[Termes IGN] trait de côteRésumé : (auteur) Interaction between land subsidence and sea level rise (SLR) increases the hazard in coastal areas, mainly for deltas, characterized by flat topography and with great social, ecological, and economic value. Coastal areas need continuous monitoring as a support for human intervention to reduce the hazard. Po River Delta (PRD, northern Italy) in the past was affected by high values of artificial land subsidence: even if at low rates, anthropogenic settlements are currently still in progress and produce an increase of hydraulic risk due to the loss of surface elevation both of ground and levees. Many authors have provided scenarios for the next decades with increased flooding in densely populated areas. In this work, a contribution to the understanding future scenarios based on the morphological changes that occurred in the last century on the PRD coastal area is provided: planimetric variations are reconstructed using two archival cartographies (1911 and 1924), 12 multi-temporal high-resolution aerial photogrammetric surveys (1933, 1944, 1949, 1955, 1962, 1969, 1977, 1983, 1990, 1999, 2008, and 2014), and four LiDAR (light detection and ranging) datasets (acquired in 2006, 2009, 2012, and 2018): obtained results, in terms of emerged surfaces variations, are linked to the available land subsidence rates (provided by leveling, GPS—global positioning system, and SAR—synthetic aperture radar data) and to the expected SLR values, to perform scenarios of the area by 2100: results of this work will be useful to mitigate the hazard by increasing defense systems and preventing the risk of widespread flooding.

[Termes IGN] Yvelines (78)Résumé : (auteur) Avec le nivellement Bourdalouë effectué entre 1857 et 1864, puis le nivellement Lallemand commencé dans les années 1880, la deuxième moitié du 19e siècle est incontestablement l’époque pionnière du nivellement général de la France. Mais c’est aussi le temps où s’effectuent de très nombreux nivellements municipaux, complémentaires des premiers et souvent liés à des travaux d’adduction d’eau ou d’assainissement (construction ou amélioration d’égouts). J’ai décidé de m’intéresser à celui de Saint Germain-en-Laye, commune de l’ouest parisien à l’histoire particulièrement riche, parce qu’il a donné lieu à la création de repères en fonte étonnamment esthétiques.

[Termes IGN] série temporelleRésumé : (auteur) Images from archival aerial photogrammetric surveys are a unique and relatively unexplored means to chronicle 3D land-cover changes over the past 100 years. They provide a relatively dense temporal sampling of the territories with very high spatial resolution. Such time series image analysis is a mandatory baseline for a large variety of long-term environmental monitoring studies. The current bottleneck for accurate comparison between epochs is their fine georeferencing step. No fully automatic method has been proposed yet and existing studies are rather limited in terms of area and number of dates. State-of-the art shows that the major challenge is the identification of ground references: cartographic coordinates and their position in the archival images. This task is manually performed, and extremely time-consuming. This paper proposes to use a photogrammetric approach, and states that the 3D information that can be computed is the key to full automation. Its original idea lies in a 2-step approach: (i) the computation of a coarse absolute image orientation; (ii) the use of the coarse Digital Surface Model (DSM) information for automatic absolute image orientation. It only relies on a recent orthoimage+DSM, used as master reference for all epochs. The coarse orthoimage, compared with such a reference, allows the identification of dense ground references and the coarse DSM provides their position in the archival images. Results on two areas and 5 dates show that this method is compatible with long and dense archival aerial image series. Satisfactory planimetric and altimetric accuracies are reported, with variations depending on the ground sampling distance of the images and the location of the Ground Control Points.

[Termes IGN] photothèqueRésumé : (auteur) [Introduction] L'Institut national de l'information géographique et forestière (IGN) est chargé, depuis sa création en 1940, de la conservation des prises de vues aériennes du territoire français. Le fonds constitué depuis les années 1920 représente une source d'information majeure sur les transformations du paysage et les aménagements survenus depuis cette époque. Afin de le mettre en valeur, l'IGN s'est engagé dès 2007 dans une vaste opération de numérisation et de mise en ligne sur Internet des clichés. Les travaux se sont déroulés sur environ dix ans et sont en cours d'achèvement. Après un retour sur le contenu et l'historique des fonds, cet article présente les travaux entrepris pour la numérisation et le référencement des documents, ainsi que les opérations d'aménagement réalisées pour assurer la préservation durable des archives photographiques de l'IGN.

[Termes IGN] traitement de données localiséesRésumé : (auteur) This report Is the final report of the EuroSDR-project “Preserving the Geographical Production Process”. In two one day workshops (spread over two days) and one postconference workshop at the first annual conference of the International Council on Archives (ICA, since 1948) we have investigated the problem of the fading away of knowledge on the geographical production process, identified initiatives in Europe that preserve crucial parts of the geographical production process and the need for further awareness raising and a European forum for further cooperation, as:
* we share a common history of the geographical production process (although not always happening at the same speed),
* different parts of that history are preserved throughout Europe,
* the awareness of the need to preserve the geographical production process – in order to understand our geographical products today and in the future – is not sufficient by many of the producers and could be improved by a forum,
* local preservation initiatives lack a European, collaborative, cross-domain (NMCAs, libraries, archives and museums) approach that could avoid multiplication of the same efforts (such as the design of a database) on institutional and country level, which is in many cases hampering the preservation process. This report describes the project, presents the conclusions and contains the main deliverables of the project, which are:
* Two workshop reports
* Raised awareness amongst others at the relevant umbrella organisations:
EuroGeographics, International Council on Archives (ICA) and the International Cartographic Association (ICA)
* International Council on Archives first Annual Conference post-conference workshop to grow awareness in the global, archival community of geographical information (the data itself, the preservation of its production process, and as instrument to open-up archival information)
* An overview of the scattered preservation initiatives related to National Mapping Agencies (NMAs) throughout Europe
* Books (“Cartography. Vision on the map” (2016) for Dutch speaking archivists, and a chapter on “Evolution in Knowledge and Technology” in a book about Historical Cartography (in prep.))
* Inherent to the project, new initiatives on the preservation of the geographical production process, including
- a cooperation between the University of Gent and the National Mapping Agency of Belgium that digitized and inventoried documentation and objects, and documented working processes by replaying and recording old working processes
- ongoing work on a standard to describe witnesses (items, objects, …) of the geographical production process by the Royal Military Academy of Belgium, UGent, and the NGI-Belgium with the aim to develop a standard that could suit international cooperation
- the inheritance by the UGent from Alan Wright of his extensive collection of survey instruments. This collection not only outlines the important innovations in the geodetic instruments after WWII, but is also a reflection of a remarkable life in service of science
- an exhibition (2017) titled “Pushing the Boundaries” on the Wright-Draper collection of geodetic instruments in the Science Museum of Gent University
- an overview of institutions, societies, people, and their ‘local’ initiatives, as a starting point for collaboration
- a refined and reworked standard from the Royal Military Academy for the description of objects and documentation that could be potentially used as starting point for a European, collaborative database.
We are grateful to all participants of the workshops. The exchange of knowledge and
experiences has been a very valuable result to all of us, and could only be realized by the
dear support of EuroSDR. We would like to thank EuroSDR for the support. We are also
grateful for the support of EuroGeographics, the International Council on Archives and the
International Cartographic Association.Note de contenu : Introduction
