Hi,

Can you post the exact command-line, as well as more insight on your training data (number of polygons, typical size of polygons ...) ?

Regards,

Julien

Hi

I have to work with OTB on my Training to make supervised classification about forest cover to determined wich species are present. I work especially with IGN (french established of geography) photos (0.5cm of spatial resolution) in a territory of 700 square kilometer.

Howether when I try to make some processing (not necessarily the same process) I have every time the message error ''failled to allocate memory for image" about the image I want to make. I have this message even if I put the outpout image on a virgin hard drive and even if the image are not very big (150mo). This message appear when I use monteverdi, otbgui or otbcli on OSGeo4W.

How can I resolve this problem ? Thanks for your answers

Clovis
