1. It was intended to symbolize the triangulation method used in surveying. 2. By this time, triangulation methods were by then well established for local map-making. 3. For each triangulation method , it can be determined if this last relation is valid. 4. The main difference between LSM algorithm and the direct triangulation method is the noise. 5. Not every triangulation method assures invariance, at least not for general types of coordinate transformations. 6. A point in this subset is then a " singularity " of the triangulation method . 7. Which triangulation method is chosen for a particular problem depends to some extent on these characteristics. 8. The triangulation method is safer as there is nothing transmitted towards the target as in the laser rangefinder case. 9. Cross-triangulation methods can be used. 10. The Italians then followed regular triangulation methods to measure the height of the summit from these carefully plotted base lines.
