面向对象的遥感影像水域信息提取应用研究——以西藏(东)地区为例

Research on Water Information Auto-Extraction with Object-Oriented Remote Sensing Image——Taking Tibet (East) Region as an Example

以西藏(东)地区为例,选用高分辨率卫星遥感影像,根据地理国情普查内容与指标,选择地表覆盖分类中的水域作为分类研究目标,通过特征分析与流程设计,形成适用于该地区特定影像的面向对象的水域信息提取方案。生产应用测试验证了该方案在地表覆盖信息自动提取方面应用的可行性。

Based on the content and index specification of nat- ural geographical census, in order to get the water covered graphic information, this paper sets Tibet （east） region as test area and high resolution satellite remote sensing image as test data, proposes the water information auto-extraction program by using feature analysis and process design. The application in production project show that the program can be used for water covered graphic information auto-extraction.
