Hi there,

Im working with a multipart polygon.  Lets say its the state of Hawaii.  So one feature class called Hawaii (state) that contains a few polygons (whicha are the island boundaries) inside of it...all called Hawaii.

Now lets say I have 2 ft contour data for the islands only.  No bathymetric data.  So I want the output raster to reflect only where the contour data is (land only, nothing beyond the exact polygon boundary for each island).

How do I do this?  Most of the time the raster is generated using an extent boundary, but I only need data for the land (only within each polygon boundary).  The state polygon boundary does not have elevation assigned to it, as it is only a polygon.

Further, how do I get it so that the raster truely reflects the contour data, so that when I click on a contour line, the raster elevation is the same as that of the line?

Thanks,
Christi
I also want the data
