[Termes IGN] risque naturelRésumé : (auteur) In this study, we analyze 25 RADARSAT-2 images from ascending and descending geometries to study the creep rate on the Hayward fault and landslide motions near Berkeley, CA. We applied a coherence optimization technique from polarimetric synthetic aperture radar interferometry (PolInSAR) to increase the accuracy of the measurements. We resolve 3–5 mm/year of motion along the Hayward fault, in agreement with earlier creep estimates. We identify a potential motion on secondary fault, northeast and parallel to the Hayward fault, which is creeping at a lower rate of ~1.5 mm/year. In addition, we identify a number of landslides along the hills east of the fault that agree with earlier results from advanced interferometric synthetic aperture radar (SAR) analysis and field investigations. We investigate four particular slope instabilities, one of which was marked as moderately active, and three as highly active, by earlier field investigations. The resolved along-hill slope displacement is estimated at ~23 mm/year. Our results demonstrate that PolInSAR is an effective method to increase the interferometric coherence and provide improved resolution of deformation features associated with natural hazards.

[Termes IGN] végétationRésumé : (auteur) Annual disturbance maps are produced by the LANDFIRE program across the conterminous United States (CONUS). Existing LANDFIRE disturbance data from 1999 to 2010 are available and current efforts will produce disturbance data through 2012. A tiling and compositing approach was developed to produce bi-annual images optimized for change detection. A tiled grid of 10,000 × 10,000 30 m pixels was defined for CONUS and adjusted to consolidate smaller tiles along national borders, resulting in 98 non-overlapping tiles. Data from Landsat-5,-7, and -8 were reprojected to the tile extents, masked to remove clouds, shadows, water, and snow/ice, then composited using a cosine similarity approach. The resultant images were used in a change detection algorithm to determine areas of vegetation change. This approach enabled more efficient processing compared to using single Landsat scenes, by taking advantage of overlap between adjacent paths, and allowed an automated system to be developed for the entire process.

[Termes IGN] visualisation de donnéesRésumé : (Auteur) Recent advances in Web technologies have opened avenues to create socio-technical platforms that can empower citizens in urban planning processes. The rise of the GeoWeb and the popularity of Web 2.0 collaborative tools can facilitate the development of a new generation of bottom-up Public Participatory GIS (PPGIS) platforms that can incorporate user-generated content into Spatial Data Infrastructures (SDIs). New service-based delivery mechanisms can provide architectural flexibility and adaptability, and enable the public to benefit from ubiquitous information access. From an e-participation perspective, Web 2.0 social networking functions support interactive communication among various PPGIS stakeholders, e.g., citizens, planners, and decision makers. The main contribution of this article is to present a reference architecture for e-planning platforms that (1) facilitates effective e-participation by allowing multidirectional map-based communication among various land development stakeholders (e.g., planners, decision makers, citizens, etc.), and (2) enables incorporation of visualization, evaluation, and discussion capabilities to support community planning processes. To achieve this, we developed a service-oriented architecture (SOA) that exploits SDI principles and Web 2.0 technologies. The platform architecture allows heterogeneous data sources, analytical functionality and tools, and presentation frameworks to be plugged into a coherent system to provide a planning and decision support platform. We present two real-world implementations of the proposed architecture that have been developed to support community engagement in the City of Calgary, Canada.

[Termes IGN] web mappingRésumé : (auteur) Here we present Tambopata: Who Owns Paradise?, a map-centric, multimedia website created to enrich an educational role playing exercise about biodiversity, conservation, and development in the Amazon (www.geography.wisc.edu/tambopata). The exercise assigns students a character from the Tambopata region of the Peruvian Amazon, and asks them to evaluate four proposed zoning plans from their assigned perspective. Using principles of web cartography, we designed the four proposal maps to communicate complex information and allow for increased exploration. Compared to the previously used static maps, the website increases opportunities for student engagement with the material, incorporates multimedia, and clarifies spatial relationships and land use patterns. The website is available publicly and can be integrated freely into other university and high school courses.
