European Union FP7 APhoRISM project proposes the development and testing of two new methods to combine Earth Observation satellite data from different sensors and ground data. The aim is to demonstrate that this two types of data, appropriately managed and integrated, can provide new improved Copernicus Emergency products useful for seismic and volcanic crisis management. The first method, APE -A Priori information for Earthquake damage mapping, concerns the generation of maps to address the detection and estimate of damage caused by a seismic event. The novelty of APE relies on the exploitation of a priori information derived by InSAR time series to measure surface movements, shake maps obtained from seismological data, and buildings vulnerability information. The second method, MACE -Multi-platform volcanic Ash Cloud Estimation, concerns the exploitation of GEO sensor platform, LEO satellite sensors and ground measures to improve the ash detection and retrieval, and to characterize the volcanic ash clouds. INGV covers the role of project coordinator and ALMA Sistemi is participating in the exploitation and dissemination of the project results.

“…However, these techniques cannot yet replace field surveys mainly because it is still necessary to balance the amount of data to collect with the computational effort related to the analysis. Web-based technologies and approaches, used as a complement to traditional field survey activities [5], can play a role in this regard [6][7][8][9]. Then, it is convenient to explore the limitations and opportunities of performing remote inspections for seismic vulnerability and condition assessment purposes.…”

On the Use of Web Mapping Platforms to Support the Seismic Vulnerability Assessment of Old Urban Areas

European countries are affected by various levels of seismic hazard, including many areas with medium to high seismicity. Heavy damage over large areas has been observed in past earthquakes in these countries, particularly in masonry buildings located in historical centers, confirming the need for enhancing the current knowledge on the seismic vulnerability of these constructions, so more informed technical and political decisions towards the mitigation of the risk can be taken. However, the characterization of building stocks for engineering purposes is still an open issue due to the enormous amount of resources that such a project would require. Nevertheless, the availability of virtual images and maps represents an outstanding opportunity for having remote approaches to urban environments. The role of on-site inspections can be complemented or even substituted by means of these remote approaches, provided it is complemented with suitable approaches. The use of these resources is not new, but the critical assessment of their capabilities and limitations deserves a critical discussion. The present paper aims at assessing the opportunities offered by web-based mapping platforms in the context of seismic vulnerability assessment of masonry buildings in old urban areas. After evaluating the advantages and shortcomings of some of the most popular web-based mapping services, an explanatory application to a set of 39 buildings located in the historic center of the city of Leiria (Portugal) is presented and critically discussed, contrasting the results obtained by using on-site and remote inspections. Two different seismic vulnerability assessment approaches are applied and analyzed herein, confirming that web-based mapping platforms can represent an efficient and cost-effective complement to traditional field surveys when the large-scale seismic vulnerability of old urban areas is of interest.

“…One major data source for documenting landscape change are 2D satellite images, especially in large-scale problems as urbanization, forest monitoring, earthquake hazard and risk assessment, etc. [ 2 , 3 , 4 , 5 , 6 , 7 ]. For these tasks, many studies used low-to-medium resolution images [ 8 , 9 , 10 , 11 , 12 ], although high resolution images were also employed for change detection at a higher level [ 13 , 14 , 15 ].…”

This paper suggests a new approach for change detection (CD) in 3D point clouds. It combines classification and CD in one step using machine learning. The point cloud data of both epochs are merged for computing features of four types: features describing the point distribution, a feature relating to relative terrain elevation, features specific for the multi-target capability of laser scanning, and features combining the point clouds of both epochs to identify the change. All these features are merged in the points and then training samples are acquired to create the model for supervised classification, which is then applied to the whole study area. The final results reach an overall accuracy of over 90% for both epochs of eight classes: lost tree, new tree, lost building, new building, changed ground, unchanged building, unchanged tree, and unchanged ground.
