多尺度基础地理信息数据融合模型研究——以咸阳市为例

Research on Integration Model of Multi-scale Basic Geographic Information Data:Taking Xianyang City as an Example

多尺度基础地理信息数据融合模型研究技术突破了传统基础测绘下按比例尺存储数据的生产模式,可以最大化获得已有数据最新的高质量信息,形成信息丰富、应用面广、适用性强的多尺度基础地理信息数据库。本文以咸阳市为例,设计了多尺度基础地理信息数据融合的最佳尺度分区方案和多尺度数据融合模型,基于此,提出了多尺度数据融合内容以及融合方法,解决了多尺度数据重复生产和不一致问题,实现了空间数据的纵向共享和一库管理。

Research on the multi-scale basic geographic information data integration modeltechnology,the traditional stored data production mode of basic surveying and mapping data by the scale that is broken,the latest high-quality datais obtained,the multi-scale basic geographic information database with rich information,wide application and high applicability is formed.In this paper,taking Xianyang City as an example,the best scaled divisionscheme and the integration model of multi-scale basic geographic information data integration are designed.Based on this,the content and method of multi-scale data integration are proposed.In addition,this paper solves the problem of repeated production and inconsistency of multi-scale data,and realizes the vertical share and unified management of the spatial data.
