While rendering the new slope shading layers, I also rendered data tiles for elevation, slope and aspect. CalTopo can now use these to create custom shading for the continental US. Want to color all north facing aspects above 7000′ and steeper than 32 degrees blue? Create an elevation relief map? No problem. Unfortunately I haven’t had time to create a slick UI, so the purpose of this blog post is to serve as documentation.
|Slopes between 15 and 30 degrees shaded red, as per the first line|
|North facing slopes above 7k and 32 degrees or steeper|
|Mountains around Squaw Valley, CA shaded using the above gradients|
|A high level view of terrain 25 degrees and steeper in the Pacific Northwest.|
