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.
