Hi,

I am working on a project and basically, I'm trying to import a map of US with the counties marked on it. my purpose is to add data about each county, specifically about the concentration of different ethnicities. Then, I want to give each county a certain shade of color based on the concentration.

Does Matlab have a feature which can detect the counties on a map? if so, can each element (county) store data and be assigned individual colors?

I am experienced in Matlab and have coded a lot of numerical analysis projects before. This is a side project, and I've never worked with image importing and detection in Matlab, which is why I'm asking.

Thank You
