An research of building digital elevation model and visualization based on ImageJ

Digital elevation model (DEM) that is a good method of digital terrain,lmageJ is a pure java language with the scientif- ic image processing software.This article had in the algorithm foundation in the analysis,proposed an research of building DEM and Vi- sualization base on ImageJ.The primary merit of this algorithm is that its data structure is not only simple but also facile.By testing and analyzing data,it indicates that the speed of this algorithm is higher than the other algorithm.
