[Termes IGN] Tsinghua (microsatellite)Résumé : (Auteur) By far the biggest source of the data needed for geospatial intelligence purposes comes from the high resolution imagery acquired from spaceborne and airborne platforms. In the specific context of South and East Asia, where there are numerous concerns about national security and threats from neighbours, the primary source for this type of intelligence is spaceborne imagery. Indeed the defence and security agencies in the larger countries in this part of Asia have all been large consumers of the high-resolution space imagery provided, by commercial suppliers such as GeoEye, DigitalGlobe, SPOT Image and ImageSat International. However, recently, nearly all of these Asian countries have either acquired or they are creating their own national capabilities to acquire this type of imagery to overcome the actual or potential restrictions and the delays that occur with the supply of space imagery from sources out with their control. The situation has already been discussed in a preliminary manner in an article published in Geolnformatics by the present writer three years ago (in the March 2004 issue) as part of his world wide survey of high-resolution imaging from space. This new article will concentrate on the many new developments that have taken place in the region since then.

[Vedettes matières IGN] CartologieRésumé : (Auteur) Depuis 10 ou 15 ans, on s'interroge à savoir si les SIG sont des outils objectifs neutres ou s'ils servent les intérêts de l'état ou d'autres sociétés. Malgré les discussions à ce sujet, aucun consensus n'a encore été atteint à ce sujet, ce qui a amené certains chercheurs à explorer d'autres manières de contextualiser le développement des SIG, leur emploi et la recherche connexe.; Daniel Sui et Michael Goodchild sont deux des chercheurs qui se sont penchés sur cette question. Selon eux, les SIG sont des médias et, par conséquent, peuvent être étudiés à la lumière de la théorie des médias de Marshall McLuhan. Leurs résultats sont convaincants à grande échelle. Dans le présent article, nous nous basons sur leur travail pour appliquer ce concept à deux études de cas à petite échelle: une en Inde et l'autre au Minneapolis. Les résultats de cette analyse appuient ceux de Sui et Goodchild. Ainsi, l'utilisation d'un SIG comme média (a) souligne l'importance croissante des SIG en tant que formes modernes de communication ou de média; (b) montre aux concepteurs de SIG, à leurs utilisateurs et à ses opposants que les décisions basées sur les SIG peuvent influer sur des gens précis à la fois positivement et négativement; et (c) rappelle à la société et à la communauté liée aux SIG que des effets inverses à ceux attendus possibles lorsqu'on adopte des SIG ou des technologies que leur sont associées sans se questionner.

[Termes IGN] transformation rapide de FourierRésumé : (Auteur) Fusion of optical and synthetic aperture radar data has been attempted in the present study for mapping of various lithologic units over a part of the Singhbhum Shear Zone (SSZ) and its surroundings. ERS-2 SAR data over the study area has been enhanced using Fast Fourier Transformation (FFT) based filtering approach, and also using Frost filtering technique. Both the enhanced SAR imagery have been then separately fused with histogram equalized IRS-1C LISS III image using Principal Component Analysis (PCA) technique. Later, Feature-oriented Principal Components Selection (FPCS) technique has been applied to generate False Color Composite (FCC) images, from which corresponding geological maps have been prepared. Finally, GIS techniques have been successfully used for change detection analysis in the lithological interpretation between the published geological map and the fusion based geological maps. In general, there is good agreement between these maps over a large portion of the study area. Based on the change detection studies, few areas could be identified which need attention for further detailed ground-based geological studies.

[Termes IGN] système expertRésumé : (Auteur) Reservoir management involves allocating available water among multiple uses and users, minimizing the risks of water shortages and flooding and optimizing the beneficial use of water. Irrigation demands from a reservoir, which are generally computed by using the design cropping pattern and average rainfall conditions, may vary over the years depending on the actual cropping pattern and meteorological conditions. This study demonstrates the utility of remote sensing inputs and geographic information system (GIS) environment for determining realistic irrigation demands from a reservoir. Remote sensing data are used to map the actual cropping pattern in the command area while the GIS is used for integrating the field-level irrigation demands up to the canal system head. Ten daily irrigation demands in the command area of Samrat Ashok Sagar Reservoir in Madhya Pradesh, India, have been estimated and the reservoir operation policy has been derived. Through the simulation analysis with 29 years of inflow data, rule curves have been derived for the operation of reservoir so that water deficit (if any) can be distributed in time much in advance and severe crop failure can be avoided. Inferences drawn from the analysis can guide the system operator in using the available water in a scientific and judicious manner.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Census is the count or inventory of specific phenomenon, such as population, wild life, industry, livestock etc. Another aspect is that census is carried out periodically to show the changing trends of the phenomenon and state. Space based imaging systems, from their vantage position, has unambiguously demonstrated their capability in providing vital information on natural resources. With the availability of high-resolution multi-spectral and panchromatic earth observation images and geographic information system, can we now consider a natural resources census? The census of natural resources - land, water, soils, forests and other elements conducted in a systematic manner and with a repeat cycle to depict changes and modifications can provide a "snap-shot" of a country's status of natural resource at a particular moment of time and help in identifying areas of rapid and significant changes, which can be monitored in detail. Such inventory with periodic monitoring would help in managing the natural resources and will provide inputs to meet the demands of large population in terms of more food production, more energy generation, water management, better civic amenities, more infrastructure built-up and increasing per-capital expenditure for maintaining a quality of life. In India, Natural Resources Census (NRC) programme has been conceptualized and is being implemented. The NRC will use Indian Remote Sensing satellite images and prepares natural resources information layers of 7 key themes (land use/land cover, soil, geomorphology, vegetation, snow/glacier, land degradation, wetlands) at 1:50,000 scale with the periodicity of 5-20 years for different themes. The NRC maps and data support the repository of natural resources information and contribute to the operationalisation of a spatial data infrastructure (SDI). Recognising that standardization of methodology for mapping and spatial database generation to enable NRC for SDI is important, few proto-type NRC studies has been conducted. This paper discusses the concept of a nation-wide NRC programme and the results of one of the proto-type studies (Bangalore urban district) that India has carried out. The concept, methodology and standards suggested for NRC will be certainly useful for any country.
