Hi,

I would like to ask if somebody knows some way, software or an algorithm which can expands existing downloaded polygon in *.poly file.

I mean I would like to move each node of the polygon more outside to create bigger polygon area.

Thank in advance

What you are (probably) looking for is a polygon buffer. There are various tools which generate buffers. Some of them:

I'm not sure they directly support .poly files, though. You will probably need to transform .poly to something these tools can work with.
