遥感技术在土地更新调查中的应用
首发时间:2006-09-08
摘要:土地资源是人类赖以生存和发展的基础,是国土资源的重要组成部分。本文以某城市的部分影像图为研究对象,利用SPOT5 10m的多光谱数据和2.5m全色数据,针对土地利用遥感分类中的影像预处理、影像融合、影像判读方法和土地利用现状信息如何更新等问题开展研究,以期获得适合利用SPOT5卫星影像来更新1:1万土地利用现状信息的技术方法。但是实践证明计算机分类不适合运用在对1:1万土地利用现状信息的更新工作中,而人机交互目视判读是一个最佳方法。

Application of Remote Sensing in Land Updating and Survey
Abstract:Land is the most basic resource for our living and development and it is also a important part of our country resource. This article use some image pictures of one city as research objects. The research use multispectrum data of SPOT5 10m and 2.5m panchromatic data in remote sensing image in preinterpret , image merge , image interpretation method and the method of land utilize current situation information upgrading etc. expect acquire the method of use of SPOT5 satellite image in upgrade 1:10000 land use information. But practice prove it is unsuitable to updating 1:10000 land for computer to classify.And it is a best method that the human-computer interaction to interpret the image.
Keywords: remote sensing land update image preinterpret eye interpret
