Shapely affine transform

WebbAffine transformations do not necessarily preserve either distances or angles, but affine transformations map straight lines to straight lines and affine transformations preserve ratios of distances along straight lines (see Figure 1). For example, affine transformations map midpoints to midpoints. In this lecture we are going WebbGeoSeries.affine_transform(matrix) [source] # Return a GeoSeries with translated geometries. See …
