Adventures In Mapping

Here is a step-by-step if you are interested in how the felt is made (here’s the whole map-making-madness channel, if you are feeling brave). It covers the creation of a texture in Adobe Illustrator, using that texture image in Pro symbology, then saving and using a saved style. Also, you get to hear my nasally Midwestern … Continue reading How to Make the Felt Style

Slightly different than a flattened single-band multidirectional method and way different than an aspect map. If you are interested in how do to it … Continue reading Throwing Shade: Gallery

Here are some examples of using selective hillshading styles based on a Glaciers masking layer. Glacial hillshade is icy and non-glacial hillshade is earthy. Here’s a how-to. Southern Andes… Southern Greenland… Alaska Range… Alps… Caucasus… Western Himalayas… Here’s a shoddy video if you are inclined to give it a go… Continue reading Selective Hillshading
