基于PDA的城市实体信息采集系统设计与实现

Design and implement of urban entity information collection based on PDA

现有数字城市模型大多缺乏对模型属性信息的认知表达手段,本文设计了一种基于PDA的城市实体信息采集系统,系统支持坐标数据和文本、图像、视频等多种非格式化数据格式的输入输出,实践结果表明该系统能够满足城市实体信息数据属性信息获取的应用需求。

Most of digital city models are lack of recognition of attribute information,the paper has designed a collection system of city entity information,and the system support data input and output of coordination 、text、image and video etc,it is proved that the system can fulfill the requirement of city entity information.
