THE USE OF BREAKLINES OF HYDROGRAPHIC OBJECTS IN THREE-DIMENSIONAL MODELING OF CITIES

Abstract. Three-dimensional polygonal models are used for various tasks. They are created based on aerial photography or aerial laser scanning. In this paper, a study is conducted on what tasks require the correct geometry of the model on water bodies. The main modeling problem related to the scanner and photogrammetric processing feature is described. The general scheme of creating mesh models is given. The authors propose a method for using breaklines and generating synthetic points on hydrographic objects. The authors describe the idea of the method, and also mention their technical implementation. The paper presents information about the source data and the result on one data example. The authors leave a lot of topics for discussion, as the method requires development.
