I just solved a problem exactly like this with the United States' 2012 Census Block Groups. I used ArcGIS to breakdown the borders to their individual line segments (in other words each line that consists of only two vertices), and captured the line length of each segment of each area. I then transformed the lines into midpoints and did an intersect analysis....

The link below is to the National Geospatial Agency (NGA) Geographic Name Server (GNS) for geographic features of Austrialia. The dataset has been converted to a linked CSV format and should be easy to parse. Your interest will be in records that are administrative divisions (NGA/GNS FCFC=A). The value of NGA/GNS DSG will tell you the type of administrative ...

In accordance with the inimitable "logic" of the Census website, the files in question are not located with the other block assignment files. Rather they are on a "113th & 114th Congressional and 2012 & 2014 State Legislative District Plans" page under "Redistricting Data". Even on this page, do not be fooled into thinking that the section labeled "...

Jeffrey Lewis has compiled a complete set of geoJSON files for every congressional district through all of time. You should be able to use that to pretty easily figure out adjoining districts. Here's the link to the GitHub repo.

For example my city shares a zipcode with another town (same county). It shares a school district with a completely different town, in a different county. The high school also hosts some classes for another town, that is in ...

The GADM database of Global Administrative Areas could be a good place to start.

GeoNames does indeed provide the relationship between parts of cities and their postal codes. A few examples: Parts of London with the postal code EC1 Postal codes of districts in Austria called Innere Stadt (Inner City) You can either use GeoNames' Postal Codes Lookup Tool, or you can download the database dumps in text format for many countries. The ...

The resource I use for conversion of one weird U.S. geography to another is Missouri Census Data Center. In particular, they have the 113th Congress, but miss the 112th Congress. You can ask them why if you are sufficiently curious :).

on the fly solution: This map of North Carolina Trial Courts provides links to county pages that have the judicial district number. I would write a quick script to crawl that and get jd number linked to a county name. Then in the Google Civic API, after making a call, you can pull out the county name of said call response, and match to that. EDIT: Here's ...
