This program aims at the development of new methods and tools to improve GIS capabilities for more realistic modeling, representation, geovisualisation and analysis of complex geographic and social dynamics. Here, by dynamics, we refer to the changes through time. Global warming, global outbreak of H1N1 Swine Flu, urban growth, and human behaviour are examples of geographic dynamics. A realistic modeling and representation of such changes is necessary for better characterising, understanding, analysing and predicting of the behaviour of those phenomena at all local, regional and global levels. Current GIS through their powerful capabilities to process spatial data provides modelers with strong computing platforms for data management, integration, visualization, querying, and analysis. However, GIS are prone to problems when it comes to effective representation and visualisation of the geographic dynamics and have been criticized for not providing the necessary functionalities for analysing and predicting the behaviour of such phenomena. Geographic dynamics are usually multidimensional and change over time and space and their understanding needs multi-scale and multi-resolution representation, analysis, geovisualisation and management tools. These types of representations are particularly interesting in the context of decisional spatial databases which can facilitate the exploration and analysis of complex geographic dynamics for the users and decision-makers. Hence, the objective of this research program is to revisit and expand the fundamental concepts related to the representation, analysis and geovisualisation of geographic dynamics and their uncertainty and to develop new methods and tools to enhance GIS capabilities in this regard. To achieve this objective, we will use techniques in computational geometry, computer sciences,virtual and augmented reality and the geosimulation methods linked with advanced spatial on-line analytic processing technologies in spatial databases. These methods offer interesting opportunities for multidimensional representation, geovisualisation and analysis of geographic dynamics as well as their uncertainties that will be explored in this reserach programe.

该计划旨在开发新的方法和工具，以提高GIS的能力，更逼真的建模，表示，地理可视化和复杂的地理和社会动态分析。在这里，动态，我们指的是随着时间的变化。全球变暖、H1N1猪流感的全球爆发、城市增长和人类行为都是地理动态的例子。为了更好地描述、理解、分析和预测这些现象在地方、区域和全球各级的行为，有必要对这些变化进行切合实际的建模和表述。当前GIS通过其强大的空间数据处理能力，为建模者提供了强大的数据管理、集成、可视化、查询和分析的计算平台。然而，地理信息系统是容易出现的问题，当涉及到有效的表示和可视化的地理动态，并已被批评为不提供必要的功能，分析和预测的行为，这种现象。地理动态通常是多维的，并随着时间和空间的变化而变化，其理解需要多尺度和多分辨率的表示，分析，地理可视化和管理工具。这些类型的表示在决策空间数据库的背景下，可以方便用户和决策者探索和分析复杂的地理动态是特别有趣的。因此，该研究计划的目标是重新审视和扩展有关的表示，分析和地理动态及其不确定性的地理可视化的基本概念，并开发新的方法和工具，以提高GIS在这方面的能力。为了实现这一目标，我们将使用计算几何，计算机科学，虚拟现实和增强现实技术以及与空间数据库中先进的空间在线分析处理技术相关联的地理模拟方法。这些方法提供了有趣的机会，多维表示，地理可视化和地理动态分析，以及他们的不确定性，将在本研究中探讨。
