[Termes IGN] trame verte et bleueMots-clés libres : renard Résumé : (auteur) Analysing landscape changes and their effects requires retrospective studies that have been carried out in the past but cannot be repeated in the future. Planning authorities need to be able to assess the impact of their decisions on the current landscape. In France, the political measure called Trame verte et bleue incites the authorities to take into account the effects of planning on biodiversity1. Landscape ecology and modelling contribute to these objectives. We have tested a simulation method for fauna movements at a local spatial scale.
This abstract is about one of our studied cases i.e. the effect of spatial planning in a peri-urban area on movements of red fox that is a generalist species with a large dispersion capacity. The tested developments are: a) the construction of a highway b) the construction of a highway with wildlife crossings c) the construction of a highway with wildlife crossings connected to an ecological corridor. Movement data were provided by E. Robardet5 and mapped in a GIS with RGE® geographical data. We determined the features of the landscape around the trajectories based on GPS points. Then we integrated the knowledge on the landscape characterisation in an agent-based model. Movement simulation was made for one agent i.e. one fox, with regard to its behaviour and the elements that can favour or hinder movementsa.
The constructed highway limits the total distance covered, from 6.9 km to 6.5 km per day on average (crossing probability set at 10 %b). The animal movement decreased, illustrating a barrier effect: we used as an index the number of the simulated localizations on the same side of the road divided by the total number of localizations. In the initial space, the index was equal to 0.42, due to the spatial distribution of the animal’s areas of interest. The index increased to 0.55 with the highwayc. When the road benefited from wildlife crossing structures, the results were quite the same. In the third scenario, the ecological corridor alleviated the barrier effect: the index remained around 0.41. Simulation shows that the distance covered decreased less from 6.9 km to 6.8 km.
Agent-based models are often used for modelling the interaction between species and space3 as well as human-animal conflicts2. We use it to model the influence that landscape elements have on fauna movements at a fine spatial scale. This method allows for considering the effect of the road as being separate from its spatial environment6, contrary to the cost path methods that aggregate land use which can be better adapted to habitat studies4. Our results reveal that the protection of landscape quality through ecological corridors seems quite effective to preserve movement capacity of species like fox. Simulations launched for deers allows for assessing the effects of roads in a forest area. On the basis of all the results, we propose a general model for considering planning effects, which can be a helping tool for planning.Numéro de notice : C2013-023 Affiliation des auteurs : LASTIG COGIT+Ext (2012-2019) Thématique : BIODIVERSITE/GEOMATIQUE Nature : Communication nature-HAL : Poster-avec-CL DOI : sans En ligne : http://www.iale2013.eu/assessing-effect-landscape-change-fauna-agent-based-model [...] Format de la ressource électronique : URL resumé Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=80091 Analyse des relations entre données géographiques et données localisées de faune / Laurence Jolivet (2012)

[Termes IGN] paysageRésumé : (auteur) Les modifications du paysage peuvent favoriser ou limiter les déplacements de la faune sauvage selon leur nature et également selon les comportements propres aux espèces. Un enjeu important est de connaître l’influence des éléments du paysage sur les déplacements afin de mieux appréhender l’impact de nouveaux aménagements. L’objectif est de déterminer quelles sont les données de description de l’espace permettant la recherche de corrélations, potentiellement liens de causalité, entre les éléments du paysage et les déplacements de faune. Nous souhaitons à partir des données spatiales et de localisations de faune existantes caractériser les éléments du paysage représentant des obstacles ou des zones favorables aux déplacements. La méthode proposée repose sur la recherche de relations entre des données géographiques et des localisations enregistrées d’animaux sur plusieurs zones et sur plusieurs espèces. Cette approche comparative a pour but d’évaluer d’une part les caractéristiques de déplacement selon les espèces et d’autre part les besoins particuliers en données géographiques selon les zones d’étude.

[Termes IGN] paysageRésumé : [introduction] Fauna movements depend on landscape features. They are led by the needs, depending on the species, for food, rest and breeding. The space animals live in is not only a habitat but also contains their hunting grounds (Ethier and Fahrig 2011), hideouts, obstacles and corridors of free movements (McGregor et al. 2008). Spatial changes due to the construction of infrastructures or to climate change (Jewett et al. 2011) require that individuals and populations adapt or migrate to other destinations. Our main objective is to identify spatial features impacting fauna movements. The space may be described by its components (vegetation, roads, topography...) which are liable to be qualified differently. In particular, spatial components have specific influence on fauna movements. We focus on how to construe the function these components have on movements depending on the species. Some may favour movements and on the contrary others limit or hinder animals from moving.

[Termes IGN] migration animaleRésumé : (auteur) The presented work focuses on the analysis of the relations between topographic features and animals movement in a context of biodiversity concern. Indeed space fragmentation is linked to loss of habitats and one proposal to favour displacements lies in maintaining and restoring ecological continuities. Our objective is to define a spatiotemporal model so that to highlight how land settlements and field shape influence movements. Our approach consists in modelling movements by taking into account animal specific behaviour and the spatial environment. Studies of land use by fauna enable new reading of the space and more particularly determination of species functional space organised in places dedicated to activities like feeding, resting, breeding and moving. From one species to another, environment apprehension differs and the challenge is to characterize the meaningful features in a multiple reading space. For instance, obstacles are not defined the same for roe deer as for wild boar. In order to reach this goal, we follow two methods. One is to analyse animal tracks on accurate fields. The second lies in the simulation of trajectories on real landscapes according to species. If these trajectories are relevant, we are to test spatial changes, like a corridor creation, and study its impact on movement.

[Termes IGN] Styled Layer DescriptorRésumé : (auteur) [introduction] Standard APIs to visualise geodata on information infrastructures, like OGC MapContext (OGC 2005) or StyledLayer Document (OGC 2007), focus on specifying the map spatial extent, size and styled layers. The selection of styled layers mostly relies on portrayed features and on the layer acceptable resolutions. Theoretically, the selection of a styled layer could in a near future also rely on the nature of portrayed features based on semantic annotations of feature types in catalogues. But more criteria need to be considered when designing a map, e.g. what relationships between features should be visually rendered or what will be the ambient light. More generally, cartographers point out the relevance of relying on a map requirements to design more usable maps which include usable styles (Forrest 1999) (Chesneau et al. 2005) (Nivala et al. 2007) (Jakobsson 2002) (Stanek et al. 2007)(Bucher et al. 2007). There are two distinct issues addressed in this paper. First issue is that defining fixed styles, e.g. for each INSPIRE layer, that will be used on any map is a very challenging task –if not impossible-. Yet, on the fly definition of adapted styles and feature portrayal is a costly process. A compromise is to define a registry of different styles for the same layers in order to adapt to different ‘criteria’ regarding the final map. Second issue is that many new map makers usually have no academic background in cartography (Gartner and Peterson 2007). They may not always be capable of retrieving relevant styled layers for their map in a registry based on the existing styled layers description (feature types and styling rules); they need an abstract querying model. This also holds when the map maker uses a graphical client to build his map from existing layers flows. In this paper, we introduce both an abstract map specification model and a registry of predefined styled layers, focused on the adequate usage of colours in topographic maps. We illustrate the relevance of the different elements of our model based on three sources. The first one is the French Geoportail experience. The second one is the usability study performed by (Nivala et al. 2007). They have evaluated the usability of Web maps based on end user tests and on expert assessments. The third source is a study where we have extrapolated large scale topographic maps keys from 15 European countries to the French BDTOPO® data model and applied the adapted keys to the same set of BDTOPO® data.
