[Termes IGN] SicileRésumé : (Auteur) Comparing images in the visible bands with maps from Istituto Geografico Militare Italiano, it was possible to localise many changes in the shape of the coastline of southern Sicily, Italy, from Porto Empedocle to Capo Passero, on the Italian side of the Malta Channel due to erosion and deposits. It was possible, also, to understand the effects of shore protection structures on coastline changes and on the ports development from a large scale point-of-view. Since behind the study area, along the coast, the land is very sensitive to rain erosion, significant images were selected, among many others, showing the effects of meteorological events on the sea. In particular, images showing the effects of rivers silt flooding along the coast were processed, in order to obtain information on the changes of the distribution in the above mentioned parameters in the sea water. From the analysis of these images, much useful information on the coastal areas sensitive to deposit and erosion was acquired.

[Termes IGN] température de l'airRésumé : (Auteur) The conversion of Digital Counts (DC) to surface temperature, for Thermal Infrared wavelenghts in TIROS-NOAA satellites, requires three steps: 1) calibration; 2) conversion of radiance to true temperature; 3) soil temperature after atmospheric and emissivity correction. The transformation of DC to radiance of the scene depends on the blackbody internal temperature and the representative cold space view sensed with the platinum resistance thermomethers. Header words 18, 19 and 20 each contain those measures and header words 23 to 52 provide ten internal target data each for Infra Red channels 3, 4 and 5. The conversion to brightness temperature from radiance is performed using the inverse of Planck's radiation equation. The non-linearity in the calibration is accounted for through the addition of a correction term to the brightness temperature of scene. From true brightness temperature, the split-window algorithm, determines the surface temperature. This methodology is applied to a group of images dated before, during and after a fire in Aznalcollar (Spain) for a temporal evolution analysis.

[Termes IGN] texture d'imageRésumé : (Auteur) This paper describes an approach to textural classification of remote sensing images. This study concerns the potential use of high spatial resolution textural features to identify different covers and discriminate between various surface types. These textural features are computed from grey-level cooccurrence matrix statistics at various pixel displacement distances. Textural classification is then performed using textural signatures. The approach is applied to a SPOT multispectral scanner data of the north of Algeria.

[Termes IGN] PologneRésumé : (Auteur) Grzedy reserve which belongs to The World Biosphere Reserve UNESCO and Biebrza National Park grow on the mineral “island" situated among wide-spread peat-swamps of the Biebrza river middle basin. The island is created by the tops of parabolic and oblong dunes, and forests growing there are under the little influence of anthropopression. Temporal sequence of panchromatic and colour aerial photographs presenting this natural phenomena, and real vegetation maps produced by ground exploration and traditional method of cartography have been used for analysis of riches of plant communities changes and their distribution from 1935 to 1997. Present and archival data about the vegetation give the opportunity to compare the amount of information about the forest landscape heterogeneity which has been achieved from the both sources.

[Termes IGN] surveillance météorologiqueRésumé : (Auteur) Spain is a country which is particularly affected by drought given that during the period from 1880 to 1980 over 50% of years were dry or very dry. During the 1990s the period from 1992 to 1995 was one of the driest in the century. In 1992 losses caused by drought in cereal crops were put at 50 655 million pesetas (47% of the total production value). In 1995 losses in crops were estimated at 27 971 million pesetas (30% of the total production value). The identification of areas affected by drought using information supplied by the AVHRR sensor on the NOAA satellites is viable if a sufficiently large data base is available and could prove useful for those in charge of monitoring this type of phenomena.
