合并DSM和DEM为DS&EM数据的一体化存储方案研究

Research on Integrated Storage Scheme of DS&EM Data by Merging DSM and DEM

目前同一区域的DEM、DSM成果,是以同一种数据格式按两个不同的数据文件进行存储,当某一区域为裸露地表时,其数据完全一致,存在数据冗余,同时高度关联的两套数据分开存放,不利于数据的生产和维护,且在地表裸露区域极易产生数值矛盾。本文提出的合并DSM和DEM为DS&EM数据的一体化存储方案,能有效地解决上述问题,供大家参考。

At present, DEM and DSM results in the same region are stored in the same data format according to two different data files. When an area is bare ground, its data is completely consistent and there is data redundancy. At the same time, the two sets of highly correlated data are stored separately, which is not conducive to data production and maintenance, and numerical contradictions are easy to occur in the bare round areas. The integrated storage scheme combining DSM and DEM as DS&EM data proposed in this paper can effectively solve the above problems for reference.
