河南省地矿局科研所遥感组,1985～1986年在鸣皋幅1:5万区调中进行了遥感地质试验,取得了较好的地质成果和经济效益。该图幅位于河南省中西部,属中低山区,区内主要为元古界地层,基岩大部裸露,故其地质解译程度较高。这次遥感试验所使用的航片,是1984年4月地矿部摄制的1:2万比例尺的彩色红外航片。经过试验表明,彩色红外片明显优于黑白航片,由于彩色红外片分辨率高,在测区内大于1m的岩层一般都能解译出来,因此它可以获得黑白航片和野外不易觉察的一些信息,例如图幅北
Henan Province Bureau of Geology and Mineral Resources Institute of Remote Sensing, from 1985 to 1986 in the Ming Gao amplitude 1: 50000 regional adjustment carried out remote sensing geological experiments, and achieved good geological results and economic benefits. The map is located in the central and western Henan Province, is a low mountainous area, mainly in the area of the Proterozoic strata, most of the bedrock bare, so the geological interpretation of a higher degree. The aerial photographs used in this remote sensing experiment are the 1: 20,000 scale color infrared aerial photos taken by the Mines Department in April 1984. Experiments show that the color infrared chip is obviously superior to the black and white aviation chip. Because of the high resolution of the color infrared chip, rock formations larger than 1 m in the survey area can generally be interpreted, so it can obtain black-and-white aerial photos and some unobtrusive in the field Information, such as map north
