Looks like a local coordinate system, probably something based on the Texas 
State plane coordinate system (if it exists).

I've got shapefiles from the state of Texas describing their new political 
districts. It's the first shapefile I've seen where the coordinates don't seem 
to be in lon/lat; rather, they look like this: 

[1413007.7300121039, 1159556.348466374], [1413007.6640587151, 
1159558.0074478425], [1413007.5669405311, 1159560.4406569004].... 



Anyone know of the top of their head what the units are here, and how I map 
them to lon/lat? 



Below is the accompanying DBF. Thanks in advance!
