利用面向对象分类技术进行地理要素快速更新的方法研究

Fast Features Revision by Object-oriented Classification Method

摘要:

该文以遥感影像为更新期数据，利用面向对象分类方法，在对象层次进行推理和分析；将更新完成要素作为先验知识，分层更新地理要素；对更新过程中基期地形图专题要素不变信息的利用，主要地理要素提取和更新方法进行了研究。结果表明，该方法兼顾地理要素快速更新的自动化与实用化，具有广阔的应用空间。

Abstract:

In this paper, regarding remote sensing images as the update datas, using object-oriented classification method, on the object level, conduction and analysis are carried out. Regarding updated and finished elemetns as the prior knowledge, geographical elements are hierarchically updated. The use of unchanged information duing the update period of topographic map and main geographical elements and updating methods are studied. As showed by the results, this method has the characterisitics of fast and practical in automatically updating information and has a broad application space.
