多时相和多种比例尺彩色和彩红外航空摄影,由 Sakaerat 环境研究站在81.05km~2 上进行过试验。从这些相片上进行了森林土地利用分类并编制植被图。研究结果表明1/15000的大比例尺相片,为森林土地利用分类提供详细的资料。例如:能识别林分密度、森林群丛、发育阶段、干扰程度、优势树种的分布等等。多时相彩色和彩红外摄影也能提供物候征、森林火灾(新老火烧地)、森林交错群落和农作物类型等信息。
Multi-temporal and multi-scale color and color IR aerial photography, conducted by the Sakaerat Environmental Research Station at 81.05km ~ 2. From these photos, forest land use classification and vegetation map were compiled. The results show that 1/15000 large scale photos provide detailed information for forest land use classification. For example: can identify stand density, forest cluster, stage of development, the degree of interference, the distribution of dominant species and so on. Multi-temporal color and color infrared photography can also provide information such as phenology, forest fires (old and new), staggered communities and crop types.
