Height grid plus geoid

The product consists of the two parts

1 – Height grid plus geoid
The height grid plus geoid enables the transformation of ellipsoidal heights in the ERTS89/GRS80 system at heights of the MGI with reference to Adria 1875 (use heights H.ü.A.) in one step.
Suitable for transforming heights, e.g. from laser scanning data present in the ETRS89/GRS80 system, at application heights of the MGI (at level of level of level).

2 – Correction values of the altitude fixed points to the altitude grid
The correction values KLFP to the height grid are used to correct the usage heights contained in the point maps of the position points in order to achieve conformity with the usage heights derived by means of GNSS measurements, geoidundulations and height grid.
Suitable for adjusting usage heights (e.g. for laser scanning) generated with the height grid plus geoid from ellipsoidal heights, with the usage heights of the positioning points.

本数据集包含两部分内容：
1. 高程格网与大地水准面（Height grid plus geoid）
该组件可实现一步式坐标转换，将ERTS89/GRS80椭球坐标系下的椭球高程，转换为以Adria 1875为基准的MGI系统下的使用高程（H.ü.A.）。其适用于将ETRS89/GRS80坐标系下的激光扫描数据等高程数据，转换为MGI系统应用场景下的使用高程。
2. 高程定点至高程格网的改正值（Correction values of the altitude fixed points to the altitude grid）
高程格网对应的KLFP改正值，可用于校正定位点点位图中包含的使用高程，使其与通过全球导航卫星系统（GNSS）测量、大地水准面起伏（geoid undulations）及高程格网计算得到的使用高程保持一致。该改正值适用于对由高程格网与大地水准面从椭球高程转换得到的使用高程（例如激光扫描相关高程）进行平差，使其与定位点的使用高程相匹配。
