 ====Measurement process====
-*1. Measurements of almost 3 support points on the facade n°1 (At least one point should be measured to be valid on at least two images). To set the points, you need to get to know the the position of the 3 points thanks to the folder 001_Elements-de-georeferencement. <pre>mm3d SaisieAppuisInitQT "facade1DSC0589[8|9].JPG" MEP 1001 MesureFacade.xml</pre>

 All the images should be set up simultaneously, in order that the georeference process will be expressed into one only cordinate system. First, we can run the tie-points search : <pre>mm3d Tapioca MulScale ".*JPG" 600 2000</pre>
