Organizations with large sets of continuously changing assets such as ProRail face the difficulty of keeping their information systems up-to-date with the actual situation in the field. Currently, they rely heavily on people who assess, measure, and photograph the situation outside, and take measures when they encounter discrepancies. This process is expensive and error-prone. The ‘Digital Survey’ project that Systems Engineering has carried out in 2012 for ProRail and RIGD-Loxia assessed the opportunity to use digital technology to increase efficiency, frequency and quality of the survey process. Four digital high-quality cameras were installed on a train, together with other measurement equipment to gather over 1 Tb of data a day about the train tracks and their surroundings. With object recognition and character recognition algorithms, GIS-technology, 2D and 3D reconstruction methods, and specially developed analysis software, the entire information chain from data gathering, through data fusion and data analysis towards data visualisation, was prototyped and analysed. The project concluded that digital surveying is possible and attractive, but that solutions for managing ‘big data’ have to be applied to deal with the vast amounts of information.
