Semi-automatic vectorization of linear networks on rasterized cartographic maps
Abstract
A system for semi-automatic vectorization of linear networks (roads, rivers, etc.) on rasterized cartographic maps is presented. In this system, human intervention is limited to a graphic, interactive selection of the color attributes of the information to be obtained. Using this data, the system performs a preliminary extraction of the linear network, which is subsequently completed, refined and vectorized by means of an automatic procedure. Results on maps of different sources and scales are included. ----- Se presenta un sistema semi-automatico de vectorizacion de redes de objetos lineales (carreteras, rios, etc.) en mapas cartograficos digitalizados. En este sistema, la intervencion humana queda reducida a la seleccion grafica interactiva de los atributos de color de la informacion a obtener. Con estos datos, el sistema realiza una extraccion preliminar de la red lineal, que se completa, refina y vectoriza mediante un procedimiento automatico. Se presentan resultados de la aplicacion del sistema sobre imagenes digitalizadas de mapas de distinta procedencia y escala.
