【摘要】 本文首先从异构空间数据共享相关理论研究着手,在对国内、国外关于异构空间数据共享理论、技术、方法研究的基础上,对GIS数据语义共享进行了详细地介绍。认为只有基于语义层次的异构空间数据共享才能使真正意义的空间信息共享得以实现。进而对基于语义异构空间数据转换模型进行了深入地研究,从模型的定义、原理、组织构成进行了详细地阐述。为了使模型研究满足于实际应用的需要,对模型物理实现的技术路线做了进一步的探讨。最后通过江苏省国土资源信息化示范项目——《国土资源空间/非空间数据一体化管理技术及信息化管理》的研究课题——江苏省国土资源异构空间数据模型研究及空间数据转换平台软件开发项目为例,对模型进一步的实际应用进行了实践。本论文研究的主要内容有: 1、对空间信息共享的几种方式进行比较,认为基于语义的空间数据共享是当前空间信息共享的主流方式。 2、GIS数据语义进行研究。明确地理信息共享得以实现的层次机构。 3、多源空间数据的研究。对当前主流GIS平台、辅助制图平台以及数据库管理信息系统的数据格式、逻辑组织方式进行了研究。 4、对基于语义异构空间数据转换模型进行研究,提出在空间数据转换时,各种空间数据模型之间的冲突可以通过语义信息的继承和扩展来解决和代替。 5、对模型实现的技术路线进行进一步的探讨。针对以模型为依托的空间数据转换引擎的结构进行设计以及应用设计。 6、江苏省国土资源异构空间数据转换平台的构建。在对江苏省国土部门的国土空间数据现有情况进行综合分析的基础上。采用加拿大Safe Software公司的FME提供的COM组件接口(FME objects)进行构件式开发,从而构建针对江苏省国土部门量体裁衣的新一代空间数据转换共享平台软件。 7、研究在平台建设过程中必然处理的诸如:数据逻辑模型映射、模型控制转换、语义控制转换(语义定制、数据风格处理)等

【Abstract】 This thesis is from the relevant theoretical research about the sharing of multi-source spatial data to set about at first. Through the study about multi-source spatial data share theory, technology and method, have introduced in detail to GIS data semantic share. Draw the conclusion, it is only based on semantic level to implement spatial data share of multi-source make real spatial information sharing of meaning can be realized. And then carry on deep research to Multi-source Spatial Data Translation Model in semantic level and explain in detail to the definition, principle, organization of the model. In order to satisfy the modal study with the need of practical application, have done the further discussion in technological route realized to physics of the model. At last, take spatial data transform platform software development project, that is subject of the land and resource information-based demonstration project--"Land and Resource spatial /non-spatial data administrative skill and the integrative information manage "—in Jiangsu Province, as an example, have carried on further practice to the practical application of the model.Main content this thesis studies is:1. Trough comparison of several ways of the spatial information sharing, we concluded that spatial data share based on semantic level is the major way of spatial information sharing.2. Trough the semantic research of GIS data, we defined the level mechanism that the geographical information sharing can be realized.3. The research of multi-source spatial data. We carry on research to the data format and the way of logic organization in present major GIS platform, auxiliary platform and the DBMS.4. Trough the research of multi-source spatial data translation model based on semantic level, we proposed a view that when the spatial data are transformed, the conflict between various kinds of spatial data models can be solved and replaced through semantic information’s inherit and expansion.5. Trough design and further use designing of transform engine of spatial data taking model as backing. We taking further research of Technological route that the model realizes.6. On the basis of analysis synthetically of the existing situation of information data to land and resource department in JiangSu province, we carry on component development to construct Jiangsu Province land and resource multi-source spatial data sharing platform—new generation spatial data transform platform to land and resource department with COM package interface~FME objects-that FME (Safe Software of Canada Company) offers.7. Necessity must be proceeded while the platform is built such as, mapping of spatial data logic model, translation under modal control, translation with semantic control, etc.
