Abstract:
A method for constructing a solid three-dimensional polygonal model of a three-dimensional irregular volume within a GIS platform comprising:(a) introducing desired data including control points and attributes relating to said three-dimensional irregular volume into said GIS platform; (b) estimating at least one two-dimensional polygon representing a lateral boundary of said three-dimensional irregular volume based upon values of variable of interest at said control points; (c) estimating irregular surfaces representing top and bottom of said three-dimensional irregular volume by interpolating grids of depth values from said control points for said top and bottom surfaces of said three-dimensional irregular volume; (d) clipping said estimated irregular surfaces with said estimated at least one two-dimensional polygon; (e) constructing multipatches of a network of triangular panels representing top surface, bottom surface, and sides of said three-dimensional irregular volume to produce said solid three-dimensional irregular volume model within said GIS platform; and (f) joining said attributes to said solid three-dimensional irregular volume model within said GIS platform.
