Spatial data about telecommunication infrastructure facilities represent the inevitable resources of each telecom operator. The precision of collected spatial data, used in the geographic information system (GIS) of telecom operators, is very important, especially when it is about urban environments. In this paper, we have presented the possibility of correcting the positions of telecommunication facilities obtained using the Global Positioning System (GPS). Factors affecting the accuracy and quality of spatial data have been analyzed and solutions for quality improvement proposed. We have shown that using permanent stations can achieve the required level of spatial position correction. A fast and efficient position correction allows updating data in GIS of telecom operators, providing correct, accurate, and timely information about telecom infrastructure.
The availability of real-time data on the state of railway facilities and the state-of-the art technologies for data collection and analysis allow transition to the fourth generation maintenance. It is based on the prediction of the facility functional safety and dependability and the risk-oriented facility management. The article describes an approach to assessing the risks of hazardous facility failures using the latest digital data processing methods. The implementation of this approach will help set maintenance objectives and contribute to the efficient use of resources and the reduction of railway facility managers’ expenditures.
