Combining Optical and Radar Satellite Imagery to Investigate the Surface Properties and Evolution of the Lordsburg Playa, New Mexico, USA

This data repository includes data and codes for the application of linear spectral unmixing and Interferometric Synthetic Aperture Radar (InSAR) technique for the optical and radar satellite remote sensing imagery products in the Lordsburg Playa, New Mexico, USA. Linear spectral unmixing was applied on optical images from Landsat and Sentinel-2, and InSAR technique on SAR images from Sentinel-1. The "Google_Earth_Engine_Javascript" dataset is the Google Earth Engine Javascript codes used for the linear spectral unmixing using Landsat images (Landsat 5 and 8) and Sentinel-2. The "Spectral_Signature_of_Endmembers" is the dataset of spectral signatures of the endmembers (soil, vegetation, and water). The "Synthetic_Aperture_Radar_Images" is the list of the synthetic aperture radar (SAR) images used for the Interferometric Synthetic Aperture Radar (InSAR) technique.本数据集仓库收录了用于美国新墨西哥州洛兹堡干盐湖（Lordsburg Playa）光学与雷达卫星遥感影像产品的线性光谱解混（linear spectral unmixing）及干涉合成孔径雷达（Interferometric Synthetic Aperture Radar, InSAR）技术应用所需的数据与代码。其中，针对Landsat与Sentinel-2的光学影像采用线性光谱解混方法，针对Sentinel-1的合成孔径雷达（SAR）影像则采用InSAR技术。"Google_Earth_Engine_Javascript"数据集包含用于基于Landsat 5、Landsat 8及Sentinel-2影像开展线性光谱解混的谷歌地球引擎（Google Earth Engine）JavaScript代码。"Spectral_Signature_of_Endmembers"数据集包含端元（endmembers）的光谱特征数据，涵盖土壤、植被与水体三类端元。"Synthetic_Aperture_Radar_Images"数据集包含用于干涉合成孔径雷达（InSAR）技术的合成孔径雷达（SAR）影像清单。
