Objectives, Work Packages, Results

Added value for industry, science and the region


  • Sustainably protect Saxon raw materials data against loss, corruption and oblivion
  • Make digital data available to industry, science and administration
  • Provide data for reinterpretation
  • Pass on the savings potential through the use of data in exploration and investigation
  • Strengthen the geomining location of Saxony
  • Expand the data processing systems and databases of the LfULG in its function as state geological service.

Work packages

To efficiently achieve the objectives, the ROHSA 3 project has been split into four work packages:

Work package 1: DP activities and adjustments

Applicable to all data:

  • When gathered and prior to issue, all data and each archive information, respectively, has to be checked in terms of data privacy. This is why such information is released successively.

Work package 2:  Archive searching

Documents kept at different archives and collections are sifted and secured. The focus is on metadata acquisition, digitization and access to the extent permitted by law.

Work package 3: Collecting raw materials data in databases

This work package makes the data stock accessible.  All relevant point data (e.g. borehole or sampling locations) from relevant documents or digital files are collected and transferred to the central exploration database of the LfULG. Scans of area data, such as maps orplans, are georeferenced to be able to show and evaluate them by means of geoinformation systems.

Work package 4: Scientific results

This package is dedicated to publications making the findings accessible to the public.

A case in point is a 3-D model of the geological sub-surface and a raw material forecast created in cooperation with partners from science and industry.


The merging, digitization and publication of raw material-related information covering several centuries are for the benefit of science and industry.

Since 2013 previously unpublished documents from the following archives have been screened and gathered:

  • Geological archive of the LfULG (mainly reports, maps, files, boreholes),
  • Archive of State Mining Authority (plans, maps),
  • Geological archive of Wismut GmbH (boreholes),
  • Archive of the Federal Institute for Geoscience and Natural Resources (Bundesanstalt für Geowissenschaften und Rohstoffe (BGR),
  • Archives of  institutes of the TU Bergakademie Freiberg (unpublished qualification work, documentation of specimens and rock cross sections),
  • Saxon mining archive (search, appraisal, documentation of ROHSA3related data stock).

Scope of collection:

  • About 45,000 individual documents covering about 2.7 million archive pages have been scanned.
  • About 630 ore drills by Wismut GmbH have been digitized and about 538,000 geophysical and about 240,000 geochemical data points secured.
  • More than 10,300 reference data points (metadata) of documents, reports, qualification work etc. have been collected from the a.m. archives. The data of the SMUL library network can be searched online since August 2016.

Examples of application

  • Geological 3D model: A 3D model has been prepared for a section of the area. It illustrates the usability of the data.
  • Prognosis of prospects: The prognosis software advangeo® was used to create a raw material prognosis. The prospect of certain raw materials can thus be estimated. A prospect is an area where it is likely that deposits of certain raw materials can be expected.

Various tools are available for the search for raw material-related data in Saxony.

ROHSA search engine
It is a search engine specially designed by HP (HP-IDOL) for the ROHSA3 project. By entering any kind of search term, searches for raw materials data can be performed. The search results can be narrowed down by adjustable filters.

The Web-OPAC (Online-Public-Access-Catalogue) contains the media of the specialist libraries of the Saxon State Ministry of the Environment and Agriculture and the geological archive of the Saxon State Office of Environment, Agriculture and Geology.

Kitodo (formerly Goobi e.V.) enables workflow control and collection of metadata in mass digitization. Currently, this tool can be used to search and display the digital data stock  of the Saxon State and University Library Dresden (Sächsische Landesbibliothek  - Staats- und Universitätsbiobliothen, Dresden (SLUB)).

TerraCatalog – GeoMIS-Sachsen
GeoMIS-Sachsen can be used to specifically search for digital maps (georesources). The search interface is based on the smart.finder SDI® (terraCatalog) by Con.Terra. Search queries always deliver at least the metadata of the maps searched for. To some extent, the search result provides direct access to the requested maps.

Exploration database
Geological outcrops in Saxony are managed in the exploration database of the LfULG. They can be viewed and selected by means of an interactive map. It is also possible to integrate the maps in GIS applications.
