Using Data

Census Data Acquisition from Boundary Files

On this site:


the author uses census boundary files to get coordinates of points that make up the boundary of a polygon.


When I tried to do the same thing with boundary files of block groups from the 2010 census for California. One of the files contents was in hex format and the block groups arrangement of polygon data isn't clear to me even after I converted it to decimal from hex.


I need help to do the same thing as in the article above except with 2010 block groups.
