Fields of Application

• Canal land register
  The self-check regulation governs the documentation and remediation duty of the operator – on the other hand, the water supply and sewage disposal, documented on the basis of the private house and fields maps, describes important sources of public authorities’ income. Alongside the official data of the fields map, all shaft and block data in location and height and also in three-dimensional form must be made available in the Gauß-Krüger coordinate system.
• Line land register
  Civil engineering works often cause damage to lines if a survey map fails to list installed electricity, telephone and water lines. The resulting costs are immense and can be avoided by using an up-to-date, nationwide line land register.

  Sealing surfaces
  A comprehensible investigation of built-up areas is required for a legally secure calculation of charges, for which the cost of the canal fees is not only based on the amount of fresh water used but also on the amount of precipitation, requiring fixed areas in the sewerage system. However, the planning of rain retention basins also benefits from exact data on the sealed surfaces in the catchment area. “The less concrete installed, the lower the cost”, according to experience from a project in the Ruhr.
• Areas of flooding
  In order to prevent catastrophes, the causes of flooding must be investigated, repercussions determined and countermeasures introduced. Therefore areas of flooding should be officially determined and specified, and results regarding restrictions of use should be derived. Sufficiently accurate topographical documents and plans are required to designate them, i.e. terrain morphology and infrastructure are measured with an accuracy of < 10cm, use is also recorded.
• Forest , biotope and green area land registers
  Within the framework of planning and decision-making processes in connection with urban planning/development, current information on the availability of individual and stocks of trees, green areas or biotopes is an important foundation for planning. For this task, CIR aerial photos are mostly used. The different reflexion behaviour of the vegetation in the infrared range also enable the vitality of a tree to be determined.

  Contamination site land register
  An area of new development turns out to be a former poisonous substances dumping site or, as in Ingolstadt, a former armament site. In any case, good advice is expensive here – it is better for the planning to take the existing danger of pollution in the ground or ground water into consideration beforehand. A contamination site land register helps in the up-to-date processing and remediation of such sites, and simultaneous documentation protects against incorrect planning. As a special tool in dealing with contamination sites, the multi-temporal aerial photo analysis provides information on the history and former uses of a site.
• Disposal site measurement
  Aerial photo measurement is the innovative solution for recording the topography of disposal sites. On the basis of a digital terrain models (DGM), the surface is represented three-dimensionally. The DGM forms the basis for the calculation of disposal site and backfilling volumes and the deduction of profiles at any point. It is indispensable for continual planning.
• Radar planning
  Digital town models are created using photogrammetry and geoinformation systems as a basis for dispersion calculations, e.g. in mobile communications planning. The aim is to process geometric 3D data within urban areas as a basis for dispersion calculations to optimise antenna sites and radio cells with an accuracy in the range of +/- 0.5m.

  Monitoring forests/recultivation
  Monitoring forests/recultivation
  Remote sensing data and ground measurements are used for monitoring forest areas. SAR/InSAR technology, HRSC or LIDAR data as well as multi or hyper spectral data can be consulted to determine the forest and its properties.
• Determination of forest biomass
  In the SAR/InSAR technology, the microwaves in the P-band frequency range penetrate the vegetation. Height models derived from this display the height of the forest floor. The measurements in the X-band frequency range produce a surface model and thus the height of the tree stock. The biomass can be calculated from the difference between the two models. The same can be achieved with LIDAR data
• Detection of concealed objects and contaminated sites
  In the weather-independent SAR/InSAR technology used, the microwaves in the P-band frequency range penetrate the vegetation and facilitate the detection of objects in dense or primeval forests. On land without trees, the P-band microwaves penetrate the soil up to a depth of 20m depending on the consistency of the soil.
  Aerogeophysics methods and soil-supported geophysics measuring methods mean that bomb duds, munitions (UXO) contamination sites can be detected.
• Erosion danger
  Digital terrain models and ground measurements are important input data for the simulation and model calculations for determining areas in danger of erosion. Multi and hyper spectral data, thermal infrared images and orthophotos enable or support mapping of these areas and can contribute to minimising field work and controls. These simulations and evaluations are used to derive measures for avoiding erosion-related environmental damage.
• Land and vegetation mapping
  High-resolution multi-spectral data of a HRSC system (pixel size 0.5m), but also that, for example, in the 128 spectral channels of the hyperspectral scanner HyMap (pixel size 4.5m) highly differentiated photographed spectral properties of the earth’s surface are used in the ENVI and ERDAS Imagine analysis systems, to create detailed land use and vegetation mappings.
