Common Existing Situation

For more than one hundred years, geo-scientific data were collected on paper.

Descriptions, bore hole logs, maps and exploration reports have filled up public and non-public archives with materials of inestimable value.

The systematic capture, storage and distribution of this information is an extremely important and expensive activity.

Many database systems grew independently from each other even in one organisation. The result is a jungle of information,many redundancies and problems with sharing of information

1998: Map of Mineral Deposits KOR 50Free State of Saxony, Germany

�long-term strategic goals for aggregate mining industry: Where are our deposits ?

�Attraction of investors

� Environmentally friendly aggregate mining

� Support planning activities: land use planning, planning of infrastructure, urban development, agriculture, national parks, ...

� 1,9 Mio. inhabitants

� mainly ethnic Albanians

� under UN Administration since the Kosovo war 1999

� development of a local administration

� base metals, silver

� chromite

� Provide information to any interested party (state agencies, NGOs)

� Guarantee easy and fast availability of data � internet� Create important pre-requisites for complex land use and infrastructure planning:

� geology� hydrogeology

� minerals� geo-hazards� soils

� contaminations,…2003 - 2006

Experiences

Is there an universal information system: NO !

� the general structure of an IMS is always similar: database, GIS, and unstructured information, but

� local limitations, regulations, and pre-existing features require in almost all cases a tailor-made system designand programming, and

� the very fast development of information technologies requires the adjustment of developed systems as well
