A METHOD OF VISUALIZING 3D TERRAIN

摘要

A METHOD OF VISUALIZING 3D TERRAIN IN A WEB BASED ENVIRONMENT BASED ON INPUT FROM GEOGRAPHICAL INDICATION MEANS, THE METHOD INCLUDES THE STEPS OF IDENTIFYING AREA TO BE VISUALIZED, PREPARING CONTOUR AND IMAGING DATA FROM GEOGRAPHICAL INDICATION MEANS, PROCESSING THE PREPARED DATA TO PRODUCE DATA LAYERS, COMPRESSING THE DATA LAYERS AND ORGANIZING THE COMPRESSED DATA LAYERS TO BE PRESENTED IN A WEB ENVIRONMENT; WHEREIN A DIGITAL ELEVATION MODEL (DEM) IS CREATED FROM CONTOUR LINE LAYER AND CONTOUR LEVEL LAYER, SUCH THAT A R2V SOFTWARE IS BEING USED TO ADD HEIGHT VALUE TO THE CONTOUR LINE, WHERE THE HEIGHT VALUES FOR THE CONTOUR ARE BASED ON THE CONTOUR LEVEL LAYERS, AND THE HEIGHT VALUES ARE ADDED INCREMENTALLY TO WHOLE CONTOUR LINE.
