[Termes IGN] système d'information géographiqueRésumé : (Auteur) Spatial optimization problems, such as route selection, usually involve multiple, conflicting objectives relevant to locations. An ideal approach to solving such multiobjective optimization problems (MOPs) is to find an evenly distributed set of Pareto-optimal alternatives, which is capable of representing the possible trade-off among different objectives. However, these MOPs are commonly solved by combining the multiple objectives into a parametric scalar objective, in the form of a weighted sum function. It has been found that this method fails to produce a set of well spread solutions by disregarding the concave part of the Pareto front. In order to overcome this ill-behaved nature, a novel adaptive approach has been proposed in this paper. This approach seeks to provide an unbiased approximation of the Pareto front by tuning the search direction in the objective space according to the largest unexplored region until a set of well-distributed solutions is reached. To validate the proposed methodology, a case study on multiobjective routing has been performed using the Singapore road network with the support of GIS. The experimental results confirm the effectiveness of the approach.

[Vedettes matières IGN] AltimétrieRésumé : (Auteur) Since the beginning of 2006, the vertical control system in Israel has been ellipsoidal. The Survey of Israel (SOI) will not continue with nationwide precise leveling. Instead, data from permanent Global Navigation Satellite Systems (GNSS) stations are used to develop and maintain Israel's ellipsoidal vertical control system. Currently, the objective is to provide a framework on which topographers and engineers can base and adjust their heights, and this is achieved more easily by GNSS measurements. Despite this, many users of height data prefer the orthometric system, even though its control is localized. A geoid undulation model is one of the foundations of the geodetic infrastructure. It is used to connect ellipsoidal and orthometric heights. Intensive utilization of GNSS for geodetic, surveying and engineering applications necessitates the development of an undulation model. Efforts to develop such a model with an accuracy level of 1 centimeter over an entire country demand multiple resources. This paper suggests a method for developing a national, orthometric control system with a reasonable accuracy, using GNSS measurements, ellipsoidal vertical control, and an official geoid undulation model. Research was conducted in Israel in order to test the feasibility of using an official geoid undulation model. Two kinds of official models were tested: the worldwide geopotential model (GPM98B) and a local, countrywide model computed by the Survey of Israel. We compared orthometric height differences obtained by GPS measurements with the known orthometric differences. This paper presents the results of those experiments. The technique proposed in this paper was found to define seamless orthometric vertical control adequate for most geodetic and surveying purposes, at low cost and fast. Of special interest in the paper is the comparison between the proposed idea and the National Geodetic Survey (NGS) attitude toward GPS-derived orthometric heights. The advantage of using the official geoid undulation model for the acquisition of orthometric heights is demonstrated.

[Termes IGN] utilisation du solRésumé : (Auteur) Rapid land development in rapidly growing countries has created a series of land-use problems. The implementation of sustainable land use can alleviate some of these problems. It needs a set of tools for the exploration, design, modification, illustration, and evaluation of alternative planning scenarios. This paper demonstrates that the integration of cellular automata and agent-based modelling can provide a spatial exploratory tool for generating alternative development patterns. Sustainable development strategies are embedded in the modelling to regulate agents' behaviours. The use of agents can help to represent human-environment interactions in solving complex land-use problems. It is able to examine the effects of different stakeholders in influencing the process of land development. The proposed model has been applied to the simulation of planning scenarios for residential development in a rapidly expanding city in the Pearl River Delta.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Geospatial technology is an essential component of the Environmental Impact Assessment (EIA) process, as environmental resources are directly affected by changes in the shape and extent of the proposed disturbance. With the use of spatial techniques like remote sensing, Geographical Information Systems, and Global Positioning Systems, EIA has enhanced substantial viewing, movement, query, and even map-making capabilities. However, one of the main challenges is to have access to the most up-to-date and accurate geospatial data and interpretations. With an emphasis on using geospatial data in particular, the value of the information resource is far higher than is generally available with text and numeric information. This paper focuses on discussing the application of geospatial tools in environmental monitoring and the effective analysis of the natural resources for developmental planning, policy formulation, and decision-making. Several specific relevant applications of geospatial tools to integrate EIA are presented in the context of an Indian scenario. Applications have included monitoring of natural resources (air, water, land, etc.), ground-level ozone, soil erosion, study of sea-level rise due to global warming, change-detection studies, delineation of ecologically sensitive areas using digital-image analysis and Geographic Information Systems. This study focuses on the possibility of using a proposed spatial-decision-support system to conduct EIA, which should make it possible to upload, evaluate, maintain, and report field and analytical data that have been stored in a variety of formats.
