室内航片的土壤判读,是根据掌握的航空摄影成象规律知识和工作地区有关土壤及其他地理要素的了解来进行的。一般先浏览象片的镶辑图,以便了解和掌握调查地区的全貌概况。再逐张象片在立体镜下仔细的分析地形特征、立体形状、色调等航片的土壤判读。 室内航片的土壤判读顺序,是从全部到局部,从一般到个别,从重要到次要,从粗到细。对具体土壤的判断确定,一般说来都是先根据地形、植被等景观要素的特点,划分出大小各级景观类型,然后分析各级景观类型中可能出现的土壤类型及其特性。 室内航片的土壤判读,主要根据影象轮廓的色调、形状、大小、图形、结构和阴影等这些重要的影象特点来实现的。有时通过这些标志判读出地形、母质、水文、植物类型、作物种类和土地利用现状等与土壤形成、特性和分布有关的因素。然后,再推断土壤类型。但有时也可通过这些影象特点直接确定土壤
The interpretation of soils for indoor aerial photos is based on knowledge of the laws of aerial photogrammetry and knowledge of the soil and other geography in the area of work. General first browse the image of the gallery in order to understand and master the overview of the survey area. And then by a piece of photos in the three-dimensional mirror careful analysis of terrain features, three-dimensional shape, color and other aerial photos of soil interpretation. Indoor airborne soil interpretation order, from all to the local, from general to individual, from important to secondary, from coarse to fine. The determination of specific soils is generally based on the characteristics of landscape elements such as topography and vegetation, and the classification of landscape types at all levels, and then analyzes the possible types of soil and their characteristics at all levels of landscape types. The interpretation of the soil in indoor aircrafts is mainly based on the important image features such as the hue, shape, size, shape, structure and shadow of the outline of the image. These signs are sometimes used to interpret factors related to soil formation, characteristics and distribution, such as topography, parent material, hydrology, plant type, crop type and status of land use. Then infer the soil type. However, it is sometimes possible to determine the soil directly from these image features
