Development of the system of spatial data management, sharing, and communication

在本项目的最后一期中，我们完成了系统的开发，并在演示文稿和论文中总结了研究成果。1)空间数据处理工具的开发我们开发了空间数据处理工具，包括面内插、数据格式转换等。它们是用Visual Basic编写的，因此可以直接与ArcGIS 8.1一起使用作为扩展。2)空间分析工具的开发我们已经开发了用于网络空间分析和二维平面时空分析的工具。3)空间数据共享系统的改进我们改进了空间数据共享系统，重点改进了空间数据共享系统的用户界面。目前已实现空间数据格式的自动转换、数据介质的选择和归档格式的选择，并在系统的开发过程中进行了口头演示和发表期刊论文来传播我们的研究成果。我们组织了几次关于该项目的研讨会和座谈会，并讨论了所取得的研究成果和未来需要挑战的主题。

In the last term of this project, we have finished the development of the system and summarize the products of research in presentations and papers.1)Development of tools for spatial data handling We have developed tools for spatial data handling including areal interpolation, data format conversion, and so forth. They are written in Visual BASIC so that they work directly with ArcGIS 8.1 as an extension.2)Development of tools for spatial analysis We have developed tools for spatial analysis on a network and spatiotemporal analysis on a two-dimensional plane. They are also written in Visual BASIC so that they work directly with ArcGIS 8.1 as an extension.3)Improvement of the system for spatial data sharing We have improved the system for spatial data sharing with a focus on the user interface. Automatic change of spatial data format, choice of data medium, and choice of archive format are available at present.As well as the development of the system, we gave oral presentations and published journal papers to disseminate the products of our research. We organized several workshops and symposia on the project and discussed the research products obtained and themes to be challenged in future.
