Part 4 of my 4 part presentation to the WAURISA GIS conference, held in Lynnwood, WA May 2013. In this section, I look at taking what we've learned about layer masks in Photoshop and apply it to Illustrator. We'll use masks to create an easy way to transition contour colors over various land cover types, and we'll use masks to add character to otherwise perfect vector linework and fills.
