Creating a very hi resolution hillshade for a specific map scale lower than 1:5,000 ?

[PROBERT68]

Hi

I'm working on a map that has campground for our Forest. I am going to set the map scale lower than 1:5,000 .What I would like to know if there is a way that can I creating a smoother detail for hillshade lower than Map scale 1,500 ?

If you have a hillshade and DEM add to ArcMap, you know it will look like a grainny or fuzzy. Is there a way around to make them smoother ? Is that a possibility to do that ?

I have the 10m DEM and Hillshade here.

My plan was to export them to about 1,2000 map scale

Have you considered converting DEM to TIN? Requires 3D Analyst or third party tools..

I could do that. Why Tin ?

[DarrenWiens2]

Because TINs will appear sharp at any resolution. Whether or not the triangles will work for your map, I don't know.

You can also try Resampling your DEM raster to a smaller cell size.

OK, this is something I will give a try. Thanks ! Also, the reason why  I post was because I wanted to know if others have already did the same thing what I am going to do.

There are some recent additions to arcscripts 2.0 beta that you might find interesting as well

Very useful ! Thanks.

Have you tried using cubic convolution resampling (on the display tab of the layer properties).

This does smoothing on the image so you don't see individual pixels.
