天宫一号高光谱成像仪具有空间分辨率高、光谱分辨率高、图谱合一等特性,在中国航天高光谱领域具有里程碑的意义。针对一般遥感场景分类数据集尺度单一、光谱分辨率较低等问题,本文提出基于天宫一号的多谱段、高空间分辨率、多时相高光谱遥感场景分类数据集(TG1HRSSC)。利用天宫一号高光谱成像仪获取的高质量数据,经过辐射校正、几何校正、空间裁剪、波段筛选、数据质量分析与控制等,制作了一批通用的航天高光谱遥感场景分类数据集,通过载人航天空间应用数据推广服务平台(
Remote sensing image scene classification is an important means of remote sensing image interpretation, which has important application value in land and resources investigation, ecological environment monitoring, disaster assessment, target interpretation and so on. In recent years, deep learning has become a research hotspot in the field of remote sensing scene classification, and data set is the basis for its development. Most of the existing remote sensing scene classification datasets are true color images with single scale and less spectral information. And other hyperspectral data sets have relatively small data coverage. The data of Tiangong-1 Hyperspectral Imager has the characteristics of high spatial resolution, high hyperspectral resolution and wide coverage. It can be used for comprehensive feature extraction and analysis of spectral spatial information, which can provide more abundant data sources for remote sensing image classification application research, and make up for the deficiency of spectral information and limited application of common remote sensing scene classification data sets. In this study, based on the high-quality data acquired by Tiangong-1 Hyperspectral Imager, Tiangong-1 Hyperspectral Remote Sensing Scene Classification data set (TG1HRSSC) is produced through radiation correction, geometric correction, spatial clipping, band screening, and data quality analysis and control. The dataset, which contains the 204 hyperspectral multiresolution image data of nine typical scenes (e.g., city, farmland, forest, pond culture, desert, lake, river and airport), is published and shared in the Space Application Data Promoting Service Platform for China Manned Space Engineering (
