GIS Andes

GIS Andes is a homogeneous information system of the entire Andes Cordillera, covering an area of almost 4 million km2 and extending for some 8,500 km from the Guajira Peninsula in northern Colombia to Tierra del Fuego in southern Argentina. Conceived as a tool for both the mining sector (as an aid to minerals exploration), and the academic sector (as an aid to developing new metallogenic models), GIS Andes is based on original syntheses and compilations.

The system comprises geographical, geological, metallogenic, geophysical layers and metadata:

GIS Andes

GIS Andes is the first of a series of computerised geological mapping systems from brgm . After more than four years of development, the range of information included in the product make it an essential tool for anyone investigating the geology of the Andean Cordillera, whether for the mining sector or for the academic sector.

GIS Andes also includes over 10,000 fault lines, 7,000 towns/ villages, 500 airports and all major rail and power networks as well as the roads and rivers and the Cordillera. GIS Andes has the ability to zoom from a scale of 1:37 million to a scale of 1:100,000.

Whilst GIS Andes is a powerful tool, it is also very simple to operate. With ten distinct sections (new version), you can cross-reference geology, geography, mineral deposits, fault lines and other data in a host of ways to exploit fully the information available, before committing to costly exploration.

Two levels of geology have been integrated into GIS Andes:

A detailed geological map of the Cordillera with consistent geological representation can be viewed with or without mineral deposits, and with or without part of the geographical layer, to aid with identifying known mineral occurrences and with the logistics involved in visiting sites. In addition to this, a summarised geological map has been developed to show the broad trends across the Cordillera. This can be used to assess large-scale structures, to analyse regional faulting and to aid with orientating before detailed study.

Over 3,300 mines and mineral deposits, as well as indicator rocks associated with gold mineralisation, can be displayed in conjunction with the geological layers, and with the major geographical structures. Information is displayed on-screen for each of these occurrences and, in addition, there is a bibliography of individual references from third-party sources.
