Advanced Techniques in Mineral Exploration

In recent years, large and voluminous information is available on the management and use of remote sensing and GIS techniques and several websites of leading agencies are providing distinct analyses with the available geodata sets and their applications in different fields of earth sciences. There are a number of websites that deal exclusively with remote sensing studies for instances: (http://terra.nasa.gov,http://www.nima.mil, http://infoserver.ciesin.org, http://www.geographic.com, http://www.landinfo.com, http://www.grida.no, http://www.geospatial.online.com, http://www.ogis.org, http://www.asprs.org) Remote sensing is applied in the field of exploration, which directly maps the broad range of alteration minerals associated with ore deposits. Satellite systems have evolved to provide higher spatial and spectral resolutions, essential for mineral exploration. Manual interpretation of the remote sensing results on printed maps is rapidly giving way to full digital integration of data and use of Geographical Information Systems (GIS) for statistical based analysis and interpretation.
