Dear all,

I have a very large BINARY image (60,000x50,000 pixels) and need to generate
the distance map from the 1 values.
When the images are small than my image, I can generate the distance map
using ArcGis (my image is in .IMG format), but ArcGis return error for this
large one.

I am running R 2.7.1 under windows/xp. Is there a way of do this job using R
ou RSaga? (unfortunately I don´t have GRASS installed), and my experience
with RSAGA is near zero. My computer is 4GB ram.  I can load the images on
ArcGis and Erdas without problem, but I only don´t know how do this task.

Sorry for not send a reproducible code.

Any help are welcome.
