Realization of DEM

[ammiraglio15]

hi, I created the process of bilding geometry following the guide on the site Agisoft (http://www.agisoft.ru/tutorials/photoscan/05/). I want to create a dem I created the ortho but the option "DEM" is not active. I want to specify that I have correctly followed the guide except the step to enter a TXT file of the coordinates of the camera for every photo How can I generate the dem? thanks

Hello ammiraglio15,

DEM export option is available in File menu only if the model is referenced (using Ground Control pane). So you either need to input coordinates of cameras/markers positions and specify the correct coordinate system or to use scale-bars to define known distances between pair(s) of markers.
