In gdalwarp we have at least two options for managing of output size of a raster:
- -tr xres yres: set output file resolution (in target georeferenced units)
- -ts width height: set output file size in pixels and lines
In rasterio we have the following function:
- rasterio.warp.calculate_default_transform(src_crs, dst_crs, width, height, left=None, bottom=None, right=None, top=None, gcps=None, resolution=None)
If I understood correctly resolution
argument has the same meaning as tr
But how I can calculate transformation (destination affine first of all) if I know output dimensions (width and height)?
In other words I'm looking for how I can achieve the same result with rasterio as with gdalwarp ts
I hope what I have requested is possible.
