　　建立区域大地水准数字模型，进而方便地内插出模型区域中任意点的高程异常值，可以解决GPS定位技术无法直接获取正常高而求得高程问题，对科学研究和生产应用具有很大的参考价值。将DEM建模技术与区域大地水准面研究相结合，建立高精度的区域高程异常数字模型，从而内插出该区域内任何一点或一小片区域的高程异常值，并通过网络将空间信息动态地向社会发布，可以方便各类测绘用户获取所需的地理空间信息，进一步提高测绘对科学研究和社会生产的服务水平。

Through establishing regional geoid digital model and interpolating height anomaly value of any point in model regions conveniently ,it may solve the problem that GPS localization technology can′t directly obtain normal height to solve elevation , and it has the reference for the scientific research and production application.Combined the DEM modeling technology with the regional geoid study ,the high accuracy regional height anomaly digital model is established , in order to interpolate the height anomaly value of any point or plot in this region, and the spatial information is issued to the public dynamically through the network, and it can be convenient for any kind of surveying and mapping users to acquire the geographic spatial information which they need , further to enhance the service level of surveying and mapping for science research and social production .
