[Termes IGN] système d'information géographiqueRésumé : (Auteur) Understanding the spatial dimension of fear of crime in the urban environment is important to understanding behaviors in response to this concern. Making this connection between perception and action has long been a goal of scholars in the social and health sciences, though this complex relationship has yet to be fully elucidated. Specifically, in studies on fear of crime and its influence on behavior, a variety of definitions and methods have been employed. This situation has yielded insights, as well as inconsistencies. In the past decade, Geographic Information Systems (GIS) has been added to this methodological mix, though it too has contributed limited understanding of the environmental perception-behavior nexus. During this time, some scholars have integrated a traditional technique for accessing environmental perception, the sketch map, with this newer technology. This article provides a review and critical assessment of the way GIS has been used to understand fear of crime, specifically through the integration of sketch maps. This focus is framed by an overview of substantive and methodological concerns and concludes with a discussion of continued research needs. As behavioral responses to fear of crime are acknowledged to impact physical and mental health and overall well-being, in addition to the viability of neighborhoods, research in this area will continue apace. However, for integration of sketch maps in GIS to be a valuable methodological contributor to this line of inquiry, users of the approach must understand its complexities. This article outlines these issues so that they may be considered in future research and may improve the ability for this approach to yield new understanding of fear of crime.

[Termes IGN] voxelRésumé : (Auteur) Estimates of solar radiation distribution in urban areas are often limited by the complexity of urban environments. These limitations arise from spatial structures such as buildings and trees that affect spatial and temporal distributions of solar fluxes over urban surfaces. The traditional solar radiation models implemented in GIS can address this problem only partially. They can be adequately used only for 2-D surfaces such as terrain and rooftops. However, vertical surfaces, such as facades, require a 3-D approach. This study presents a new 3-D solar radiation model for urban areas represented by 3-D city models. The v.sun module implemented in GRASS GIS is based on the existing solar radiation methodology used in the topographic r.sun model with a new capability to process 3-D vector data representing complex urban environments. The calculation procedure is based on the combined vector-voxel approach segmenting the 3-D vector objects to smaller polygon elements according to a voxel data structure of the volume region. The shadowing effects of surrounding objects are considered using a unique shadowing algorithm. The proposed model has been applied to the sample urban area with results showing strong spatial and temporal variations of solar radiation flows over complex urban surfaces.

However, most studies have used them separately instead of in combination for land surface mapping. Considering their highly complementary nature, it is critical to investigate whether and how the integration of both can improve the accuracy of land cover and land use (LCLU) mapping. This study explored the use of Quickbird imagery and airborne Lidar data for mapping a complex urban environment in the City of Curitiba, Parana State, Southern Brazil, which is composed of secondary shrub vegetation, grass and climax primary Araucaria forests combined with urban objects such as roads and buildings. Airborne Lidar data were processed to generate DEM, DSM (Digital Surface Model), and DHM (Digital Height Model). The DSM generated from Lidar data were used to orthorectify Quickbird image with photogrammetric skills. A large number of metrics are generated from Lidar DHM, Lidar point cloud, Lidar intensity, and Quickbird imagery using object oriented segmentation approaches. Due to their power in handling non-parametric data, decision-tree based approaches were chosen to select the most relevant metrics and build rules for classification. It was found that the fusion of both types of data with decision trees increased the accuracy by 5 to 15% and resulted in an overall accuracy over 90%. Taking into account the increasing accessibility of Quickbird and airborne Lidar data, it is expected the methodology developed in this study has profound impacts in shifting our current paradigm in LCLU mapping.

[Termes IGN] zone urbaineRésumé : (Auteur) Persistent Scatterer Interferometry (PSI) is a technique to simultaneously estimate surface deformation and 3D structure from stacks of SAR images. It was proposed first about one decade ago to monitor preferably urban areas, where in general the highest numbers of PS are found. At that time no high-resolution satellite SAR data were available. Instead, for example, stacks of ERS imagery were used providing ground range resolution of about 25 m. In data of such kind only the strongest PS can be detected, which are usually caused by corner reflectors built by orthogonal building and road planes of considerable size, whereas smaller structures causing weaker ones signal are averaged by clutter or mutually interfere with others in the same resolution cell. Thus, if any, only a few or even just one single PS are found per building. The advent of a new sensor generation of systems like TerraSAR-X and COSMO-Skymed in 2007 led to a significant improvement of spatial resolution of about one order of magnitude. This comes along with a dramatic rise of PS density: In some cases tens to hundreds are detected at large buildings, which offers the possibility to monitor even individual urban objects. In addition, especially at building façades the distribution of those PS is often quite regular. A reason for that is the usually rectilinear arrangement of façade structures inducing PS like windows or balconies. Those patterns contain a lot of information about the objects under investigation, which is mostly ignored in current PSI processing schemes. For example, consider a regular structure of windows on a certain façade of a multi-story building. Assuming the same kind of structure generates one single PS at each window, the phase centers of all scatterers caused by windows of each floor share the same height. This means, we may benefit from such kind of redundancy, for instance, to improve the height estimate by averaging over PS having the same elevation. In this work, we first discuss the regular appearance of PS at urban façades for an urban test scene in TerraSAR-X spotlight mode data. Then, we show how PS analysis could benefit by exploitation of the redundancy due to repetitive patterns of man-made objects. Finally, we propose a PS grouping scheme based on a production system and discuss first results achieved for the test area.
