 First, we have to use the embedded GNSS data to set ("bascule") our system in the geographical coordinate system of choice (here a local radial tangential system - RTL) :

+<pre>mm3d CenterBascule "R.*.JPG" All-Rel Nav-Brut-RTL tmp CalcV=1</pre>
 Note : the target system NEEDS to be at least pseudo-euclidean (axes orthonormales). Lat/long/height is not such a system.

 ==Absolute orientation and correction of the GNSS delay==
 The position of the UAV are computed for the phase center of the GNSS which not correspond to the camera center. Moreover, the UAV is moving when you take the picture so you have to compute relative speed of each camera in order to determine and correct GNSS systematic error(delay).

-Here we want to use the canopy model in other tools such OTB or QGIS for image segmentation/classification. So we have to backward transform our orientation coordinate system from local euclidian system to a geographic system. The tool to perform this transform is ChgSysCo. Here we transform to Belgian Lambert 72 (EPSG31370). More information about EPSG codes here : <code>http://spatialreference.org/ref/epsg/</code>

 This dataset will allow you to process a UAV mission a more generally a aerial mission. You will go trough direct georeferencing, GNSS delay correction, coordinate system change. We apply all this concepts to canopy model generation.
