| Popis: | One of the basic elements when designing policy analysis, management and land use planning is a good land use mapping. For this purpose, there is the Corine Land Cover (CLC) at European level and SIOSE (Occupation Information System Soil Spain) nationwide. Processes updating of this cartography are often costly, and this is where the techniques of remote sensing of the Earth can be of great help. This work is to obtain, through a multi-temporal analysis between SPOT 5 images of 2009 and 2011, an effective method of detecting changes in a heterogeneous level of coverage as the Galician field. To achieve the identification of areas where there has been modification of land uses, new channels that collect differences (radiometric and structural) from SPOT images for both years are generated. Then, several classifications are made in these channels obtaining a layer changes. This layer changes supported with images PNOA (National Aviation Plan Orthophotography) is a reliable and useful information for a directed photointerpretation in SIOSE update, thereby reducing the execution time and maintaining the quality of the final database |
