The precise recording of geodata plays a central role in the district of Kulmbach – whether in the management of street trees or in landfill operations. In order to obtain reliable position data at all times, the district office relies on the mobile GNSS receiver ppm10xx. The handy device enables flexible and precise surveying directly on site – even under difficult conditions such as dense vegetation or in deep trenches. This makes digital infrastructure maintenance more efficient and user-friendly.
Local authorities rely on precise geodata to reliably document, maintain and expand their infrastructure. The Upper Franconian district of Kulmbach uses two GNSS receivers from ppm GmbH for this purpose.
These high-precision instruments can process the signals from several global navigation satellite systems (GNSS) simultaneously. This means that a sufficiently strong signal is available even in areas with potential shadowing effects, such as in narrow street canyons, under leafy trees or in trenches. This enables position data to be recorded with centimeter accuracy, almost anywhere and at any time.
Digital tree cadastre for road maintenance
The road maintenance department uses a ppm10xx zero GNSS sensor, which can be connected wirelessly to a tablet PC via Bluetooth. Among other things, the device is used to precisely record the locations of trees along the district roads. The aim is to clearly document who is responsible for the road safety of these trees.
Above all, this should help to avoid legal disputes, for example when trees have to be felled or pruned that may be on private property. All recorded position data is incorporated into a digital tree register. While such a register previously only existed for district-owned properties, the trees along the district roads are now also systematically measured and recorded.
Precise work at the DK 0 landfill site in Kirchleus
The ppm10xx GNSS sensor is used in conjunction with a bulldozer at the Kirchleus landfill association to control the application and removal of material during ongoing landfill operations. A GNSS antenna was mounted on the roof of the machine for this purpose. This continuously receives signals from all satellite navigation systems, such as GPS, GLONASS, BeiDou and Galileo.
Der ppm10xx GNSS Sensor lässt sich schnell und unkompliziert in der Kabine anbringen.
The ppm10xx GNSS sensor can be installed quickly and easily in the cab.
This technology allows the exact position and height of the crawler to be determined in real time – to within a few centimetres. The operator on the crawler uses the GNSS data and a digital terrain model (DTM) of the target heights to know exactly where material can still be added or where too much has already been added. This ensures compliance with the specified target height profiles and terrain shapes.
The push crawler equipped with the sensor thus replaces time-consuming, infrequent and expensive intermediate surveys between the official annual surveys by external surveying offices.
Maximum flexibility thanks to modern GNSS technology
The various possible applications illustrate the flexibility of the ppm10xx GNSS sensor: it can be used in municipal administration wherever precise geodata is required.
In addition to its technical performance, the ppm10xx GNSS sensor impresses with its ease of use. “The ppm10xx GNSS sensor can also be used without surveying training. This means that all of our employees can record position data themselves without having to commission external surveying offices,” explains Julia Maisel from the Kulmbach district’s mobility and GIS management team.
The combination of high precision, easy handling and flexible usability makes the ppm10xx GNSS sensor a valuable tool for municipal administration. With its use, the district of Kulmbach demonstrates how modern GNSS technology can make administrative processes more efficient and optimize them.
