Research on Geographic Information System of Natural Zoning for Highway

摘要

The natural zoning for highway cannot accurately reflect the relationship between the natural geographical factors and the highway engineering. The main reasons: study lacked basic data; spatial data analysis technique fell behind; index analysis mainly relied on the subjective experience; it was difficult to fully promote the application of the zoning results. The establishment of Geographic Information System of Natural Zoning for Highway (HZ-GIS) provides the powerful tools for the research work of highway zoning: realizes the seamless integration of GIS function platform and spatial database through spatial data engine, improves the storage and utilization efficiency of spatial data; carries on the quantitative analysis of zoning indices with the intelligent model running pool; establishes the zoning results release system based on Web Service, and realizes the network distribution of zoning results.
