    Link Texture shading and shaded relief material

    As I just posted in Francissimo's thread, I thought I put two links here. First one is an automated texture shading method to create relief shading enhanced with a "rocky" feel. The tool is tweakable so I advise you to make some tests first to get a hold on it. This is aimed at people who have a bit of GIS practice as you'll need to use floating-point raster as input and be careful with the data you'll use.

    An other link to a cool website probably already mentionned previously here because it's, according to me, a mut-see. It provides some really interesting tutorials mostly aimed on the creation of relief and its enhancement.

    great stuff, i hadn't seen the first site you linked. i've been driving myself crazy with shaded relief work lately - the grayscale heightmap is done, but every attempt i make to colour it gives me terrible results. no combination of layer styles seems to get it right. ah well, back to the drawing board...

    Thanks for sharing, the texture shading PDF is not only great for the content it contains, but is a GREAT example of the design process ---- Leland Brown outlines the issues, does a thorough audit and analysis of the situation and states his goals and objectives clearly and then goes about solving the problem. Anyone new to design should look at this for a great example of the process of design.

    Last year I added an implementation of texture shading into Wilbur as I described at https://cartographersguild.com/showthread.php?t=36031 (in case anyone wants to try it). It's a wee bit twitchy, but that's sort of the nature of the beast.

    Thank you for the link waldronate, I didn't know about this post. This is impressive work you made there!

    The Wilbur implementation has a number of features removed such as real-world coordinate systems (it's up to the operator to figure out relevant settings for map edges and shader parameters to get good results). If you haven't seen it, http://www.cartography.oregonstate.edu/ has a lot of interesting things on it as well.

    I love your 'twitchy' software Waldronate

    (even if I'm not very good at steering it yet!)

    gimp can also shade images

    this example was done in Gimp 2.9.4 from a 32 bit float height map and matching texture
    The planet -- TRAPPIST-1 / F



    now this i a rather low resolution ans full spherical map

    start with basic colors -- think watercolor painting , then add the details with a shade
