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

在这个项目的最后一个学期，我们完成了系统的开发，并在报告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，包括面插值、数据格式转换等。它们是用Visual BASIC编写的，因此它们可以作为扩展直接与ArcGIS 8.1一起工作。2)空间分析工具的开发我们开发了网络空间分析工具和二维平面时空分析工具。它们也是用Visual BASIC编写的，因此它们可以作为扩展直接与ArcGIS 8.1一起工作。(3)完善空间数据共享体系。以用户界面为重点，完善空间数据共享体系。目前可实现空间数据格式的自动更改、数据介质的选择、归档格式的选择。在开发系统的同时，我们还进行了口头报告和发表期刊论文，以传播我们的研究成果。我们组织了几次研讨会和专题讨论会，讨论了获得的研究成果和未来要挑战的主题。

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.
