摘要

简历地理空间数据越来越多地用于沿海地区的地形建模，特别是浅水体（深度高达1米）。为了生成地形起伏，重要的是选择一种能够准确投影的建模方法。因此，本出版物的目的是分析沿海地区的地形建模方法。为了进行研究，介绍了五种最流行的地形建模方法：逆距离加权法（IDW）、修正谢泼德法（MSM）、自然邻域插值法（NNI）、克里格法和样条法。每种方法都以统一的方式描述：其操作的本质、数学表达式和应用示例。还讨论了每种地形建模方法的优缺点。应该指出的是，浅水体地形建模方法的选择并不明确，因为它取决于测深和摄影测量期间记录的数据类型。

Analysis of Terrain Modelling Methods in the Coastal Zone

Resume Geospatial data are increasingly used to model the terrain in the coastal zone, in particular in shallow waterbodies (with a depth of up to 1 m). In order to generate a terrain relief, it is important to choose a method for its modelling that will allow it to be accurately projected. Therefore, the aim of this publication is to analyze the terrain modelling methods in the coastal zone. For the purposes of the research, five most popular methods for terrain modelling were described: Inverse Distance Weighted (IDW), Modified Shepard’s Method (MSM), Natural Neighbor Interpolation (NNI), kriging and spline. Each of the methods has been described in a uniform way in terms of: the essence of its operation, mathematical expression and application examples. The advantages and disadvantages of each of the methods for terrain modelling are also discussed. It should be stated that the choice of the method for the terrain modelling of a shallow waterbody is not unambiguous, as it depends on the type of data recorded during bathymetric and photogrammetric measurements.

期刊介绍： The journal covers the areas in which the faculties and workplaces of the university develop their activities. Communications are seen from a broader point of view: as a means of disseminating information, as an important tool of an information society and, most of all, as a means for providing information. The papers do not deal strictly with communications, but they approach the mentioned area in a more complex way and from different viewpoints. The journal is published mainly for university and academy staff, workers of research institutes and also for the wider community of readers.
