| 摘 要： | 本文主要研究通过高分辨率遥感影像和eCognition软件,利用面向对象信息提取技术来获取村庄尺度土地利用类型空间数据的技术方法。本项研究中的实验区主要地物包括麦田、旱作物、荒地、苗圃、道路、水体、建设用地和树木等类型。通过设置不同的分割参数并目视判定待识别地类的轮廓分割效果,获取适用于村庄尺度土地利用类型分类的最优分割参数,并通过分类精度对比说明面向对象信息提取相对于传统分类方法的巨大优势。

| Abstract: | This paper mainly studied the approaches of obtaining village-scaled spatial data of land use type through high-resolution remote sensing image and eCognition software,using object-oriented information extraction technology.The main features of the study area included wheat,upland crops,wasteland,nurseries,roads,water,construction land and trees etc.By setting different division parameters and visual judgments to identify the contour segmentation effect of the classes,the optimal bipartition parameters for village-scaled land use classification were obtained,and the significant advantage of object-oriented information extraction comparing with the traditional classification method was proved through the classification accuracy results. |
