[Termes IGN] transfert radiatifRésumé : (Auteur) The present investigation evaluates surface reflectance retrieved from Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) and Compact Airborne Spectrographic Imager (casi) data using the atmospheric radiative transfer (RT) codes: atmospheric removal program (ATREM), Canadian advanced modified 5S (CAM5S) and moderate atmospheric radiance and transmittance model (MODTRAN4). The retrieved surface reflectances were compared with groundbased reflectances acquired with a GER3700-spectroradiometer for a playa and canola target. The results showed that the best overall performance was achieved with MODTRAN4 (average relative error of 2.3%), followed by ATREM (3.6%) and CAM5S (4.2%). Major differences occur in the stronger gas absorption regions. At wavelengths unaffected by strong gaseous absorption, the performance was similar for the three RT codes even though ATREM and CAM5S make extensive use of analytical expressions and, therefore, have faster execution times.

[Termes IGN] satellite d'observation de la TerreRésumé : (Auteur) In general, the U.K. is often regarded as having a rather low level of involvement when space remote sensing activities are being considered. This is indeed the case with certain of the fields being covered by Geoinformatics - wich often require the use of high-resolution imagery. However, over the last ten years, the U.K. has, in fact, become much more active in terms of conducting Earth Observation (EO) from space. Mostly this has been concerned with environnmental mapping and monitoring on a regional or global scale. Essentially the emphasis in the U.K. has been on the acquisition of imagery having a wide spatial coverage and rather coarse (large) ground pixel sizes, mostly for use by the environmental science community. Beside this activity, the U.K. has developped a leading position in the design, development, construction and operation of micro-and mini-satellites. This has attracted widespread attention, especilly from developing space nations wishing to acquire a national capabnility of Earth Observation (EO) from space. Copyright Geoinformatics.

[Termes IGN] méthode robusteRésumé : (Auteur) There are many factors to consider in carrying out a hyperspectral data classification. Perhaps chief among them are class training sample size, dimensionality, and distribution separability. The intent of this study is to design a classification procedure that is robust and maximally effective, but which provides the analyst with significant assists, thus simplifying the analyst's task. The result is a quadratic mixture classifier based on Mixed-LOOC2 regulized discriminant analysis and nonparametric weighted feature extraction. This procedure has the advantage of providing improved classification accuracy compared to typical previous methods but requires minimal need to consider the factor mentioned above. Experimental results demonstrating these properties are presented.

[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.

[Termes IGN] urbanisationRésumé : (Auteur) This study advocates the use of GIS and remote sensing technologies to establish urban evolution maps and assess the impact of urbanization on agricultural areas over the last three decades. The target area is the city of BeniMellal, located in central Morocco. The methodology adopted makes use of panchromatic SPOT images to survey the urban areas during the 1980s and 1990s. Available topographic maps provided the information for the 1970s. Maps and statistics of land use and urban growth for Beni Mellal were established after manually classifying images on a perpolygon basis and digitizing topographic maps using GIS capabilities. The results show an increase in dense urban area by 980.7 ha from the 1970s to the 1990s. This increase occurred at the expense of forests (24.7 ha), plantations (752.3 ha), rangeland (113.4 ha), nonirrigated land (69.7 ha), and irrigated land (20.6 ha). During this period, scattered urban areas, predominantly suburbs, increased by 755.9 ha to the detriment of forests (14.9 ha), plantations (109.8 ha), rangeland (138.9 ha), nonirrigated land (400.5 ha), and irrigated land (91.9 ha). These cartographic and statistic results are efficient decisionmaking tools for protecting agricultural land and planning urban and suburban areas.
