 * With the tool [[ChgSysCo]].
 * With other tools such [[OriConvert]] or [[GCPConvert]] and the option ChSys.
 For both case, you have to use the same syntax :

-Photogrammetry is often accompagned with a georeferencement (direct or indirect). The geographic position of targets or images is usually given in geographic system such WGS84 or RGF93 (France). To work with this coordinates in MicMac, yo have to transform it in a euclidian system. Best way is to work in a Local frame (RTL) define by the coordinates of one point of the field.

To work with this coordinates in MicMac, you have to transform them in an Euclidian system. The best way to do this is to work in a Local frame (RTL) defined from the coordinates of one (central) point of the field.
