[Termes IGN] zone semi-arideRésumé : (Auteur) In this study, we have implemented a fast atmospheric correction algorithm to IRS-P6 advanced wide field sensor (AWiFS) satellite data for retrieving surface reflectance under different atmospheric and surface conditions. The algorithm is based on MODIS climatology products and simplified use of Second Simulation of Satellite Signal in Solar Spectrum (6S) radiative transfer code. The algorithm requires information on aerosol optical depth (AOD) for correcting the satellite dataset. The atmospheric correction algorithm has been tested for IRS-P6 AWiFS False colour composites covering the International Crops Research Institute for the Semi-Arid Tropics Farm, Patancheru, Hyderabad, India, under varying atmospheric conditions. Ground measurements of surface reflectance representing different land use/land cover, i.e. red soil, chick pea, groundnut and pigeon pea crops were conducted to validate the algorithm. Terra MODIS AOD550 validated with Microtops-II sun photometer-derived AOD500 over the urban region of Hyderabad exhibited very good correlation of ?0.92, suggesting possible use of satellite-derived AOD for atmospheric correction.

[Termes IGN] projection de Mercator obliqueRésumé : (Auteur) Precise geometric rectification of satellite imagery normally requires knowing the geodetic location of features identifiable in the image, called ground control points (GCPs). In many cases, however, it is difficult to compute a precise geometric rectification because too few GCPs are available due to the lack of ground data or the nature of the terrain (lakes or oceans, deserts, continuous forest, etc). When too few GCPs are available, Space Oblique Mercator (SOM) projection theory can be applied to provide continuous precise geometric rectification of image tiles or scenes. We use GCPs from adjacent, prior, or subsequent image tiles to create the projection geometry for the intermediate tiles. In this paper, we report on the development of a procedure to implement the use of ancillary GCPs in georectifying under-controlled imagery. To validate our method, a test example was computed using 1999 data obtained by a panchromatic camera on board the Indian Remote Sensing satellite IRS-1C with a spatial resolution of 5.8 m. The testing showed that the precision of geometric rectification in a tile without GCPs is within three pixels (about 17.4 m), and the speed of computation is faster than with traditional methods.

[Termes IGN] tectoniqueRésumé : (Auteur) The Netravati and Gurpur (N-G) river basins are tectonically active due to a number of seismically active faults/lineaments and their proximity to Mulki-Pulicat Lake axis. The gradient of the river channels has gradually reduced (after ?10 km from their origin) and has forced the rivers to flow slowly in meandering and zigzag paths. The nature and intensity of meanders are governed by geological and tectonic conditions of the river basins. Significant changes in river channels, between the years 1910 and 2005, have been detected in three blocks - Block-I (Netravati) and Blocks-II and III (Gurpur) - and studied in detail by comparing topographic maps with Indian Remote Sensing Satellite, LISS-III images through GIS techniques. The block-wise qualitative and quantitative changes of these channels indicate that they are narrowed and migrate towards south due to neotectonic activities, formation of braided islands, variation in flow intensity and anthropogenic interventions like construction of vented dams and sand mining.

[Termes IGN] traitement d'imageRésumé : (Auteur) In the present work multi-spatial, spectral and temporal images taken from space platform were acquired to analyze Talakadu (an archaeological site in Karnataka, India) area and identify linear features and geometrical shapes on the surface that are not natural but can be human artefacts from the past and therefore might indicate potential loca-tions for archaeological exploration. Before such remote sensing data can be used they have to be processed and prepared for facilitating meaningful interpretation. The scope and importance of image processing and enhancements depend on the sur-face conditions of study area. The peculiar geo-graphical configuration of the Talakadu area has made the greater part of an old township complete-ly buried under wind blown sand from the river Kaveri that skirts the west of Talakadu. Towards carrying out analysis in spatial, spectral and tem-poral domains, space imagery from Landsat Thematic Mapper, Multispectral images from LISS-IV sensor of Indian Remote Sensing Satellite (IRS) series and high resolution images from IRS CAR-TOSAT series were used. Several image-processing algorithms were employed to evaluate their effica-cy to identify linear features and geometrical shapes that might indicate presence of buried remains. These include enhancements and improve-ments in data quality, Pan sharpening, Principal Component Analysis for enhancement and change detection studies. These analyses were conducted after subjecting all the imagery to a common refer-ence frame through automated registration using non-linear methods with sub-pixel accuracy. This work presents the details of the various image pro-cessing techniques used to investigate their effica-cy in the context of identifying the different archae-ological details both known ones and possibly new potential locations. Our preliminary analysis indi-cates at least four likely locations for further archaeological exploration, thus suggesting a new approach in the light of the methodology available.

[Termes IGN] TurquieRésumé : (Auteur) In this study, the adverse effects of the Marmara earthquake of 17 August 1999 on the land use/land cover (LULC) of Kocaeli province in Turkey were analysed by integration of ERS-2, LANDSAT TM, SPOT-4 and IRS-1C data of varying spectral and spatial resolutions with ground data such as geological maps, soil maps and elevation data. The study was carried out in three main stages. The first stage consisted of studies on the deformation of the Earth's crust, damage in the urban texture and changes to the coastline through analysis of satellite data before and after the earthquake. Earth crust deformations resulting after the earthquake were mapped by synthetic aperture radar (SAR) data using a SAR interferometer. Damage in urban centres and coastline changes were assessed by analysis of SPOT and LANDSAT imageries. IRS data after the earthquake were used for the current LULC map of the entire province. The second stage involved settlement suitability analysis by multicriteria evaluation (MCE) methodology taking into account the geological formations, land cover, soil classes, slope, main transportation network, and urbanization status of Kocaeli province. In the third stage, the results obtained through the settlement suitability analysis were interpreted by the information generated through satellite imageries.
