高光谱遥感技术在土地工程中的应用分析

Application of Hyperspectral Remote Sensing Technology in Land Engineering

随着我国经济社会的发展,人们对土地需求的日益加大,土地供需矛盾日益加深,土地工程应运而生,其能够有效增加可利用土地面积,提高土地产出效率。但由于土地工程的快速发展,如何利用现代化的技术手段对实施项目进行快速、准确监测及评价显得尤为重要。高光谱遥感技术具有高光谱分辨率的特点,蕴含着丰富的地物光谱信息,地表识别能力强,地类要素的半定量或定量分析成为可能,刚好切合土地工程领域的现实需求。本文首先介绍了土地工程及高光谱遥感的概念,分析了高光谱遥感的特点及其在土地工程领域的应用,并针对目前问题提出了相关建议。

With the increasing demand for land in China's economic and social development,the contradiction between land supply and demand is deepening.After years of exploration and practice,land engineering have emerged.Land engineering can effectively increase the available land area and improve the land output efficiency.With the rapid development of land engineering,how to apply modern technology to quickly and accurately monitor and evaluate its implementation projects is particularly important.Hyperspectral remote sensing technology has the characteristics of hyperspectral resolution and contains rich spectral information of ground objects,the ability of surface recognition is greatly improved,and the quantitative or semi-quantitative analysis of land elements becomes possible.Hyperspectral remote sensing just meets the practical needs in the field of land engineering.This article first introduces the concepts of land engineering and hyperspectral remote sensing,analyzes the characteristics of hyperspectral remote sensing and its application in the field of land engineering,and puts forward relevant suggestions for current problems.
