3DGRT_AXIS_EPSG25830_v2.zip

Points precise derived from a sequence of Geodetic GNSS device stored on a Shapefile. Reference system is EPSG 25830 and includes Easting (X coordinate), Northing (Y coordinate), ellipsoidal height, direction of capture and precision of the observation.本数据集的精确点位源自存储于Shapefile中的一系列大地测量GNSS设备的观测序列。其采用的坐标参考系统为EPSG 25830，包含东向（X坐标）、北向（Y坐标）、椭球高程、采集方向以及观测精度等信息。
