珠三角地区地处热带,经济发达,地物复杂多样,地域特色明显,缺乏已有经验参考,技术人员对有关分类掌握不牢、理解不准的问题较普遍。本文结合珠三角地表覆盖的自然与人文特征,分析了采用高分辨率航空影像,以内业机助人工判读为主、外业调绘为辅的技术路线,提出了基于类别常见程度的差异化判读方法,归纳了常见地物的解译标志,并对典型问题和生产经验进行了总结。
珠三角地區地處熱帶,經濟髮達,地物複雜多樣,地域特色明顯,缺乏已有經驗參攷,技術人員對有關分類掌握不牢、理解不準的問題較普遍。本文結閤珠三角地錶覆蓋的自然與人文特徵,分析瞭採用高分辨率航空影像,以內業機助人工判讀為主、外業調繪為輔的技術路線,提齣瞭基于類彆常見程度的差異化判讀方法,歸納瞭常見地物的解譯標誌,併對典型問題和生產經驗進行瞭總結。

The Pearl River Delta Region is a developed area in the Torrid Zone with complex and unique land -covers , which are dif-ferent from any other regions in China .Because of the lack of prior experience to be referenced , there are a lot of common problems for technicians to understand the basic concepts of land cover classification firmly and concisely in the geographical condition surveying of China.Firstly, the natural and cultural features of the land cover in the Pearl River Delta were discussed .Afterwards, a technological route using high resolution aerial imagery was analyzed , where the artificial interpretation in office aided by computers was used as the main method, supplemented by some field work .Furthermore, a method of image interpretation for every individual class was proposed based on the frequency of the interesting classes .Finally, the interpretation signs of frequent classes were discussed , and the typical problems and the experience in the production were summarized .
