Martina Busch und Ulrike Schwarz: Ein Team für schwere Fälle

The communication for the city council Muelheim an der Ruhr in June 2013 comprises around 1.200 pages. More than 500 pages are filled with the answers to the public’s ideas and suggestions, 14 expert opinions and three public hearings were necessary.

In any case the work of art is a success against the strongest resistance of those people, who saw the decline of the town or at least its suffocation by some 20 new houses. “We are not allowed to make any mistake, neither a technical nor a juridical mistake” says Ass. Busch, “in GEOHAUS we have got a good overview over all details of a B-Plan-development procedure. That is why we can solve the detail question targeted. We have the experience of a series of most complicated procedures to install such legally binding land use plans.

The biggest B-Plan, GEOHAUS has ever developed, were a 900 ha holiday resort, a 65 ha B-Plan for commercial use with heavy industrial backlogs or a 51 ha area for living with a total land consolidation.



A group of technicians met in the List – Centre in Wegberg-Wildenrath on april 16 discussing the new project GALIL-EU.  The rail track of RailGate as a topological quasi-invariant of space was the item of interest. The two big test stations RailGate for railroad vehicles and AutomotiveGate for road vehicles will in future become also a scientific place, a test and calibration station for highly accurate geodetic methods and tools.

Dr. Klaus Deininger, Lead economist of the Worldbank, lead the conference “On Land and Poverty” from april 8 to 11 in Washington to a further high water mark. Four sessions per day in six rooms parallel, each session with 4 – 5 lectures documented breadth and draught of the landmanagement in the developing countries around the world. Hansa Luftbild presented its cadastral project in Addis Ababa, held by Berisso Zerihun (Addis Ababa City) and Tarek Zein (Hansa Luftbild AG).
Dr. Otmar Schuster chaired the session “New Challenges for Land Administration” with the authors: Mogues Tewodaj (International Food Policy Research Institute), Dr. John Bruce (LADSI Inc, USA), Jorge Espinoza (University of Munich) and Prof. Eric Abbot (School of Journalism and Communication, Iowa). Often we have the impression, as if the events happening are stronger than the good will of the majority; but the progress is visible: The scale of responsibility shows upwards, the transparency of all measures, powered by the internet, reduces the role of corruption; the role of the women is more and more important.
What is the contribution of GEOHAUS to the international land management? The combination of technology and law for the development of fully operational real estate markets.
Dr. Klaus Deininger, truly in his element


Das Reichsgericht in Leipzig

The new book “Über den Dächern von Leipzig - Over the roofs of Leipzig”, 2nd edition 2013, published by Lehmstedt, is an uniquely illustrative work about the development of a town in that time. The aerial photographs most come from our Hansa Luftbild or from Junkers Luftbild.

The editor is Peter Brogiato. With the accompanying scientific text and the afterword from Dr. Matthias Meusch, it shows the upper class Leipzig as well as the progressive quarters, built to fight the housing shortage in these years. The Second World War and the socialist period destroyed a lot. But now the city of Leipzig found back to its old quality of town building.



The photo – grey in grey – shows a scan of an inaccessible space in an old public building. It reveals information concerning the geometry of these spaces.

Over a small opening the spaces are connected with outdoors. By a special Geohaus-device we succeeded to make the spaces three-dimensionally visible. Every point of the cloud gets an absolute coordinate. So theses spaces can get cm-sharp  positions in the architectural designs.


The topics infrastructure, disaster management, coastal survey and border control were discussed on a delegation trip to DELHI under the Parliamentary Secretary of State Otto, Federal Ministry of economy and Technology from 8th to 14th January 2013.

High level personalities coming from the Indian state, management and technique were the discussion partners. The German delegation consisted of key representatives of the German industry and trade, but they came also from research organizations, from the GIZ. Managers of the German fair organizations, the fire brigades played an important role. For the German Geo-information GEOHAUS and HANSA LUFTBILD  AG were invited to join.

Whilst the German industry is well known in India and has good opportunities, the Indian partners were interested in the German voluntary based fire brigades and the overall scheme of the German geo-information.

The  first generation of „GEObox smart“, produced by GEOsat (www.geosat.de), carried out their duties without any failure or maintenance in the construction site vehicles under ruggedized conditions.

The software coupled the location data with the order data for secure invoicing towards the client. Order management and field staff documented their competence.

Our partners at the construction site could recourse to this information, which has often proved to be very useful.

The new “Geobox smart” impresses by higher data security in cases of a lack of server or internet connection. The automatic evaluation of date is easier.



Hans Oberscheid (93), self employed farmer in Duisburg, is feared and admired in the public building authorities. Being more than 70 years self-employed, his experiences as honorary judge at the Agricultural Chamber and his experiences with his real estate taught him not to give up, use his clear brain, have a clear look upon the interests of his opponents to reach his goal. Recently, having lost a crazy suit case at the Regional Administrative Tribunal concerning four garages moved by him from one place to the next, he did not allow himself to be kept from going into the next instance (“the Regional Court in the first instance decide always in favor of the public authority!”). After the judge’s decision at the higher court, he won at the Regional Court, based on the GEOHAUS – consulting, which he early had acknowledged to be right.


The implementation of the legal coordinate cadastre brings up the question in the daily practice, where is the right place for border stones, if the coordinate of “highest accuracy” differs from its demarcation.

The cadastral material in form of sketches has grown over 200 years. This is the reason why every point has a more or less big area of tolerance. If a border demarcation is laying inside that area of tolerance, and if it was acknowledged by the former neighbors, when the border point was installed, then its site cannot be refused statistically.

Its site can only be shifted in that case, if the neighbors confirm that in an official protocol. And even in such a case the shift of the stone must be within the tolerance area. Consequently the Cadastral Authority of Muelheim at the Ruhr has downgraded all its coordinates of highest quality to avoid legal uncertainties by the legal coordinate cadastre. The normal citizen can hardly understand the facts, even if the consequences can be very far-reaching.


To ease the situation for the citizens the Public Appointed Surveyors in GEOHAUS are called upon to give more information in the topological sketches belonging to the official protocol in form of relative measures to walls or other topographical features. They help the neighbors to have a better orientation about the legal site of the border and the border points.
