  • You can download SF 1 Census data, with all the states compiled into a single geodatabase, from a relatively new “blog + extras” site called They get bonus points for the GIS quips in the upper-right corner of the homepage: 

  • If anyone needs a continental U.S. polygon representing the landward borders and a 5 nautical mile buffer extending seaward from the coastlines, let me know. Created today out of several datasets.

I find the polygon tools like advanced merge (where you can intersect datasets in several useful ways) and fill holes very instrumental in getting data creation tasks completed. You can do everything with the free version as long as the input datasets have less than 100 features.
