Technical detailsThe Greek site under investigation is located in the region of Kalochori close to Thessaloniki port in North Greece, presenting great scientific and monitoring interest related to the examined natural hazards, thereby in agreement with the general objectives of the project. The integrated nature of the monitoring scheme is provided by a combination of two Airborne Lidar Leica ALS60 missions for change detection purposes and production of an accurate 3D city model combined with the town planning data of the constructions in the urban, industrial, gas and oil tanks area next to the port, Airborne DMC frame camera RGBNIR data at 0.10 cm ortho production, mobile GNSS stations, a tide gauge and water level sensors for ground subsidence measurements complemented by permanent seven accelerographic and two GNSS stations for monitoring seismic motion. The above multi-sensor scheme is deployed as an innovative pilot study, based on available means, in properly selected urban site. Besides monitoring and data processing, soil subsidence and seismic motion are being investigated by means of pertinent methods of analysis that will be developed and adapted in an urban-scale sense aiming at a better understanding of the investigated hazard sources as affected by the urban environment. Both recorded data and analysis predictions are integrated, combined and implemented towards the development of a research tool and they are made readily-available and accessible to the scientific community and local/national decision-making authorities through a properly designed Web GIS platform.
