Remote sensing, photogrammetry, geostatistics and mapping

We deliver aerial and satellite imagery as a key component of remote sensing.

Every tourist knows about this. You climb onto an exposed viewing point and within a few seconds, the landscape opens up before your eyes. This is where remote sensing starts. The earth’s surface is observed from a high altitude through aerial and satellite remote sensing, measuring the reflected electromagnetic radiation – in the simplest case, the visible light. Depending on the height of observation and the sensor system, remote sensing can deliver a multitude of information. Covering large areas and being readily available, remote sensing is suitable for different user groups and a diverse range of fields of application.

Whether satellite, aircraft, unmanned aerial vehicle (UAV), optical sensor or radar sensor – we configure and find the perfect remote sensing system for your specific application. We plan the flight mission and the satellite tasking and organise the data acquisition. We transform the raw data of aerial photographs and satellite images into digitally usable and geocoded information that fits perfectly into the map projection of your choice. Radiometric and geometric distortions and atmospheric noise are eliminated.

We create new geoinformation.

Aerial and satellite remote sensing imagery contains a multitude of geometric, physical, biological and social information. We identify the added value of geoinformation (objects, areas, units etc.) that you need. This also counts for its spatial and temporal relationships. Depending on the specific task, we offer geoinformation with different degrees of automation using other types of spatial and ancillary data and different GeoIT techniques.

Classification: We classify data, i.e. we subdivide the remote sensing imagery into useful segments.

Photogrammetry: We use remote sensing imagery, taken from different perspectives, to generate 3D data based on the principle of human spatial vision.

Data science: We combine geoinformation to create new geoinformation.

Cartography: We produce cartographic geoinformation products.

We map on site.

Remote sensing can cover a large number of tasks. On-site mapping by field staff will continue to remain important for the collection of in-situ reference data in order to calibrate, verify and validate mapping and monitoring results from remote sensing data, as well as for the enhancement of geoinformation with detailed knowledge as well as the fulfilment of legal requirements.

Field observations – complementary to remote sensing – are among our core areas of expertise. Our field staff use cutting-edge positioning and communication technologies and mobile GIS solutions to collect ground data.

We harness the services of a proven Europe-wide network of experienced freelance surveyors and business partners. We offer consulting, planning and implementation – all fast and reliable.

We integrate geoinformation.

Geoinformation is not just geoinformation. You know it from day-to-day use of IT. There are various formats, protocols and other interfaces that often do not harmonise across systems. With geoinformation, this is often exacerbated by the spatial reference of the data within different map projection systems.

We prepare the information in such a way that it meets the requirements. We convert and transform the data. We harmonise and migrate entire geoinformation databases. We have a comprehensive knowledge of all standards and de-facto standards such as OGC (Open Geospatial Consortium) and ISO. We work in accordance with the legal requirements arising from the EU INSPIRE (INfrastructure for SPatial InfoRmation in Europe) directive.

We compile existing geoinformation.

There is no need to reinvent the wheel. Think of “big data”. There are now countless sources of geoinformation. There are also efforts to standardise research and acquisition of geodata infrastructure. We have an extensive understanding of data archives, official geodata and other sources of data. We search existing geoinformation and provide you with the data you need.


We use multiple data sources for geostatistical analyses.

Geostatistics is the discipline of using statistics to analyse geospatial data. We integrate remote sensing, on-site mapping, surveys and other data sources into geospatial data analyses. When necessary, social media and smart devices are incorporated, too.
