Image Mosaics from Swedish Weather Radars
This paper describes the principles for merging data from the Swedish digital weather radars into one image. The main principle is that data as close to the ground as possible should be displayed. That is, if a pixel (horizontal size 2*2 or 1*1 square km) is depicted by two or more radars, the information from the radar having the lowest lower border of the beam is selected. This demands a knowledge of the elevation angles to obstacles for each radar.
