Possibilities of developing maps of sight-aesthetic attractiveness of underwater landscapes of lakes using the point-valuation method and spatial interpolation methods

Motives: The research investigates the feasibility of using interpolation algorithms for assessment using the point-valuation method in different types of lakes. It shows the possibilities of using the proposed methodology for underwater landscapes under various environmental and geographical conditions. Aim: The aim of the study is to test the point-valuation method for assessing the sight-aesthetic value of lakes in terms of potential for tourist exploration. The results are presented in the form of maps, resulting from spatial interpolation methods based on a random measurement network. Results: Maps showing the distribution of the phenomenon under study can serve as a tool for protection and planning of development and tourist use of lakes. Dedicated spatial interpolation methods for this type of assessment map were identified. The methodology is universal and can be applied, with appropriate modifications, in various types of water bodies (lakes). Conclusion: Successful implementation of point-valuation methods and interpolation algorithms for assessing the sight-aesthetic attractiveness of underwater landscapes of lakes has been achieved. These are pioneering studies in the field of underwater landscape perception and cartographic presentation methodology. This contributes to the development of principles for protection, tourist use (qualified tourism – diving), and channelling tourist traffic in places attractive to users.
