DEM产品质量检查标准研究与实现

The Research and Implementation on the Spatial Data Quality Check and Assessment Standard about DEM Data

随着测绘技术的发展进步,测绘产品质量特点也发生了质的变化。本文从生产实际出发,深入分析了测绘成果质量评定标准,探讨了DEM产品质量检查与评价,基于C#.Net平台设计并实现了"DEM质量检查与评价系统"。实践证明,该系统能够大幅度提高DEM质量检查效率,实现对DEM质量的良好控制,对测绘生产单位具有重要意义。

With the mapping technology development and progress, the mapping product characteristics have undergone a qualitative change. This paper deeply analyses the quality assessment criteria of mapping results and evaluation of the DEM products,based on C #. Net platform designs and implements the DEM quality inspection and evaluation system. Experiment has proved that the system can greatly improve the inspection efficiency of DEM quality, and achieve good control on the DEM quality of mapping units.
