本文简要介绍利用我国科学探测和技术试验卫星(简称:我国卫星)图像数据进行信息提取的试验,目的是评价我国卫星图像数据的几何校正精度、光谱信息量及其应用价值。在图像处理试验过程中引入生物量概念,使植被信息得以显著增强,尤其是生长在水渠、池塘中的植被,其分布特征清晰反映在生物量图像上。说明我国卫星图像资料在环境监测、土地利用调查、植被覆盖填图乃至农作物调查和农业产量预测中具有潜在的应用价值。
This article briefly introduces the experiment of information extraction using the image data of China’s scientific exploration and technology test satellite (referred to as China’s satellite) for the purpose of assessing the geometric correction accuracy, the amount of spectral information and its application value in China’s satellite image data. In the process of image processing, the concept of biomass was introduced to make the vegetation information significantly enhanced, especially the vegetation growing in aqueducts and ponds, whose distribution features are clearly reflected in the biomass images. It shows that our satellite imagery data have potential application value in environmental monitoring, land use survey, vegetation cover mapping and even crop investigation and agricultural yield forecasting.
