摘要
环境减灾二号A/B卫星在轨测试期间,根据自然资源行业典型应用领域相关行业标准和技术规范,对卫星CCD和高光谱(HSI)数据的应用能力开展评价及总结,对存在的问题进行了初步分析。测试结果表明:可见近红外数据图面清晰度好,细节地物表现能力强,信息量丰富,1∶25万遥感调查监测的可解译性高;高光谱数据光谱信息丰富,在矿物识别方面可进行定量反演;可为自然资源典型业务领域调查监测提供重要的数据支撑保障,对环境减灾二号A/B卫星数据的大规模应用与后续星的研发具有参考意义。
In the on-orbit test, according to the technical standard in the typical application fields of the natural resources, the application capabilities of the CCD and HSI data of the HJ-2 A/B satellites were evaluated and summarized, and the existing problems were preliminarily analyzed. The test results show that the visible and near-infrared data which has good image clarity, rich information, strong expression of detailed features, and high interpretability, which can be used for 1∶250 000 remote sensing survey monitoring. The hyperspectral data with abundant spectral information is useful in quantitative inversion of mineral identification. It can provide important data support for the investigation and monitoring of natural resources typical applications. This research has reference significance for the large-scale application of the HJ-2 A/B satellites data and the development of subsequent satellites.
