Abstract

The paper presents the results of works in an anamorphic map portal. The Gastner-Newman algorithm was used for calculations. A geoportal user can control parameters such as the Gaussian blur parameter and the population grid size, as well as the degree of generalization of areas’ boundaries and the degree of population data aggregation. A number of libraries and JavaScript solutions were applied in the geoportal, with some of them being partially modified. As a result, an interactive map portal was created that meets its educational and cognitive purposes.
