Digital generalization of spatial data has been the goal of the research in many research centers around the world. This article presents the evolution of car****tographic generalization, drawing the reader's attention to the change of its nature from analog to digital. Despite the passage of time and developing technologies, scientists have unfortunately yet to develop a uniform automat****ic generalization algorithm. One of the factors that hinder this process is the high complexity and complication of the whole process. The article is an at****tempt to answer this problem and addresses the issue of digital cartographic generalization by creating a proposal of thresholds and stages of cartograph****ic generalization depending on the ratios of the numbers of points of general****ized objects. The publication attempts to examine the possibility of applying an objective criterion of drawing recognition by examining digital generalization algorithms and setting its thresholds. The practical aim of the publication is to present generalization thresholds on the example of Chrobak's algorithm. The proposal to make the selection of generalization thresholds dependent on the percentage share of points is a solution that is as simple to use as it is to implement. The method of defining intervals based on the three-sigma rule is a solution that guarantees that the obtained results will be characteristic of the probability density function of the normal distribution, which will define individual intervals most objectively(original abstract)
