Remotely sensed data can, in fact, provide a valuable source of broad scale information at each stage of the disaster management cycle, supporting scientists and authorities in the decision-making process. Geomatics-based procedures and techniques can be especially exploited in the emergency mapping domain for the extraction of reference (pre-event) and crisis (post-event) geographic data. The major challenges today concern the efficient selection (and integration) of the most fit-for-purpose mapping solution(s) and the development of automatic procedures to increase efficiency in data processing. This survey article provides a review of the current optical remote sensing sensors (both satellite and airborne) for rapid mapping applications. Advantages and disadvantages are evaluated in order to support the selection process of the most appropriate means to gather the required information (i. e., significant and value-added data). Since valuable information should be delivered in a very short time, the management of time is defined as a priority and several solutions are discussed to pursue efficiency in both data acquisition and processing. With this in mind, the most significant issues affecting time in each step of the work-flow and overall accuracy are analyzed and reported.

[Termes IGN] qualité des donnéesRésumé : (auteur) Despite the considerable growth in Volunteered Geographic Information (VGI) activities in citizen sensing and the evident opportunities for VGI use in map revision and updating, few European National Mapping Agencies (NMAs) or other types of government bodies have engaged significantly with VGI. Moreover, the level of engagement of NMAs with the VGI community varies greatly, and most of them have proposed their own tools for encouraging citizens and public partners to collect feedback or new data. There are numerous barriers limiting the participation of citizens and public partners in NMA data collection, including data quality issues, the motivation of the contributors and legal issues. The aim of this chapter is to give an overview of the experiences of some European NMAs in engaging with VGI. Guidelines and recommendations to support wider engagement with the VGI community are also proposed to help NMAs and interested government bodies exploit the potential of VGI for authoritative mapping.

[Termes IGN] organisme cartographique nationalRésumé : (auteur) Techniques for 3D mapping are maturing. At the same time the need for 3D data is increasing. This has pushed national (and regional) mapping agencies (NMAs) to consider extending their traditional task of providing topographic data into the third dimension. To show how research results in 3D mapping obtained over the past twenty years have been adopted by practice, this paper presents the ongoing work on 3D mapping within seven NMAs, all member of the 3D Special Interest Group of European Spatial Data Research (EuroSDR). The paper shows that some NMAs are still in the initial (experimental) phase of 3D mapping, while others have already built solid databases to maintain 2.5D and 3D topographic data covering their whole country.

Different issues need to be considered during the conception, acquisition and post-acquisition phases of VGI creation. This includes items such as collecting metadata on the volunteer, providing suitable training, giving corrective feedback during the mapping process and use of control data, among others. Two examples of VGI data collection are then considered with respect to this quality control framework, i.e. VGI data collection by National Mapping Agencies and by the most recent Geo-Wiki tool, a game called Cropland Capture. Although good practices are beginning to emerge, there is still the need for the development and sharing of best practice, especially if VGI is to be integrated with authoritative map products or used for calibration and/or validation of land cover in the future.

[Termes IGN] reconstruction 3DRésumé : (auteur) 3D technologies are becoming mature and more and more organisations are investing in 3D models for their areas. For National Mapping and Cadastral Agencies (NMCAs), that have a long history in collating and maintaining countrywide 2D-datasets, the major challenge is how to best adopt a 2D base into 3D environment with an established process of continuous incremental update, and making best use of available resources. To identify best and common practices, as well as remaining research challenges, since 2013 ten NMCAs work together in the European Spatial Data Research (EuroSDR) 3D Special Interest Group. This paper reports about an inventory that has been made on the state-of-the art of 3D products and plans that these NMCAs have as well as the challenges they face. The 3D modelling of buildings is explored in more detail, since buildings are prominent features in 3D city and landscape models. In addition, together with road objects (traffic infrastructure), building objects change often and therefore these require efficient update processes.
