Hi Gustavo,

to clip an image with OTB you can use the ExtractROI application (from
command line, graphical user interface or Python):

https://www.orfeo-toolbox.org/CookBook/Applications/app_ExtractROI.html

The application is quite versatile as you can define the clip region with
several methods (pixel coordinates express in different geometries, size,
radius around a coordinates...)

To clip the image with a polygon vector you can you the mode 'fit' and the
option '-mode.fit.vect' to specify the input vector file which will be used
to define the region of interest.

Hope it helps.

Manuel

Is this function deprecated. I have been running the attached script and
get the error ## exception thrown in otbApplication. Could not find
parameter vect.

Hi Gabrielle,

did you install 6.4 version with the standalone otb archive available on
orfeo-toolbox.org? What is your operating system?

Finally, can you send the script as a text file instead as a png to
facilitate the test on my side.

Thanks in advance.

Manuel
