I am designing a map for a local trailhead kiosk that will show users where they are in relation to landmarks, others trails, hydro etc.  The scale of this map is about 1:15,000

 

I am working to generate some forests  using DEMs and Photoshop.   I've been playing around with this today and am generally happy with the results I've produced (attached gen.JPG).

 

I am a little unhappy with the way the higher elevation area are smooth.  These mountains are quite craggy and it would be cool to generate a representative texture for the alpine areas.  You can see the attached aerial.JPG which covers the same extent as my generated forest+hillshade image.   

 

Does anyone have any suggestions or examples for creating a good texture to use for these alpine areas?
 

Any other general thoughts on what I have created so far?

 

thanks in advance,

I've done a little more work on this map and am feeling better about the alpine areas.  I added some contours which help a lot.  Using some landcover data I created gradient masks in areas of the forest that are primarily sage/shrub or have more sparse trees.  Still a work in progress but I've been learning a lot about generating natural looking landcover.  Very fun stuff.  Now maybe some clouds or snow fields?

Just from you previous post I thought that was Sacagawea Peak in the Bridgers.  Then I saw Hardscrabble and knew I was right.  Just hiked it this past summer.

 

Don't have much to add about the map other then where is the loop trail from Fairy Lake, and make sure your streams follow your contour lines.

Excellent.. I was looking for the Patterson article.  Thanks for the link.  

 

Good eye Razornole!  The reason you cannot see the Fairy Lake trail is because I just shared a little snippet.  I will post a full map once I am a little further along.  

 

Thanks,

Thanks for the great suggestions.  I think I have the physical part of this map close to being finished.  Now to add features and some more labels.

Looking good!  The bump-mapped timber turned out well.  For the bumps, did you use a classified land cover image or just create a random noise layer+emboss+shadow?

 

Looking forward to seeing this at the trailhead!

Hey Brian!  I pulled out land cover classes from GAP, and then used those as masks for noise+layer+emobossing.

 

cheers,
