Advanced Techniques for the Representation and Use of Geographic Information

该奖项通过国家科学基金会的女科学家和工程师教师奖项目为Donna Peuquet博士提供支持。该项目的目标是表彰全国最杰出和最有前途的从事研究和教学相结合的学术职位的女科学家和工程师，将她们留在学术界，并促进她们职业生涯的进一步发展。该奖项将允许Peuquet博士继续研究地理信息的概念和物理表示方式，即基于计算机的数据观测。这项研究将建立在研究者已经进行的研究的基础上，该研究为地理信息系统（gis）中物理空间的表示建立了一个概念框架。还开发了软件，允许综合地理信息系统中基于位置和基于对象的数据表示。研究人员的下一个研究方向将包括扩展表征框架，使其包括时间维度，从而增强gis协助分析地理过程的时空维度的能力。研究者还将开始定义一种描述时空过程的正式空间语言，同时仍然结合上下文依赖关系和这些过程通常具有的不精确属性。这种形式语言应该提供比使用基于标准查询语言的方法更健壮和灵活的空间数据库查询语言。

This award provides support for Dr. Donna Peuquet through the National Science Foundation's Faculty Awards for Women Scientists and Engineers Program. The objectives of this program are to recognize some of the nation's most outstanding and promising women scientists and engineers holding academic positions combining research and teaching, to retain them in academia, and to facilitate the further development of their careers. This award will allow Dr. Peuquet to continue her research on the ways that geographic information is represented, both conceptually and physically, as computer-based data observations. This research will build on research already conducted by the investigator that establishes a conceptual framework for the representation of physical space in geographic information systems (GISs). Software also has been developed to permit synthesis of location-based and object-based representations of data in GISs. The investigator's next lines of inquiry will include expansion of the representational framework to include a temporal dimension, thereby enhancing the capabilities of GISs to assist in analysis of the spatial-temporal dimensions of geographic processes. The investigator also will begin to define a formal spatial language that describes spatial-temporal processes while still incorporating the context dependencies and inexact properties that often are characteristic of these processes. Such a formal language should provide a more robust and flexible spatial database query language than is available using standard query language-based approaches.
