I'm not a GIS professional, it's just that my current project is heavily reliant on geospatial data.
I'm currently working on a project that has to do with transportation behavior. My hypothesis is that the specific behavior I'm interested in has a regional component to it. For example, agents moving through New York might display this behavior more heavily than agents moving through Texas.
What I'd like to do is have the United States partitioned into uniform clusters (imagine if the states were all the same size) such that for any given transportation route that an agent takes, I can track the clusters that it travels through. This linepath can then be used as input into my main model of interest.
I had considered Zip Codes, as they appear to be roughly uniform, but I have a fear that they are too small/too granular for my purposes. Zip Code Regions have the opposite problem: they are too big.
One other constraint I have is that I work with latitudes and longitudes exclusively. So if a system exists that can take a (lat,long) pair and map that to a cluster, that would be the most ideal solution.
