QGIS techniques and tips: How to shade a map of categorical data
You will learn: How to shade a map from a table containing categorical data
Now, let's look at shading our map. There's three options in here.
Single Symbol: Shading the map all in the same color - really important if you're just doing simple map overlay.
Graduated: This is by far the most tricky of the three. It's a shading technique for numerical data. For data such as critter density or tons of fruit per hectare, or numbers of teenagers living in towns. How you go about dividing the data into classes will vary from project-to-project.
Categorized: As the name suggests, this is shading according to categories or names. This what we’ll be doing today - mapping Land Use categories such as Agriculture, Recreation and Urban uses. Aside from showing you how to map our Land Use categories I’ll also show you how to approach determining a Shading Scheme for your map.
In the video, I also suggest some starting points to finding a good color scheme for your map categories.
