摘要
专题制图中利用遥感技术获取专题要素和地理底图要素已成为大势所趋,而如何实现面状要素中轴线的提取从而获得线状道路、线状河流等底图要素一直是GIS界研究的热点。本文通过对ArcGIS9.0中提供的各种功能模块的综合应用实现了面状要素中轴线的自动提取。经实验这种方法简单实用、效果理想,效率很高。
Thematic mapping, the use of remote sensing technology acquisition thematic elements and geographical base elements have become the trend of the times, and how to achieve a face-shaped elements axis extraction method to obtain roads, rivers, etc. base features have been developed GIS sector research hot spots. All through ArcGIS9.0 various functional modules provide an integrated application of the face-shaped elements axis automatic extraction. After this method simple practical experiments, the results are satisfactory, high efficiency.
