The Analysis of Single Polarization Synthetic Aperture Radar Images for the Application of Land-use and Land-cover Change
|
Abstract:
For the investigation of land use and land cover change,taking the limitation of optical remote sensing in rainy or cloudy regions of China into consideration,synthetic aperture radar (SAR) can be an alternative way.In this paper,we first introduce an object-oriented imagery segmentation and classification software named Definiens Developer for the land use classification of single polarization spaceborne SAR images,including median resolution spaceborne SAR( take ENVISAT ASAR and Radarsat-1 as examples) and high resolution spaceborne SAR(take TerraSAR-X as an example).Then,we estimate the classification accuracy and analyze the potentials for the two modes spaceborne SAR images in the classification of land use and land cover change.In this part,conclusions for the interpretation of their corresponding SAR images are also given.
