Abstract: The multi-source data integration technique is a new technique developed on the basis of digital mapping. The work method is to process and integrate multi-source data, e.g. geological and mineral resource, geophysical and geochemical and remote sensing data, on computer and extract relevant geological information and integrate multi-source data with geological data to establish a multi-source database form a map of multi-source superimposition analysis results, which will be used in geological mapping in shallow cover areas.
