Hello all! <br><br>I have been exploring the best way to make a shaded relief map with color gradient. Although I have been using GIS for many years, this is a new topic for me. (New is always fun, especially with GRASS!)
<br><br>I have several questions relating to this topic.<br><br>1) I have used r.color to change the color gradient for the DEM I am using. There are a lot of nice palettes to use! One that I am looking for is a tan to green gradient (tan=high elev, green=low). There are some nice ones that are close, but is there a way to create a new color map going from color #1 to color #2? In the mean time, the red to yellow to blue is working well.
<br><br>2) r.shaded.relief creates some nice outputs! very cool. I have a ryb color map for the DEM, and have created a shaded relief map that is grayscale. Is there a way to make a color shaded relief map? I have been looking for examples illustrating the tools to use in GRASS that will do this. I found
r.blend, and it seems to produce something very close, if not exactly what I am looking for with more tuning of parameters. Is this the best combination of tools to use? --> r.color on DEM + r.shaded.relief + r.blend = color ramped shaded relief map?
<br><br>3) I have done a fair amount of researching the web for color shaded relief maps, but was unable to find techniques relating to GRASS production of these datasets, or a gallery of shaded relief maps produced by GRASS. Does anyone know of such a link?
<br><br>Thanks<br>Mark<br>
