农业是遥感应用的大户之一,随着空间技术的开发利用,农业遥感已形成低空、中空、高空到外空的多层次配合;并从定性观察向定量探测,从静态研究到动态监测,从单项分析到综合评价,从判读制图到宏观决策的方向发展,其研究、应用逐渐深化,也在某些方面取得可观进展。一、农业遥感应用进展 1.土壤调查、分类与制图:土壤与土地利用调查是航空遥感用于农业的最初项目。自20年代起利用黑白航片,60年代引入彩色航片,60年代末试用机载多光谱扫描资料及彩红外
Agriculture is one of the large-scale applications of remote sensing. With the development and utilization of space technology, agricultural remote sensing has formed multi-level cooperation in low altitude, hollow and altitude to outer space. From qualitative observation to quantitative exploration, from static research to dynamic monitoring, From single analysis to comprehensive evaluation, from the direction of interpretation and mapping to the macro-decision-making, the research and application are gradually deepened and considerable progress is made in some aspects. I. Advances in Agricultural Remote Sensing Applications 1. Soil Survey, Classification and Mapping: Soil and land use surveys are the initial project for the use of aerial remote sensing for agriculture. Since the 1920’s the use of black and white aerial photos, the introduction of color aerial photos in the 1960s, 60s pilot airborne multispectral scanning data and color infrared
