Every year, floods cause great damage in the Republic of Serbia. The lack of solutions for flood riskmanagement and prevention during their escalation causes great financial deficit. One of thesolutions for achieving stability in this sphere is creating a map of flood threats and risk accordingto the European Flood Directive. The task of the IPA2014 action is the creation of those maps usingthe latest technology in laser scanning of terrain, or LiDAR sensors. Scanning the terrain from airusing the aforementioned technology gathers data which by later processing results in very precisedigital models of terrain which are used as the foundation for mapmaking.
Globally, maps are our primary source of comprehensive information about the shape, size and arrangement of Earth features. Maps are the only way we can get a unique and comprehensive view of the world. Unfortunately, globally, all maps are somehow deformed, affecting our perception and understanding of the various geometrical properties of the world. Cartographic projection is a way of mapping points from an ellipsoid to a plane and as such is the basis for making a mathematical map basis. The two projections most used in our geospatial are the Gauss-Krüger projection and the UTM (Universal Transverse Mercator) projection. The paper deals with Helmert's transformation of these two projections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
