集成遥感与GIS技术的土地利用动态变化监测方法研究

尽管国内外已发表了许多利用两个或两个以上时相遥感影像进行土地利用动态变化监测的研究成果,但鲜有基于单时相遥感影像与土地利用现状图进行土地利用动态变化监测的研究成果出现。本文将以土地利用现状GIS数据和高分辨率遥感影像为数据源,探讨利用GIS数据和相应分辨率的单时相遥感影像进行土地利用动态变化监测的有关技术方法和技术流程,并通过实验验证方法和技术流程的有效性和可行性。

An Object-based Land Cover Change Detection Approach of Using Single-temporal Satellite Image and GIS Data

While a variety of change detection approaches using multi-temporal satellite images have been reported,few approaches using GIS data of land use and single-temporal high spatial resolution satellite image have been reported.This paper proposes an object-based land cover change detection approach using single-temporal high spatial resolution satellite image and GIS data of land use.Compare with the pixel-based change detection approach,the object-based approach must be more suitable for in high spatial resolution images.To test the validity of the proposed approach,we applied it to the actual data,and primary result reveal that the proposed approach is valid.
