Agency for Natural Resources and Energy had established a newsearching system based on Web GIS, called GRIAS, Geo-Resource Information Archive System, aiming to secure mineral resources including minor metals in 2014. This project started in 2009 and had been implemented for 5 years.
GRIAS will contribute to development of minor metals with satellite images of ASTER and PALSAR data.
GRIAS allows users to search resource information and infrastructure information related to metal resource development project over the base maps of global satellite analysis images.
Then users can select and display them and make a reconnaissance survey report, study feasibility and make an investment decision.
There are well known Google Earth / Map to show global satellite images through the web. But they don't contain geological or resource information. Australian governmental organization, CSIRO operates AuScope to provide geology, soil and environmental information in Australia only. On the other hand, GRIAS's satellite analysis images cover global earth and GRIAS is focusing all contents and functions to geological and resource information to secure minor metal resource supply to Japan.
The seamless mosaic which shows Earth surface features clearly without clear scene boundaries, was compiled from ASTER and PALSAR data. ASTER and PALSAR, as Earth observing sensors, have been developed and operated by Japanese governmental organization. Further useful satellite analysis images for geology and mining exploration had been created and registered on GRIAS. User can use GRIAS with only PC and Internet access. User's request hearing and system renovation cycle had been repeated, and new contents and functions were added on in order to improve usability.
GRIAS is scheduled to start operation in 2014 to support Japan's metal developers to secure minor metal supply.
