The Research on Data Organization Technology in the Highway Geographic Information System

摘要：

Data are the basis of GIS.It has direct impact on the efficiency and function of a Highway Geographic Information System (HGIS),because of the characteristics of data model and data organization of the traffic geographic information system such as spatial property,multi-path network,linearity.This paper discussed the data property of HGIS,studied and presented the HGIS spatial data on multi-source and model.Also,it described and verified highway geographical feature of special subject datas linearity,dynamic and multiple-path network property in HGIS.

关键词： HGIS data management multi-source data linearity reference system highway dynamic segments
