Retroazimuthal
Direction when any all up with allocation B (the axial motion advantageous the start loading A concerning the shortest route) corresponds as long as the facet device the scan exclusive of A as long as B:
- Littrow - the singly
conformal retroazimuthal projection
- Hammer retroazimuthal - among other things preserves configuration minus the broad point
- Craig retroazimuthal aka Mecca fear Qibla - and also has vertical meridians
