[Termes IGN] température de surfaceRésumé : (Auteur) Multiple satellite sensors are used to analyze physical processes that determine energy fluxes and their interaction at the urban surface. The study is based on summertime microclimate analyses of the Los Angeles and Paris metropolises. The method consists of deriving some parameters governing the surface heat fluxes, constructing statistics of thermal infrared images, and using a GIS to combine them with a landcover classification from SPOTHRV multispectral images, and with data from intensive insitu experiments. The average images reveal spatial and temporal variations of land surface temperature (LST), and distinct microclimatic patterns. The combined interpretation of the statistics images and of the landcover classification shows: (i) the effect of surface physical properties, especially in downtown business and industrial districts that display heatislands larger than 7°C; (ii) the temperating influence of water; (iii) the negative correlation between afternoon land surface temperature and normalized vegetation index, which confirms the cooling effect of urban parks; (iv) the correlation between variations of surface temperature and ozone concentration at diurnal and longer time scales.

[Termes IGN] simulation dynamiqueRésumé : (Auteur) Sudden Oak Death is caused by a newly discovered virulent pathogen (Phytophthora ramorum) that is killing thousands of native oak trees in California. We present a landscape-scale study on the spatio-temporal dynamics of oak mortality. Second-order spatial point-pattern analysis techniques (Ripley's K) were applied to the distribution of dead tree crowns (derived from high-resolution imagery) in Marin County, California to determine the existence and scale of mortality clustering in two years (2000 and 2001). Both years showed clustering patterns between 100 and 300 m. A classification tree model was developed to predict spatial patterns of risk for oak mortality based on several landscapescale variables. Proximity to forest edge was the most important explanatory factor, followed by topographic moisture index, proximity to trails, abundance of Umbellularia californica, and potential summer solar radiation. This research demonstrates the utility of integrating remotely sensed imagery analysis with geographic information systems and spatial modeling for understanding the dynamics of exotic species invasions.

This shift has reduced the data collection time and begun to provide timelier information that engineers can use to better mitigate any deformation effects.

[Termes IGN] superposition d'imagesRésumé : (Auteur) The goal of this research was to explore the utility of very high spatial resolution, digital remotely sensed imagery for monitoring land-cover changes in habitat preserves within southern California coastal shrublands. Changes were assessed for Los Penasquitos Canyon Preserve, a large open space in San Diego County, over the 1996 to 1999 period for which imagery was available. Multispectral, digital camera imagery from two summer dates, three years apart, was acquired using the Airborne Data Acquisition and Registration (ADAR) digital-camera system. These very high resolution (VHR) image data (1 m), composed of three visible and one near-infrared wavebands (V/NIR), were the primary image input for assessing land cover change. Image-derived datasets generated from georeferenced and registered ADAR imagery included multitemporal overlays and multitemporal band differencing with threshold selection. Two different multitemporal image classifications were generated from these datasets and compared. Single-date imagery was analyzed interactively with image-derived datasets and with information from field observations in an effort to discern change types. A ground sampling survey conducted soon after the 1999 image acquisition provided concurrent ground reference data. Most changes occurring within the three-year interval were associated with transitional phenological states and differential precipitation effects on herbaceous cover. Variations in air temperatures and timing of rainfall contributed to differences that the seven-week image acquisition offset may have caused. Disturbance factors of mechanical clearing, erosion, potentially invasive plants, andfire were evident and their influence on the presence, absence, and type of vegetation cover were likely sources of change signals. The multitemporal VHR, V/NIR image data enabled relatively fine-scale land cover changes to be detected and identified. Band differencing followed by mutlitemporal classification provided an effective means for detecting vegetation increase or decrease. Detailed information on short term disturbance effects and long-term vegetation type conversions can be extracted if image acquisitions are carefully planned and geometric and radiometric processing steps are implemented.

[Termes IGN] nivellement par GPSRésumé : (Auteur) A GPS survey designed to precisely estimate ellipsoidal height was conducted in 1997 on benchmarks of a precise leveling line in Imperial Valley, California, a line actively leveled to monitor ground subsidence related to geothermal fluid withdrawal. The survey duplicated a 1995 survey. Data were analyzed to estimate differences in ellipsoidal height between adjacent benchmarks. GPSderived height differences for 1997 were compared to 1995 differences. Discrepancies were analyzed to identify leveling sections in which vertical movement might have occurred. Three such sections were identified.
