This paper presents an algorithm to improve the spatial resolution, from 90 m to 30 m, of the thermal mapping of small bodies of water or near coasts obtained from the ASTER satellite sensor. The entire procedure is based only on ASTER images. The frst part of the work deals with the physical and mathematical basis on which the algorithm was constructed, the schema of the main steps and the methods of validation of the algorithm. In the second part two applications of the algorithm are shown, the frst on the area of the delta of the Po River (Italy), the second on the lagoon of Venice (Italy).

Abstract
This paper presents an algorithm to improve the spatial resolution, from 90 m to 30 m, of the thermal mapping of small bodies of water or near coasts obtained from the ASTER satellite sensor. The entire procedure is based only on ASTER images. The frst part of the work deals with the physical and mathematical basis on which the algorithm was constructed, the schema of the main steps and the methods of validation of the algorithm. In the second part two applications of the algorithm are shown, the frst on the area of the delta of the Po River (Italy), the second on the lagoon of Venice (Italy).
