AUTOMATIC VECTORIZATION OF INPUT DATA FOR MODELS OF TRANSPORTATION SYSTEMS

Abstract

Digital (vector) data is essential for modeling of transportation systems and solving of optimization problems. This input data is often represented by raster maps and drawings in practice and it is necessary to vectorize them. Manual and semi-automatic vectorization is expensive and time consuming and that’s why the room for automation of this process is opened. Today there are many tools for pattern recognition in raster images which are part of the digital image processing tasks. Although vectorization of maps with transportation infrastructure is complex problem, in case of drawing maps it is possible to define the main features for the process of automatic vectorizaion. In this paper process of automatic vectorization of maps with transportation infrastructure is shown.
