yellow-blue Swiss Hillshade with TerrainTools?

[andreamilan]

Hello to all,

I found it very interesting this paper :

http://cartography.oregonstate.edu/pdf/2006_JennyHurni_SwissStyleShading.pdf

the same is reported here Cartography and Geovisualization Group, Oregon State University

the results that they have achieved based on colour reference points and a look-up table is what I’ve always tried to get but I read that this process has been Implemented in a application prototype and I do not find this application in any software.

I tried   with Terrain Tools for arcgis 10.3  , in documentation  I read that “Tools Swiss Hillshade”

guilds and then combines several hillshades to give a yellow-blue Resulting Swiss hillshade effect “,it would seem a solution  but what I get is just one Swiss_Filtered grayscale and one Swiss_Hillshade grayscale, no blue yellow hue. You know tell me where I’m wrong?

I would like to get a final result like this:

but perhaps also because of my very simple English very simple, I can not find online articles, books or instructions that describe how to reproduce this effect digitally. I will be very grateful if you could give me some guidance

thanks Andrea

I can't get the last link to work..

In any event, http://www.arcgis.com/home/item.html?id=4b2ea7c5f87d476a8849c804b81667aa  is an incredibly large download to do testing with, however, they indicate that it has extensive documentation.  It does say that it just produces and combines the hillshades, perhaps the hillshade result needs to be combined with the symbolized dem to produce the result you want.  Check your documentation and see this link (for the spatial analyst, but the same for 3D http://desktop.arcgis.com/en/arcmap/latest/tools/spatial-analyst-toolbox/how-hillshade-works.htm

thank you very much , I've read the documentation attached to terraintools (TerrainToolsDocumentation.pdf). About how to combine the layers to get the yellow blue effect it remains a bit vague to my knowledge, it says: "the three resulting rasters - the filtered hillshade, the aerial perspective hillshade, and a copy of the original DEM are rendered with different transparencies and a blue to yellow colour ramp and placed in a Group Layer to produce the final Swiss-style hillshade."

My question is simply.

I do not understand how I have applied color blue / yellow to these three layers and if I have to combine them with a Tynt hypsometric in order to get a picture like this:

The yellow blue color, according to the principle of Imhof, it should be calculated by the combination bye elevation and exposition parameters but the documentation does not describe how to apply this step, or maybe the passage has escaped me.

This is the first step that I'm still trying to understand how to obtain, after I suppose this layer group will be superimposed on a layer that will indicate the ground color (green, brown, etc.)
