The Bonne pseudo-conic projection for the territory of the Republic of Moldova

Abstract

The paper presents a study on the equivalent pseudo-conic Bonne map projection for the representation of the territory of the Republic of Moldova and the associated cartographic grid, providing a rigorous and efficient mathematical method for calculating point positions within this projection. The primary aim of the study is to ensure increased accuracy of cartographic data and to minimize specific deformation errors, such as linear and angular distortions, which may occur during the process of depicting the Earth's surface on maps. The article delves into the methodological details of the calculations involved in applying the Bonne projection, focusing on the analysis of geometric errors and identifying the most effective techniques for determining these errors. Additionally, it offers a comprehensive approach to the process of automating calculations by developing specialized algorithms implemented using modern programming languages. These algorithms are capable of generating precise results, which can subsequently be exported in formats compatible with CAD or GIS systems, facilitating their integration into professional cartographic workflows. Another aspect of the paper is the graphical analysis of the territory of the Republic of Moldova in the Bonne projection. The graphical representation was carried out using AutoCAD software, highlighting both the advantages and limitations of this projection, with a precise indication of the deformations encountered. The paper emphasizes the importance of algorithmizing the calculation process as part of modernizing the geospatial infrastructure, underlining the relevance of using an equivalent projection to achieve a faithful representation of the Earth's surface.
