目前,县级土地利用现状详查正在全国展开,卫片资料因分辨率较低,地形图又陈旧,很难满足县级土地利用现状详查的要求。利用18MSP多光谱航空遥感,可以满足县级土地资源详查。本文以深圳地区为例,就利用18MSP多光谱航片进行土地利用现状详查方法作探讨性研究。一、18MSP多光谱航片与土地利用类型的相关分析 18MSP多光谱航摄是采用三台18×18cm相幅的航摄仪、三个滤光镜和三种胶片同步拍摄记录的影像。深圳地区所摄多光谱航片,航高为6000米,比例
At present, the detailed investigation on the current situation of county-level land use is under way across the country. Because of the low resolution and the obsolete topographic map, the information of county-level land use is difficult to meet the requirements of detailed investigation on the status quo of land use at county level. Using 18MSP multi-spectral aviation remote sensing, to meet the county-level land resources detailed investigation. Taking Shenzhen as an example, this paper makes a exploratory study on the detailed investigation of land use status using 18MSP multi-spectrum aerial photos. 18MSP multi-spectrum aerial photos and land use types of correlation analysis 18MSP multi-spectrum aerial photography is the use of three 18 × 18cm phase amplitude aerial camera, three filters and three films simultaneously recorded images. Multi-spectrum aerial photos taken in Shenzhen, aerial height of 6,000 meters, the ratio
