Moskito Geo-Informations-Systeme GmbH is an established IT-based geographic information system manufacturer located in Dortmund.

The company was founded in 1997 by two computer scientists, Horst Wessel and Hans-Josef Hoebertz. Today it has seven employees.


The team includes graduated computer scientists, mechanical engineers, surveying technicians, and spatial planners.

With ingenuity and their ability to think outside the box, they work on ideas and new concepts that significantly exceed the limits of traditional geographic information systems.


Every year, with one of our customers, we organize the Moskito User Conference, and all our users are invited. On this day, in addition to the presentations of new developments, there is always a supporting program to have an exchange of ideas with our customers about future requirements and receive feedback on the quality and quantity of cooperation in the past year.

We are currently concentrating on developing a web-based and offline-capable tree cadastre Moskito"ProBaum" for municipalities. We want to make Moskito more intuitive and improve the user interface soon. We even offer our customers more new functions and individual products, which are tailored to their needs specifically. The next development plan integrates the Moskito GIS with Building Information Management (BIM) to link up a large-scale administration and information with buildings.

We regularly participate in the annual Intergeo trade fair, where we will be happy to inform you about our products at our stand and advise you based on your requirements.

The beginnings of Moskito

The Moskito GIS Company was founded in 1997 by computer scientists Hans Josef Hoebertz and Horst Wessel.

From that time, it had already been two years invested into the development of the software, originally developed as a PC version of the Großrechner-GIS "GRATIS 2000". The Strässle company system, which Wessel and Hoebertz had been helped to develop, has a development history that goes back to the 1970s.

In this way, the new Moskito-System has benefited from many years of experience of GRATIS to supply in the user market quickly. Following the Strässle company's closure in 1995, the Moskito GIS has been developed as an independent software regardless of GRATIS and marketed.

In the beginning, the Moskito GIS had been managed and developed solely by Hoebertz and Wessel, who were owners and managing directors equally. After the system was used in the first companies, more developers were hired.

Projects and changes

Moskito company has continued to develop itself over the years and employed up to 15 people full time. Due to the tragic accidental death of the managing director and owner Hans Josef Hoebertz, some significant changes occurred in the company in 2007. Sometime later, Horst Wessel took over the role of sole management and had to redistribute the company's tasks.

Moskito was involved in the German-Vietnamese wastewater research project "IWRM." In long-term cooperation with the German universities in Bonn, Bochum, and Greifswald and Vietnamese universities in Can Tho, Da Nang, and Hanoi, the wastewater management project in the Tropics and Subtropics of Vietnam was optimized. In many individual projects, a water quality analysis of the Mekong was carried out, and a water treatment system was built up in a heavily polluted industrial area.

Due to the language barriers within the project, Moskito and its employees learned a lot about communication management during this time. Also, the user interface of Moskito had been considerably optimized during this time so that the project participants with less GIS experience could work more efficiently with the applications.

Application areas and customers

The Moskito GIS is also specially optimized for network operation, and today many big energy providers and small and large industrial enterprises are a user of Mokito GIS. Moskito's first customer in 1996 was NTS company in Münster city, and they have been using the Moskito GIS products today. Other customers are the energy supplier such as Syna and RWE, which operates more than 30 workstations for initial data acquisition and network changes at peak times. The RWE now mainly uses Moskito in the power plant area. Other companies that also use Moskito included SMS Meer, Evonik, and Eurogate. Our applications are compatible with internal systems and can be integrated into company structures with the required security.

Over the past two decades, Moskito has been continuously developed based on the user's requirements. In the early years, the system was mainly used to optimize the utility sector's highly optimized digitization of supply networks. For this purpose, the data was captured in large teams by using digitizing tablets. Since then, Moskito has increasingly switched into a screen application. While GIS experts wanted to use the program over time, Moskito GIS has been tried to provide simpler interfaces, which helps other users work efficiently with the Moskito GIS.

The developers of Moskito always endeavor to assess developments among the users at an early stage and to have products as early as possible under development or finished when our customers need them.
