摘要：Basing on his long-term research on the algorithms used for the digital landscape model generalization,the author is able to determine the elements which are crucial for the automation of the very process. These elements are,above all,data arrangement and clarity of the processes. The author has carried out the analysis of the application and the influence which the objects’ fixed points have in the model generalization – he has investigated how particular simplification algorithms behave. In the paper he presents the results of his analysis. According to the definition,fixed points should have a significant influence on the simplification process quality. This is because they not only remain invariable in the transformations,but also let us apply the clear data classification in the process. In order to demonstrate the influence of the fixed points on the simplification process,the author chose a fragment of the Welsh coast and carried out the simplification process,using particular algorithms (Douglas-Peucker,Visvalingam,Wang,Chrobak). The test gives the reader an opportunity to compare the algorithms using the recognition standard.
