Eduard Imhof’s Schweizerischer Mittelschulatlas is probably the best example of applied beautiful cartography ever. Codex99 has a very good presentation of him and his work here: Imhof wie ein Kartographische Rockstar

UPDATE The new files are now available and known as "Cartographic Boundary Files". More detail on the other types here http://www.census.gov/geo/maps-data/data/tiger.html The County file discussed above is available here: http://www.census.gov/geo/maps-data/data/cbf/cbf_counties.html The official file is not currently available as of 5-12-2011, but ...

In ArcGIS 10.1 you can use the Geometry on Geometry Check Tool and use the 'Spatial Relation Check Touches' Touches—A part of the feature from feature class 1 comes into contact with the boundary of a feature from feature class 2. The interiors of the features do not intersect. ...

For Germany, Austria and Switzerland and other European countries, you can find the data from the Eurostat (different levels of NUTS). Those are the "official ones". You have 1 294 entities at level 3.

You could find a topological representation of county boundaries, such as the CTA boundary files (another source would be the OpenStreetMap, but that's not as complete) and then pick out all distinct pairs of county IDs on opposing sides of boundary lines - e.g. in the CTA files, there's these two fields in the link entity (as described in the ...

I don't think BLS unemployment data is available by ZIP. The MelissaData source does not actually report unemployment by ZIP code, it tells you the unemployment of the county in which the entered ZIP code is located. For example, a search for 02451, a small ZIP code in Waltham, MA (population 60k) returns 826k people in the labor force. This number must be ...

The easiest way would probably be to use a layer with the city boundary of San Diego. You can obtain this from the SanGIS (San Diego Geographic Information Source) website. Use the boundary layer and do a spatial selection for any census tracts that have their centroid within the city limits. Another option would be to go to the Census.gov website and ...

Since you mention you are a programmer, here's some code that works with arcgis 10. Update: If you don't feel like programming, I've posted a zipped shapefile of the graph here. public void TestGetNeighbors() { var fLayer = ArcMap.Document.FocusMap.get_Layer(0) as IFeatureLayer; var dict = GetNeighborsByName((ITopologyClass)fLayer.FeatureClass, "{0} ...

UPDATE: Added spatial index to improve performance and brief instructions for using this script on Windows. #------------------------------------------------------------------------------- # This script will build an adjacency table in csv format representing # county polygons that "neighbor" each other. This script is intended # to illustrate the use ...

I would look carefully at the data sources listed in The Spirit Level. The authors of this book (who are epidemiologists by training) analyze state and county level socio-economic data for the USA, and compare it to socio-economic data for a selection of OECD countries (23 to be precise). They provide a download link for the data (which requires a form to be ...

Orienteering maps are good example of high scale maps. Very small features are represented on such maps, with a very detailed representation. The way to make such maps is rather well formalised in this document.

The GADM boundaries are pretty good, however you'd probably want to review them on a country-by-country basis. GADM is agnostic about what the administrative units are called, just referring to them as administrative levels one through N. If your goal is to get roughly 2,500 km^2 units, just divide each country's total area by counts at the different ...

Regarding the correlation between zips and counties. The zip code boundaries are generally stable, assuming the post office doesn't close a ton of offices like some people think they need to do. The big problem is that many zip code areas cross political boundaries. Some small cities can be entirely within a larger zip code. While it is possible to match ...

I am not sure how you are going to know or check the shoreline clipped aspect of your question. Esri has some datasets that are described as detailed (dtl). However you would need to aquire the Data Distribution Application (DDA) [see page 8 of the pdf] to get them into shapefile as they originate as *.sdc format. Data is provided in Esri’s compressed, ...

The US Census Bureau publishes tons of spatial maps. One of these that is interesting is the "Counties and Equivalents". These can be downloaded here: http://www.census.gov/cgi-bin/geo/shapefiles2010/main Once you have that, there is a shapefile importer for SQL Server here: ...

You can use the YQL console to find all kinds of concordance for a given WOEID, eg. for Austria the query is 'select * from geo.concordance where namespace="woeid" and text="23424750"', try the following link and click the 'TEST' button. ...

You can go the other way with /concordance/fips/{id} according to http://developer.yahoo.com/geo/geoplanet/guide/api-reference.html#api-concordance. Whether this helps probably depends on how many fips labelled objects you have.
