Geração de características vetoriais em terrenos usando GIS

Abstract

This work presents a solution for the generation of a polygonal mesh focused on the construction of the junctions between rivers/roads, which is used in the process of rendering the feature over the terrain. The approach use as input a vector file of lines representing the river/road structure and after that execute a series of pre-processing steps in order to prepare the vector file data for the mesh construction stage. The developed solution allows the construction of junctions between any number of connections. The purpose of this approach is to create and export the vector mesh as well as the navigation graph in a common and easy-to-access format for applications that need to use them, without a need for mesh reconstruction.
