3) Spatial resolution refers to the size of a pixel that is recorded in a raster image -typically pixels may correspond to square areas ranging in side length from 1 to 1000 metres. 空间分辩率是指摄录在栅格图像中像素的大小一典型的像素相当于 边长为一至一千米的任一正方形面积。 注释:名中that关系代词,引导定语从句修饰先行词 a pixel;破折 号后面的内容属于 a pixel的同位语,用来对 a pixe做进一步解释; 而 ranging则是现在分词短语做定语,修饰 square areas。 4)For example, in conventional photographs, distances are accurate in the centre of the image, with the distortion of measurements increasing the farther you get from the centre 例如,在传统的照片里,远景通常要非常精确地置于图像中心,因 为如果离中心越远,失真度就会越大。 注释:句中wth+n+v-ing构成独立结构,作状语,表原因。 2021/2/20 P3
