American States GIS Dataset
Update: The dataset is finished, and very pretty.
For a CS490 project I’m working on I need to colour a map of the US by continental state. Now, this is easy–except I needed a set of (x, y) points for each state’s boundaries–which is incredibly hard to find. There are GIS sets for every contour of the US at giant resolutions, but I couldn’t find a simple poly approximation of the states for graphic purposes. So, I’m hand drawing it. It’s not accurate–but it’s for a demographic demo, so it doesn’t need to be. Here’s a preview:
Still to do:
Finish adding the tiny eastern states- Merge points of intersection for uniformity
Import from {x1,y1, … , xn, yn} to {x1, x2, … , xn} and {y1, y2, … , yn} format.
When I finish the dataset, I will append it to this post. No one should have to cull US state boundary data again….
Update: I have imported it into matlab form, now. It’s still rough, and the points haven’t been merged, but good progress has been made. Check it out.
