In this lab, we explored ways to visualize terrain in our maps. We used contour lines in the first part of our assignment, and learned how to annotate our labels with a mask for a pleasing presentation of legible labels. Then we created hillshade effects, both traditional and multi-directional, and compared the results.
The exercises led to a better understanding of how hillshade worked, and I decided to use the multi-directional hillshade option for the assigned map of Yellowstone National Park. A landcover map, we layered the topology under a layer of symbolized classification types. These classifications mainly included types of vegetation, so I used a series of greens, browns, and oranges for the unique symbolization. The effect created a map with terrain "texture" to represent elevations. The resulting map image is below:
The multi-direction hillshade shows more detail for a more intuitive interpretation of the land, where as the traditional resulted in the symbology looking a bit dark in some areas. I did like that a few regions of elevation were emphasized for a more dramatic effect, but I chose the better option for the entire map versus pinpointing specific areas. For a different map or project objective, I would probably experiment between the two to see which one works better. The tool is quick, and the outputs really help to give map viewers a better visualization of the region's terrain.
I am noticing as I complete these assignments that the layouts are becoming quicker to organize, and I feel like design decisions are coming more naturally to me. I have background colors saved, visual hierarchy combined with proper color representation of features helps me to narrow down the best options, and a "personal style' is developing. This is a relief, because I have spent way too much time messing with the size, placement, and design of basic map elements.
