| 1. | The dem format encodes elevation data to create highly detailed terrains
Dem格式编码高程数据来创建高清晰地形。 |
| 2. | The elevation data , which constructs the digital elevation model ? ? dem , is very important
高程数据是构建数字高程模型( dem )的数据基础。 |
| 3. | Mapping application developers : combine raster , vector and elevation data to create dynamic moving maps using kinemap digital map software
数字地图制作工具，将光栅、矢量和海拔数据生成动态地图。 |
| 4. | Previously the elevation data of many mountains in china are inconsistent and inaccurate due to technological and equipment limits
由于技术和设备的限制，中国现存的许多山脉的测量数据存在着不统一，不准确的现象。 |
| 5. | Previously the elevation data of many mountains in china are inconsistent and inaccurate due to technological and equipment limits
以前，由于技术和设备的限制，中国的许多山峰的海拔数据存在着不统一，不准确的现象。 |
| 6. | Because the elevation data we have acquired through gps is too variable to satisfy the mapping accuracy requirement the elevation value is solved by the water lever observation in the hydrology station and datum horizon correction of sounding observation
由于gps的rtk模式测量所获取的高程精度不能满足测图精度要求，因此其高程值是通过测量水深值、结合其统一到基准面的改正数、根据相关水文部门各水位站提供的水位观测资料综合计算获得。 |
