TRIGIS manages your geodata, quickly, inexpensively and online.

Primarily for supply and disposal companies, but also for large-scale geographical analyses - TRIGIS has many years of experience in the GIS sector.
We procure, manage and refine your geodata.


The TRIGIS WEB MAP (TWM) Internet-based geographic information system was specially developed for the requirements of municipalities and public contracting entities. It is used to digitally record, evaluate and easily administrate all important infrastructural and geographic conditions.

TWM facilitates electronic data transfer between communities, special purpose associations and the administrative district office, and enables online access of data from various authorities and ministries.

Safeguarding the future and data

TRIGIS provides the system and stores, secures and archives geographic data. The data is stored in OGC data formats to enable continuing use of all data in the event of a future system change. Access to all data is encrypted and all current security standards are filled.

Insight into the TWM

Insight into the TWM

Parcel search made easy: With the address module, German and international communities can view and manage their parcel maps. In addition, the owner retrieval can be activated for authorized users. Information recorded by the authorities, such as building perimeters, "actual use" or boundary points, can be added separately.

Extract from the tree module

Extract from the tree module

In this 3D view a part of the tree population of this municipality is shown. Each individual tree can be categorized according to its characteristics. In the map, visual differentiation is made by size and coniferous or deciduous tree. Detailed factual data as well as control dates can be documented in the subject tray.

Extract from the Street Inventory module

Extract from the Street Inventory module

In this module, the process chains from dispositions (dedication, reclassification, etc.) to entries in the inventory can be made. Colour-coded streets visualise the valid type of street class. The practical document export allows you to conveniently print out and file all relevant information, always up-to-date. (Background map: OSM)

In the supply and disposal modules sewer, water and gas you can document and maintain your complete network. The data from the water module presented in this image show the drinking water connections of the village of Thannhausen. If you move from the overview map to street level, you can differentiate between supply lines, house connections, tapping sleeves and hydrants. For the latter, an excerpt from the tray is shown as an example. Using the 3D option, the supply networks can also be displayed in space.
Excerpt from the green spaces and playground modules

Excerpt from the green spaces and playground modules

The areas show the different categories of green spaces, while the individual symbols indicate the playground inventory. Hatched areas give an indication of the next inspection date. Details of the selected swing can be directly viewed or edited via the tray (on the right of the image).

Digital terrain and surface models

Digital terrain models and digital surface models are created by TRIGIS according to strict accuracy requirements.

Production is fully and partially automated.

A digital terrain model (DTM) uses a dot matrix to describe the terrain surface. The position and elevation of each dot are known.

A digital surface model (DSM) describes the Earth’s surface, vegetation and building development using three-dimensional coordinates of ground and non-ground points. It is generated using echo points of airborne laser scanning.


In cooperation with GeoFly GmbH, TRIGIS offers:

  • Contour maps
  • Slope maps
  • Line-of-greatest-slope vectors
  • Perspectives
  • Visibility maps
  • Cross-sections
  • Erosion risk maps
  • Volume determination
  • Shading

The digital models are used in the following areas:

  • Agriculture and forest management
  • Disaster control
  • Archaeology
  • Noise control
  • Environmental protection
  • Radio network planning
  • Flood control

Municipal base maps

TRIGIS has over 20 years’ worth of expertise in the creation of municipal base maps.

A municipal base map contains all elements of the land register map, as well as comprehensive and detailed topographical components. This structured topography is standardized and describes routes, slopes, detailed representations of trees, street furniture such as lampposts, manhole covers, transformer stations, and much more.


  • Planning tasks
  • Economy
  • Municipal authorities (planning permissions, zoning maps)


In cooperation with GeoFly GmbH, TRIGIS offers:

  • Aerial photography flights
  • Creation of city base map
  • Thematic maps and analyses (vegetation analyses, route analyses, etc.)

Tree registers

Communal and also other green areas accessible to the public are subject to obligatory traffic safety. This includes controlling the tree population at regular intervals and documenting the controls.

The Research Association for Landscape Development and Landscape Gardening (FLL), as a recognized standards committee, has developed guidelines for the control and care of trees. Since liability insurers are oriented primarily to the FLL guidelines, these have become established as the state of technology.

TRIGIS supports you with the construction of an FLL-conformant tree register, including mobile solution, reporting and local professional service offers in connection with tree experts, according to FLL.
