Abstract

The Croatian height transformation model (HTMV) enables the transformation of absolute heights of discrete points with known horizontal positions from the Trieste 1875 reference system used throughout the former Republic of Yugoslavia and in Croatia known as HVRS1875 to the new height reference system of the Republic of Croatia (HVRS71) and vice versa. The HTMV is realised as a grid transformation model based on separate modelling of datum and distortion components comprised in height differences. The quality of the transformation model is assessed by comparing the difference in height values at benchmarks that were not used in the model derivation against height differences at the benchmark locations interpolated from the model. The results indicate a high external and internal accuracy of the transformation process, which points to the adequacy of the HTMV utilisation for engineering purposes.

克罗地亚高度转换模型的精度评估

克罗地亚高度转换模型(HTMV)能够将已知水平位置的离散点的绝对高度从前南斯拉夫共和国和克罗地亚使用的的里雅斯特1875参考系统(称为HVRS1875)转换为克罗地亚共和国的新高度参考系统(HVRS71)，反之亦然。HTMV是作为一个网格转换模型实现的，该模型基于由高差组成的基准和失真分量的单独建模。转换模型的质量是通过比较模型派生中未使用的基准高度值的差异与从模型中插入的基准位置的高度差异来评估的。结果表明转换过程具有很高的外部和内部准确性，这表明HTMV用于工程目的的充分性。

期刊介绍： Survey Review is an international journal that has been published since 1931, until recently under the auspices of the Commonwealth Association of Surveying and Land Economy (CASLE). The journal is now published for Survey Review Ltd and brings together research, theory and practice of positioning and measurement, engineering surveying, cadastre and land management, and spatial information management. All papers are peer reviewed and are drawn from an international community, including government, private industry and academia. Survey Review is invaluable to practitioners, academics, researchers and students who are anxious to maintain their currency of knowledge in a rapidly developing field.
