基础地理信息数据在LBS应用中的信息提取与处理

通过分析LBS数据应用范围和基础地理信息数据的内容及特点,详细介绍了在LBS应用中基础地理信息数据内容可提取性及可整合性,确定了除所需的专题地理信息数据具体内容外,在LBS应用中城市、城际数据所需基础地理信息数据的比例尺、要素内容,以及不同比例尺数据的整合处理方案、要素提取与处理的方式与方法。这样对于位置服务的数据处理可以按照比较规范的方式、方法进行,也为盘活基础地理信息数据资源提供了较好的思路,更好地实现基础地理信息数据公众化服务。

Information Extraction and Process of Fundamental Geographic Information Data for the Application in LBS

This paper firstly analyzed the application scope of Location Based Service (LBS) and the contents and character of fundamental geographic information data. Then it introduced the feasibility of extraction and integration of fundamental geographic information data for the application in LBS. It identified the contents of thematic geographic information data, the scale and feature contents of fundamental geographic information data in city and region scale, the integration process schema for different scale data, and the methods for the feature extraction and process for the application in LBS. Thus, the location based data process can be implemented according to the standardized methods. It provides the new thought for utilizing the resources of fundamental geographic information data and realizing its public services.
