遥感是从天空来感知地球表面物体特性的一门新兴、综合探测技术,是应用摄影技术在天空进行测绘的一种方法,过去简称航测,现统称遥感。航空遥感所获取的资料比常规测量方法具有测绘面积大、视域广、速度快、信息真、用途广等特点。是当前我国测绘1:1000～1:100000各种比例尺地形图的主要方法。已应用于铁路、公路、输油管道选线、勘测设计、森
Remote Sensing is an emerging and comprehensive exploration technique of sensing the characteristics of objects on the surface of the earth from the sky. It is a method of mapping in the sky by using photographic techniques. The information acquired by aviation remote sensing has the characteristics of large surveying area, wide field of view, fast speed, true information and wide application as compared with conventional surveying methods. It is the main method of surveying and mapping 1: 1000 ~ 1: 100000 topographic maps of various scales in our country at present. Has been used in railways, highways, oil pipelines, surveying and design, Sen
