Thought I would post a few samples of a texture I have been working on. Its a work in progress. Comments welcome.

It's looking quite nice. What program are you using?

[burwelbo]

The initial hilshade was done in ERMapper but the texturese were all created in ArcMap using Spatial Analyst. Here is a better screen shot of the textures.

Looks good:) Is it for print or for on-screen use? Color contrast could be higher in my opinion if for on-screen use (my personal preference).

[burwelbo]

This one was going to be for print but I was hoping to make a serious of them for on screen display. Thanks for the input.

Looks like you're working with Canadian federal data, in the BC Kootenays area. I immediately recognized the pink built-up area as my hometown of Nelson. Nice to see all the familiar mountain ranges from this perspective! Are you going to tell us more about use? What's the theme for the print map, etc?

Its for a backcountry ski map.

Nice Bump Mapping! I have seen similar Spatial Analyst-based textures a la Jeffery Nighbert.

Have you seen the methodology discussed in this article? I am wondering if you are using a similar methodology.

How many types of features are you bumping? I can see two different "bumps" - a green one and dun-colored one (maybe conifer/deciduous?).

In your close-up there is a semi-transparent green line (boundary?) near the top and I am wondering if that linework would look better above the hillshading, but below the bumpshading. Regardless, this looks really good!

For this project I used the new bump mapping toolbox to create a coniferous, deciduous and shrub class. The pattern was based on a land cover classification. I then stacked them in Arcmap using different transparencies. Thanks for the comments.

bump mapping toolbox... are you on ArcGIS 10... ?

[burwelbo]

I have the pre-release of 10 but it also works in 9.3.1.

[Charles Syrett]

For those of us who use tools other than Arc, Tom Patterson has had (for some years now) some excellent tutorials on bump mapping on his website.

You can get the bump toolbox from the Mapping Center Resources page. In addition tho the link in my previous post, I found another post from ESRI regarding the tools. In addition you can also brush-up on the technique with the ESRI Mapping Center article titled Symbolizing the Bump Map.
