landform correction value high in spatial resolution added with a surface layer landform, a layer thickness and a density, in a space gravity deviation method survey data analysis.SOLUTION: A surface layer density value estimation method of the gravity for performing grip of horizontal gravity gradient data acquires a horizontal gravity gradient value at each grid point, prepares horizontal gravity gradient grid data, overlaps an origin of addition factor grid data in each grid, acquires a numerical value multiplying the horizontal gravity gradient value by an addition factor, calculates a horizontal gravity gradient polymerization value, prepares the horizontal gravity gradient polymerization data, and estimates a surface layer density value from a linear correlation analysis with synthesis horizontal gravity gradient polymerization data resulting from a surface layer mass calculated from the horizontal gravity gradient polymerization data and a landform altitude data.SELECTED DRAWING: Figure 2
