By connecting level and GPS sensors simultaneously to Leica MobileMatriX, field crews can measure accurate locations with GPS and parallel they can update the less accurate height information with a level measured height – this process is called Height Modernization and is easily possible by the Multi-Sensor support in Leica MobileMatriX.
The Height Modernization utilizes GNSS (Global Navigation Satellite System) and TPS technology together with level instruments to improve all mapping, surveying and engineering activities and establish accurate and reliable heights – all within one mobile application. All this can be done with Leica MobileMatriX.
The following examples show the importance of robust and reliable spatial data:
- Height Modernization benefits mapping of an entire water distribution system: the objective is to know the location of every component of the system at a level of accuracy that will allow to quickly find that component (such as a valve), even if it is under water. In the past GPS, TPS and Level measurements had to be analyzed in different software packages. The combination of various sensors results lower the costs of surveying and mapping throughout the whole workflow and data analysis chain. Furthermore, it enables reliable sharing of spatial information between organizations and reduces unnecessary duplication of data while working with different sensors.
- Height Modernization benefits the determination of accurate elevations, which are absolutely essential for flood hazard mapping. In many cases, elevations must be carried over long distances for determining elevations at a particular project site where flood hazard mapping is needed. The traditional survey technique for transferring elevations such as optical Levelling are extremely post-processing-intensive and expensive. Especially combining the level and GPS measurements finally in the enterprise GIS requires many steps. This cost and workflow can be greatly reduced by using GPS and digital levels within Leica MobileMatriX with its Height Modernization functionalities.
