Description:
Lack of accurate information on water distribution within an irrigation system is a major roadblock for effective management of scarce water resources. Numerical techniques to estimate canal water distribution require large amounts of data with respect to hydraulic parameters and operation of the hydraulic structures; such data are absent in large irrigation systems. In this study, six quantitative geomatic models, with varying complexity and physical representation, were formulated. They all use high-spatial resolution Landsat-7 images and a canal network stored in a GIS. The models require only the flow rates at the head of the distribution system to calculate downstream water distribution. Results were compared with discharge measurements for three tertiary canals (watercourses) within two selected secondary canals (distributaries), Gajiana and Ghour Dour, in Rechna Doab, Pakistan. The model that computed canal water distribution using the shape of the irrigated area was the most accurate at the watercourse scale. The overall deviation was 28% and the standard deviation of differences between modelled and measured flow was 10%. The model that relates canal water distribution directly to normalized difference vegetation index (NDVI) has the lowest accuracy with a 32% absolute deviation and 16% standard deviation. We conclude that geo-information techniques can be used to compute water distribution in large irrigation systems with a minimum of field data if an appropriate geomatic model is selected. ...

Description:
This paper presents a geomatics-based approach for the operational monitoring of spatio-temporal changes in a northern wetland. It demonstrates how valuable, and otherwise unattainable, spatially distributed and timely baseline data can be obtained using basic remote sensing techniques. It further shows how these data can be combined to retrieve information pertaining to the hydro-ecological relationships in the wetland. The study was conducted in the Peace-Athabasca Delta (PAD), which is a large wetland complex in northeastern Alberta, Canada. Combinations of Radarsat Synthetic Aperture Radar (SAR) and optical satellite images (Landsat or SPOT multispectral) were used to generate a time-series of flood maps for the six-year period, 1996 to 2001. These maps clearly depict the extent of the 1996 and 1997 overland floods and the subsequent water level draw down. A flood duration map that shows how long each image cell was inundated was generated by combining the series of flood maps. The flood duration map highlights regions where the duration of flooding appears to be highest or lowest. Such maps are invaluable for any ecological change detection protocols that may be developed for this region. The general vegetation patterns were also mapped using multi-temporal SPOT-4 images from the summer season (May and August) of 2001 to an accuracy of 86%. By comparing the vegetation and flood duration maps, the relationship between vegetation patterns and duration of flooding could be examined. Results indicated that basins inundated for longer periods (3-5 years) were dominated by relatively more productive graminoid (grass-like) vegetation, whereas, areas flooded for less than two years were characterised by less productive shrub vegetation. Airborne scanning LiDAR (Light Detection and Ranging) data from the summer (June) of 2000 were also used to generate a Digital Elevation Model (DEM) of selected non-flooded areas. LiDAR DEM accuracy was satisfactory (Root Mean Square Error of 0.24 m) and it proved to be sufficiently detailed to detect the subtle topographic patterns in this relatively flat region. Comparison of the vegetation map to the DEM demonstrated that the shrubs were located in areas that were, on average, between 0.5 m (in south) and 0.73 m (in north) higher than the graminoid covered regions. Notwithstanding other parameters that influence the distribution of vegetation, these results indicate that flood duration and elevation are two important factors. The usefulness of these spatial databases recommends the timely generation of flood and vegetation maps in the continued monitoring of the changes and relationships in this delta. ... Read more

Extrait : Netgraphe, compagnie québécoise fondée en 1996, était la plus importante entreprise d'édition francophone sur Internet au Canada à la fin des années 1990 et au début des années 2000. Le 30 septembre 1999, Netgraphe inc. est devenue la première entreprise Internet publique cotée à la Bourse de Montréal. Quebecor ayant pris le contrôle de la compagnie, toutes ses activités furent fusionnées avec celles du portail Internet Canoe.ca et le nom de Netgraphe fut abandonné en 2005. Ayant son siège social à Montréal, Netgraphe exerçait ses activités dans le secteur de l'édition sur Internet au Canada. La compagnie se spécialisait dans la diffusion de contenu, la publicité, le commerce électronique et les services de conception, de réalisation et de maintenance de sites Internet. À son apogée, elle exploitait, entre autres, les sites populaires suivants : Œuvrant dans la presse écrite, Yves Williams et Chrystian Guy créent le site La toile du Québec en mars 1995. Un passe-temps au début, le site prendra rapidement de plus en plus d'expansion autant en termes de nombre de sites recensés qu'en nombre de visiteurs. Le succès du site pousse les deux créateurs à quitter leur emploi et à s'associer à la compagnie de gestion Pluricom (détenue par Normand Drolet et Marc Copti) pour fonder la compagnie Netgraphe inc. en mai 1996. Bien vite, la compagnie commence à offrir des services de création de site Web. Les années suivantes vont voir la création par Netgraphe de plusieurs sites spécialisés : Comptoir, répertoire de sites québécois faisant du commerce électronique; Mégagiciel, un répertoire de jeux et de logiciels gr...http://booksllc.net/?l=fr ...

Description:
This paper addresses workflow issues of a Geomatics division in the Canadian Forces. This division is dedicated to the production of Geomatics Information under the US National Geospatial-Intelligence Agency's Foundation Based Operations concept. This paper outlines a methodology for modeling and analyzing the workflow of the Canadian Forces Geomatics division. A discrete event simulation model is developed and applied to measure the performance of the workflow system for developing Geomatics products. A hybrid queueing network/optimization model is also developed to support the simulation model. The objective of the queueing network/optimization formulation is to provide the optimal configuration of the Geomatics division. The paper successfully addresses a complex workflow problem in the context of real world system and provides insights into the performance of the Canadian Forces Geomatics processing. ... Read more

Description:
A GIS-based model for the prediction of road surface temperature is presented that has the ability to explain up to 74% of the spatial variation in road surface temperature in the West Midlands, UK. The approach combines basic spatial data sets with a synergy of surveying techniques to produce a geographical parameter database that drives the spatial component of a road weather prediction model. By measuring and modelling geographical parameters such as altitude, landuse, road construction and the sky-view factor, pre-existing components of road ice prediction systems can be united to provide a dynamic road ice prediction system. ion system. ...
