Mobile Laser Scanning To Spatially Update Of City Infrastructure Networks

The city infrastructure daily development in any city/community is very huge; the huge development in the city infrastructure networks is reflected in the daily number of new installations, replacements, enforcements, etc. The daily city infrastructure utility updates are subject to maintenance and operation on frequent basis. The efficiency of the maintenance and operation workflow is strongly related to the geographical location of these city infrastructure networks. Due to the huge daily updates of the city infrastructure networks, the ability of collecting the updates locations using the current geospatial monitoring techniques is very difficult. This research is discussing a more efficient geospatial monitoring technique for the city infrastructure networks. The research will concentrate on the polyethylene city infrastructure materials, where power, water and communication networks are covered or protected by polyethylene materials. The research conducted a technical comparison between the current geospatial monitoring techniques and developed an overall performance evaluation. The mobile laser scanning technology achieved the best performance evaluation, where a detailed data analysis, data collection, mobile laser missions, modelling and interpretation, system geometrical corrections for the location and orientation also have been conducted. Prior conducting the performance evaluation, the research investigates the mobile laser behaviour and recognition capabilities with respect to polyethylene city infrastructure materials. After analyzing the mobile laser pulses behavior and its correlations with the mission ground speed and exposed scanned surface, the mobile laser pulses response constant for the polyethylene city infrastructure materials has been concluded. The concluded mobile laser pulses constant utilized to develop a mathematical model for re-planning the mobile laser scanning missions to obtain the best model for monitoring the polyethylene city infrastructure networks.
