The Dutch high-tech company GeoSignum has presented a new method for extracting and analysing 3D laser data on geographical features and urban structures. The new web platform called GeoSignum Pointer automates the extraction and analysis of features and objects, and uses new techniques that speed up the entire data processing workflow of 3D laser scanning data.
An entire city or hundreds of kilometres of transportation corridors, highways and railroads can be analysed and features of interest can be extracted extremely fast and converted into accurate vector models. This enables more effective monitoring of infrastructures so that problems can be found and addressed quickly.
Any company or organisation that has mobile laser scanning or airborne Lidar data, anywhere in the world, is now able to safely upload their dataset to GeoSignum pointer. Upon choosing the features that need to be detected and extracted, the system performs the process and returns the results for a final inspection. Afterwards the results can be downloaded, to be used for modelling or further analysis.
Currently the automatic feature extraction web platform (BETA) is capable of recognising and extracting railway track position, its geometry and contact wires, crash barriers from any Mobile Lidar datasets and buildings/rooftops from airborne Lidar datasets. In addition buildings can be colour-coded according to height.
GeoSignum is introducing the next-generation feature extraction solutions to the 3D laser scanning field, said Doğan Altundağ, founder of the company. Its secure and high-performance processing platform is offered as a service on the GeoSignum pointer web platform. Therefore, there is no need to buy software packages or plugins.
