Dos notas de geografía histórica apoyadas en fotografía aérea

Abstract

Two notes of historical geography supported by aerial photography.- In this paper, we present two small searches of historical geography which are supported by the combined use of archive sources, field work and sequencial images of aerial photography. One of this is located on the upper valley of Besaya river, and it studies settlement evolution related with the changes of communications network from xviiith century until now. The other search, located on the Cabezón de la Sal valley, set out a regressive hypothesis about the evolution of a medieval hydraulic system.
