| Namibia
looks back over a history of more than one hundred years of mineral
investigation and geological research. Mining companies and the
government spent billions of dollars on geo¬logical investigations
carried out in the country. The results of these are contained in
thousands of files, maps and reports housed by the Geological Survey
of Namibia (GSN) archive in Windhoek. Previously the public and
GSN staff had access to these unique and mostly irreplaceable documents,
but deterioration of the partly very old material made its conversion
into digital format desirable. GSN is currently busy scanning this
archival information and make it accessible through the Earth Data
Namibia database.
The
Earth Data Namibia
project started in 2001, with scientists of the Economic and Regional
Geology Divisions, in cooperation BEAK Consultants of Freiberg/Germany,
designing the database. Funding for this project was obtained from
the Minerals Development Fund as well as the government. Earth Data
Namibia is a customized software, managing geological and related
data held by the Geological Survey of Namibia. It is designed as
a client-server-solution within the local area network of the GSN,
both for internal use and as a tool to disseminate open-file mineral
exploration data and other geological data to the public. At present
Earth Data Namibia contains spatial and factual data on mineral
deposits and occurrences, exploration and mining licences, drilling,
geochemistry, geological reports, maps and other printed material,
as well as related topographic and topocadastral information (e.g.
farms, roads), together with metadata about scanned archival documents.
To store and manage this factual, geometrical and unstructured information
the data base uses ORACLE and ARCVIEW as platforms. User-generated
maps (showing for instance geochemical data on a regional geology
backdrop) can be printed out as hardcopies or saved as printfiles
through an automated map
layout facility. ARCVIEW Earth Data Namibia forms part of the
GSN’s strategy to standardize the process of data collection
and facilitate easy accessibility and recovery of information related
to the natural resources of the country. |
