Hello,
I would like to change the pixel size of an orthophoto from 50cm to 20cm. I tried it with the PROJECT module but I get an error that there is no plane.ref file.
The original image has a plane ref. system and the output file should also have a plane ref. system. The original image has 6000 x 6000 pixels and the output image should have 15000 x 15000 pixels.
From IDIRISI help (module PROJECT):
10. PROJECT may be used to change the resolution of an image by a non-integer multiple. To do so, indicate the same output reference system as the current reference system, then give the desired number of rows and columns for the resulting image. Choose whether to use a nearest neighbor or bilinear resampling. To make the resolution smaller by an integer value, EXPAND may be used. To make the resolution larger by an integer value, CONTRACT may be used.
Regards, Rolf
