creating a raster of distance to the interior of a polygon

[AnnaEstes]

Hi there,

I have a polygon representing a protected area, and I would like to use distance to PA boundary as one of a set of variables in an analysis. This is no problem for distance out from the protected area - I use distance to line in Spatial Analyst. Now I would like to do the same in reverse - to get a continuous distance raster going from the PA boundary to the interior of the polygon. If anyone has any ideas about how to accomplish this, I would be most grateful!

Many thanks.

One approach may be:
- convert Polygon To Line (if you don't have ArcInfo license, use ET GeoWizards)
- calculate Euclidean Distance from lines (distance will be calculated from both sides of a line, when line will have 0)
Example:

Thanks, Marcin! Worked like a charm. I appreciate your help.
