terrain slope meaning in English
地面倾斜
Examples
- Terrain slope information can be drawn from polarimetric synthetic aperture radar ( sar ) two - dimensional image , so that three - dimensional image can be generated . it differs from two - pass or repeated trace insar that uses interference phase method to obtain topography height . the p - sar three - dimensional image technology uses the stokes matrix formed by two - dimensional images resolution cells , then applying polarimetric synthesize to stokes matrix can produce polarization signature of the scatter cross - section a - ( , x ) for any ( ellipticity ) and ( orientation ) polarization state
这种方法不同于重复轨道和双通道insar系统，不是利用干涉法提取高度信息，而是利用极化sar二维图像各分辨单元的stokes矩阵，通过极化综合估计每个分辨单元的共极化散射特性和交叉极化散射特性(极化指纹) ，以及共极化散射特性最大值时对应的极化椭圆度x利极化椭圆方向角，求解地形的高度轮廓。 - A digital elevation model ( dem ) is a digital file consisting of terrain elevations for ground positions at regularly spaced horizontal intervals . dem may be used in the generation of three - dimensional graphics displaying terrain slope , aspect ( direction of slope ) , and terrain profiles between selected points
数字高程模型( dem )是反映高程信息的数字地面模型，它是以数字的形式按一定的结构组织在一起、表示实际地形高低起伏和地形大小特征的空间分布模型。 - The main contributions of the dissertation are as following : ( 1 ) according to the theories of co - polarization and cross - polarization scattered characteristics , co - polarization and cross - polarization scattering characteristics of typical targets have been analyzed detailedly in this paper . a mechanism is described that rough surface tilted ( symmetrical distribution scene ) conduces to estimate terrain slope . so , we can estimate an elevation outline of symmetrical distribution scene without any experiential knowledge
