geo-institut:
tradition in the second generation

geo-institut’s “birthplace”

1948

„Geoplastische Verlag Ernst Knoll“ was founded in Vlotho/Weser (Germany). The production of the first 3D relief maps made out of plaster started.

1952

The entire manufacturing was adapted: rubber was used instead of plaster for the production. From this time on, relief maps were rollable and could be transported and stored in the schools more easily. Plasters made maps, as well as, rubber made maps were painted in manual labour.

1956

The development came to a crucial point: Plastic foils instead of rubber were used. Thereby, the entire production technique had to be shifted again. Different areas for the drawing, screen-printing and synthetic deformation had to be equipped. Due to this new technique, production numbers and quality multiplied.

1969

The company moved into the new building in Porta Westfalica and the companies name was changed into “Relief-Technik”. The longstanding development of the relief globe began, that means, extracts were drawn, moulds made, and various tests made.

1982

The management was passed on to Ernst Knoll’s daughter Irmela and son-in-law Hermann Muermann. With this generation change the company “Relief Technik” was passed on to the “Geo-Institut”. In the following years, the development of relief globes was continued and lead to success. The overall development time until today’s state of the art lasted for more than a decade.

1993

The drawing, which was done only analogue up to that time, was computerised. A photo laboratory, which was equipped allowed for the production of topographic maps of districts, as well as, municipalities in a limited edition and even as unique copies.
