摘要: In mineral exploration, resource assessment, or natural hazard many layers of geoscience maps such as lithology, structure, geophysics, geochemistry, hydrology, slope stability, deposits, and preprocessed remotely sensed data can be used evidence to delineate potential areas for further investigation. Today's PC-based base management systems, statistical packages, spreadsheets, image processing geographical information systems provide almost unlimited capabilities manipulating data. Generally manipulations make a strategic separation spatial nonspatial attributes, which are conveniently linked in relational bases. The first step integration procedures usually consists studying the individual charateristics map features interrelationships, then representing them numerical form (statistics) finding high (or impact).
