摘要
面向地理对象影像分析技术GEOBIA是地理信息科学中的一个正在发展的研究领域,从提出至今已有10余年的历史,受到了国际上众多研究机构的高度关注,被认为是一个不断发展的综合性学科,其基础理论、技术方法、应用推广等问题有待深入研究。因此,紧跟GEOBIA的研究动态,重点并系统分析该技术的发展历程与进展,对我国在此方面的研究定位具有重要意义。本文分析了GEOBIA技术的发展,总结归纳了现有技术方法,深入分析了GEOBIA技术的原则、优势、劣势、机遇与挑战,积极探讨了需要深入研究的科学问题,为深入研究GEOBIA理论、方法和应用奠定了基础。
Geographic object-based image analysis (GEOBIA ) is a developing technique in the field of geographic information science.It has been highly concerned by a large number of international research institutions for more than ten years.Its basic theory,technical method and application should be studied thoroughly.Therefore,it is important to track the dynamic research of GEOBIA,and analyze its progress and development.This paper analyzed the development of GEOBIA technology,summarized the methods of GEOBIA,and analyzed its strengths,weaknesses,opportunities and challenge.At last the science questions for further study were explored which make the basis for the study of GEOBIA theories,methods and applications.
