This POWRE project will provide the resources needed to study representations of dynamic geographic processes and methods of geospatial knowledge discovery about patterns and behaviors of these processes in Geographic Information Systems (GIS). The study will address three key research questions: (1) What kinds of information are useful to understand geographic processes? (2) How should geographic processes be represented so that needed information can be computed from GIS databases? and (3) How can exploratory and analytical tools be designed with the proposed geographic representation to facilitate knowledge discovery in GIS?Research on representation for dynamic geographic processes is urgently needed and can have a significant impact on methodologies for all sciences that use geospatial data to understand the dynamics of physical and human systems. As GIS development gradually merges into mainstream information technology (IT), innovative GIS research that emphasizes the computational fundamentals of geographic information representation and analysis requires advanced knowledge and skills in a melange of GIS, IT, and a chosen application domain. To meet such a multidisciplinary challenge, the POWRE study will start a new line of research that applies data mining and knowledge discovery methods in GIS to unveil spatial patterns of weather behaviors from meteorological and climatological data. The research framework to be developed in the study will be readily applicable to GIS knowledge discovery in other application domains.The POWRE award will give the PI, recently granted academic tenure, a unique opportunity to develop a major research program in geographic representation and knowledge discovery in GIS at this juncture in her career. This ultimately will contribute to a greater integration of GIS and IT technologies to enhance the usefulness of volumetric scientific data that are costly acquired at a phenomenal rate.

该POWRE项目将提供研究动态地理过程的表示以及地理信息系统（GIS）中这些过程的模式和行为的地理空间知识发现方法所需的资源。该研究将解决三个关键研究问题：（1）哪些类型的信息有助于理解地理过程？ (2) 应如何表示地理过程，以便可以从 GIS 数据库计算所需的信息？ (3) 如何利用拟议的地理表示来设计探索和分析工具，以促进 GIS 中的知识发现？迫切需要对动态地理过程的表示进行研究，并且可能对使用地理空间数据来进行研究的所有科学方法产生重大影响。了解物理和人类系统的动力学。随着 GIS 发展逐渐融入主流信息技术 (IT)，强调地理信息表示和分析的计算基础的创新 GIS 研究需要 GIS、IT 和所选应用领域相结合的先进知识和技能。为了应对这样的多学科挑战，POWRE 研究将启动一个新的研究领域，应用 GIS 中的数据挖掘和知识发现方法，从气象和气候数据中揭示天气行为的空间模式。该研究中开发的研究框架将很容易适用于其他应用领域的 GIS 知识发现。POWRE 奖将为最近获得学术终身职位的 PI 提供独特的机会，以开发地理表征和知识发现方面的主要研究项目在她职业生涯的这个阶段，她从事 GIS 工作。这最终将有助于 GIS 和 IT 技术的更大程度的整合，以提高以惊人的速度获取的成本高昂的体积科学数据的有用性。
