目前,我国正在全国范围内进行土地资源调查。为了探讨利用遥感技术及时、详细、准确、经济地进行大面积土地资源调查,本文想以利用彩色红外航空象片完成天津市土地利用现状详查和对北京地区TM图象初步分析的结果为例作些讨论。一、彩色红外航空象片和TM图象在地类识别中的应用 (一)彩色红外航空象片的应用 通过利用1:5万放大至1:2.5万的彩色红外航空象片进行天津市土地利用现状详查工作,我们认为,大比例尺彩色红外航空象片,可以满足我国东部农业区土地利用现状详
At present, China is conducting land resources surveys nationwide. In order to explore the timely, detailed, accurate and economical investigation of large-scale land resources using remote sensing technology, this paper attempts to make a detailed investigation on the status quo of land use in Tianjin by using color infrared aerial photographs and the preliminary analysis of TM images in Beijing as an example Make some discussion. First, the color infrared aerial images and TM image recognition in the land class (A) the application of color infrared aerial image By using 1: 50000 enlarged to 1: 25000 color infrared aerial image of Tianjin land Using the current situation of detailed investigation, we believe that large-scale color infrared aerial photographs can meet the actual conditions of land use in the agricultural areas in eastern China
