Good day folks,

I'm going through and finally getting my butt in gear and working on creating Painted Shaded Relief mapping and trying to get ideas for gradients to use in Adobe Photoshop. The design is based upon a 0 metre to 6,000 + metre range (sea to sky'ish)...

I understand that after a certain range such as the treeline and beyond, the colours begin to take a more mixed gray/brown schema and the likes below the treeline green and browns, but is there an excepted gradient used often?

Any input is appreciated

It depends how much detail you want to go into. I usually apply one gradient to my dtm (see the example above) and then modify the shading using regions of trees, proximity to water, roads and the like and relief shading of course.

If you like the colours in the maps I can dig out the colours I used on the ramps.

You might want to take a look at the Relief Shading and Shaded Relief websites - both have a lot of examples of relief shading to inform and inspire! Shaded Relief also has lots of information on cross-blended hypsometric tints - definately worth a look.

Hello DHissemGISCARTO,

I think what is acceptable in a color ramp is what works for you and your map audience. I personally like a color ramp that goes from tans to greens to yellows to browns to whites when going from sea/desert to snowy mountain tops. But that's just me.

There are some beautiful examples from the master, here:

I'd recommend Patterson's tutorials for Imhof's techniques, too. very often the colour scheme depends on the client's preferences, though.

You also got to take into account the 'rest' of the map, too. I.e. if you've got other map contents you have to make sure the relief is neither too strong opaquing other information nor too light to not been noticed.
If you are thinking of printing your map on paper (e.g. offset), you should be present at the print check to be sure colours come out exactly the way you want them (printers tend to put too much black and yellow ink on their presses).

HTH,
