El sistema defensivo de Villasviejas de Tamuja (Botija, Cáceres): una aplicación de software libre en el análisis de paisajes arqueológicos

Abstract

[ES]: El análisis de cuencas visuales es una de las aplicaciones de los SIG que más repercusión han tenido en Arqueología. El éxito de su uso está condicionado también por la elección del método de elaboración de los modelos digitales del terreno, bien sea a partir de modelos obtenidos por triangulación o por interpolación (splines, etc). Es ésta una consideración de partida que pretendemos incluir en esta comunicación. En este trabajo se ha empleado el software GRASS para tratar de comprender diversos aspectos sobre la función del sistema defensivo de un poblado amurallado de la II Edad del Hierro, especialmente módulos adicionales específicamente desarrollados para Arqueología. Nuestro trabajo se ha centrado esencialmente en las cuencas visuales y en el análisis de prominencia, aunque no hemos querido obviar otras posibilidades como el cálculo de caminos óptimos para comprender los accesos al castro. Con esta aplicación práctica puede ponerse de relieve la versatilidad de este paquete de software libre frente a otras soluciones que se emplean en el mercado.

[EN]: The analysis of cumulative viewshed is one of the GIS applications which has had a great impact in Archaeology. The success of its use depends on the election of the elaboration method of the DEM, obtaining models either by triangulation or interpolación (splines). This is one basic premise we try to include in this communication. In this paper, GRASS software has been used in order to understand diverse aspects about the function of the defensive system of a Late Iron Age hillfort, using also additional commands specifically developed for Archaeology. This work mainly studies the cumulative viewshed and the prominence analysis, including also other possibilities as the least cost path. With this practical application we want to point out the versatility of this free software package front to other solutions available.
