地学信息图谱的最新进展

地学信息图谱的研究已经从科学概念和定义、模式的研究,发展到对功能、作用等深层次问题的挖掘,以及向实际应用阶段迈进。本文首先介绍本研究组在地学信息图谱方向上的探索性研究总体思路,进而阐述相关领域的图谱对地学信息图谱研究的新启示意义,概述了我们在该方向上的理论研究成果,包括理论体系的建立、新的理论热点问题,并对地学信息图谱中的几个关键因子(尺度性因子、层次性因子、抽象度因子等)进行了透彻分析。在方法和技术进展部分,阐述了我们在地学信息图谱的自动/半自动归纳和提炼方法和技术方面的最新成果,以及地学信息图谱参数设计、地学基本单元的三维表达与虚拟重组等方法和技术。在此基础上,介绍了我们开发的地学信息图谱基础平台的设计和开发成果。最后,对黄土高原地貌形态信息图谱、中国多尺度水系网络信息图谱、中国综合自然景观信息图谱等实例进行了深入地分析。

The latest development on Geo-Info-TUPU

The research on GeoinfoTUPU is now towards deepgoing problems such as its compound functions, effects, as well as practical applications, other than merely on its scientific concept, definition and mode.This paper introduced, at first, our overall plans on GeoinfoTUPU, an explorative scientific subject, and then related new enlightenment from TUPU in relevant realm to GeoInfoTUPU. Secondly, the paper summarized the author's theoretic achievement in the subject, including the builtup of its theoretic system, the research on some new focus problems, and especially analyzed three key factors of GeoInfoTUPU, i.e., the dimension factor, hierarchy factor, abstractiondegree factor. Furthermore, the paper expounded the author's latest development on methods and technologies of GeoInfoTUPU, including the automatic or semiautomatic induction and extraction of, the parameter designing in, GeoInfoTUPU, and also the 3D display & virtual recomposition of geoobjects, etc. Based on the methods and technologies mentioned above, the design and development of the basic platform of GeoInfoTUPU was described. Finally, the paper analyzed three GeoInfoTUPU samples, i.e., the Demographic InfoTUPU of Lotus Plateau, the Hydrology Network InfoTUPU of China, and the Comprehensive Landscape InfoTUPU of China.
