Current GISs lack efficient management and analysis functions for coastline dynamic changes for coastline is a special line object .

现有地理信息系统对于海岸线这一独特线对象的动态变化缺乏有效的管理和分析手段。

United Structure of Point-Arc for Network Graph and It 's Application in GISs Shortest Path Searching

图的节点-弧段联合结构表示法及其在GIS最优路径选取中的应用

( GISS ) Geographical information server system . ( GISS ) is a large system project , including GIS ( geographical information system ) . Internet database technology and so on technique .

地理信息服务体系，是一个涉及到GIS、Internet网络、数据库等众多领域的系统工程，其所涉及的技术很多。

But most of current GISs are static in essence , they cannot represent temporal information and temporal topology , and have not rich functionality of multitemporal analysis .

但现有GIS本质上都是静态系统，不仅无法完善地表达时间变量及时空拓扑，也没有提供充足的时空分析功能。

Completely changing or largely modifying data model of current GISs and developing a lot of spatial process models which may have very narrow applications could not be accepted by the GIS vendors .

完全改变或较大修改数据模型，并开发大量的但可能只具有较窄的应用范围的时空分析模型不会被GIS开发者所接受。

This composition table provides a basis for reasoning about indeterminacy in spatial data and makes a preliminary theoretic attempt for the emergence of spatial databases and GISs capable of coping with indeterminacy .

关系复合表的建立为空间数据不确定性处理建立了推理基础，并为建立能处理不确定性的空间数据库和地理信息系统做了理论准备。

Based on the lost packets phenomenon , we put forward kinds of more general protocols : general Input-to-State stable ( gISS ) protocols , which include the widely used static protocols and dynamic protocols as special cases .

对于现有文献中广泛考虑的静态协议和动态协议，基于丢包现象，提出了一类更加一般的常规输入-状态稳定性协议。

This paper provides a review of research on uncertainties in geographical information systems ( GISs ) . This is followed by a description of a new method for deriving ε error band models based on the concepts of fields and fuzzy sets .

简述了过去研究空间数据不确定性的方法及其缺点，提出了一个基于地理数据场模型和模糊集合论的生成ε－误差带的新方法。
