| 摘 要： | 土地利用数据库对于土地管理、土地动态检测和土地变更调查具有重要的意义。本文主要介绍了建立土地利用数据库的技术方法和工作流程。以张家界市武陵源区为例,采用面向对象的分类方法对高分辨率遥感影像进行分割和自动分类,将分类结果导入GIS环境下,进行拓扑构建和属性编辑,实现图形数据、属性数据的关联,最后完成土地利用现状数据建库。上述方法有效提高了建库质量和建库水平,并取得了很好的效果。

| Abstract: | Land use database is very significant in land management,Land-use dynamic monitor and land change survey.This paper mainly introduces the technical flow for construction of land use database.A case study for Wu ling yuan district of Zhang Jia Jie is performed.Based on object-oriented,the new classification method segments the high resolution images quickly and classifies them automatically.The classification result can be translated into various GIS platforms effectively for topological building and properties editing to correlate graphic data with attribute data,and then the Land Survey Database is completed.Experiment indicates that this method can improve the quality and level of database construction effectively,and get a favorable effect. |
