3S技术在土地利用调查中的应用

基于无人机遥感图像的分类精度和高分辨率的图像特征,得出面向对象的遥感影像分类方法,即应用无人机遥感技术进行土地利用的快速详查信息提取。运用GIS技术,着重研究土地利用数据库的建立方法及构建过程,通过该数据库构建的时空模型,可有效地避免数据冗余问题,建立的数据库还可实现土地的详查追溯,通过图像的层次叠加获取历史土地详查的全区土地信息。

The Application of 3S Technology on Land-Use Survey

Necessary to meet the accuracy of UAV remote sensing images, but also meet the requirements of high-resolution images, it is proved that if you want to apply land-use UAV images information extraction, then the use of object-oriented remote sensing image classification method is the best option. By using GIS technology,this paper focuses on the establishment of methods of land use database and building process, By using this database, to build space-time model can effectively avoid data redundancy. The database can also be implemented retroactively land survey, the use of image-level overlay can get the region＇ s land survey land information which is in the past time.
