Purple Things?

[DFNewb]

I am just wondering but what are the purple things on the map?

Thank you

the splotches are crops, the teeny tiny dots are mostly trees, the large blobs are desert/swamp/forests the blue mass is water

How can you tell which one is what crop?

You would have to travel out to it. That map is a little old though, so some of those crops on it may not be there anymore.
