I have sheetline geometries for the German TK50 1:50.000 map extents. I now want to create an atlas for the geometries. So far no problem, I have this working.
But the sheetline geometries cover 40' long and 24' lat, which always results in the height of 22.2 km but varying widths between 25.2 and 21.2 km. I know I can programmatically adjust the size of the drawn map but therefore I need to figure out the width. The geometries come projected EPSG:25832 (ETRS89 / UTM zone 32N). This makes them turned and that results in bounds_width not getting the right width of the sheetline widthwise.
Can anyone point me in the right direction? I mean I can't be the first one trying to recreate a map by a given sheetline.
