There are currently two separate approaches to obtaining digital elevation models of the terrain surface by remote sensing, image based methods using aerial or satellite images and scanner techniques by terrain laser scanners. Each method provides elevations with high accuracy, but both require significant input from an operator during processing. It is proposed to take advantage of the synegies of these two forms of data by combining the processing into a single solution for elevation determination by data fusion. This approach will improve the quality and efficiency of elevation determination.

目前有两种不同的方法来获得数字高程模型的地形表面的遥感，图像为基础的方法使用航空或卫星图像和扫描仪技术的地形激光扫描仪。 每种方法都提供了高精度的高程，但在处理过程中都需要操作员的大量输入。建议利用这两种形式的数据的synegies，通过将处理组合成一个单一的解决方案，通过数据融合的高程确定。 该方法将提高高程确定的质量和效率。
