RADICAL CARTOGRAPHY showcases couple of really nice examples. My two favourites: Mississippi meanders Statistical Atlas of 1870 US Census
Eduard Imhof's work, especially his hand-drawn hillshading maps:
As the question does not specify that a map has to be a traditional static map, I would like to propose the Mapnificent London travel times map. As per usualy, Google are really pushing what you can do with Online Mapping APIs. In terms of map design, the v3 API now gives you greater control over tweaking the underlying base map. The map is also very ...
I do not know ArcPy, but I work with shapefiles and raster in Python for years For processing shapefiles in Python, there are many modules like osgeo/ogr, Fiona, Pysal or Pyshp (shpUtils is one of them and not the most used), and others, see Pypi: GIS and examples on gis.stackexchange and many examples on the Web (not only in English). Most of them are ...

Try "QuickWKT" plugin. You have to allow experimental plugins to be able to install it.
Originally created and posted by Tear on the Cartographer's Guild Forum. A hand created map of George R. R. Martin's Westeros from The Song of Ice and Fire series:
Reykjavík Interactive Map
This is the one that started it all for me. At age ~10 I first read R.L. Stevenson's Treasure Island. The map somehow encapsulates the mystery, adventure, search and discovery of a great story. Not only that, but Pirates! Har.
U.S. National Park Service Maps (from Getting Real: Reflecting on the New Look of National Park Service Maps):
I played with this topic a lot some time ago. You can find some examples here: Dobrou extensions plugin examples Dobrou extensions plugin homepage Using Sporttracks and this plugin, gps tracks can be converted to KML and displayed in Google Earth. It supports some ideas mentioned here - track coloring based on color gradient, direction arrows and much more. ...
Here is a good one: The Atlas of Canada Map of the North Circumpolar Region http://atlas.nrcan.gc.ca/site/english/dataservices/wall_maps/MCR1-2.jpg/image_view Also interesting is the Cartographica journal article describing the work involved in putting this map together: http://utpjournals.metapress.com/content/d80604507k247v46/
I like interactive maps from Stamen a lot. Especially, for their their focus on handling temporal interaction. Examples: SF crimespotting Hurricane Tracker (Update) Surging seas A non temporal example: Watermark, Terrain and Toner tiles
I've always done it as width. For example you create a buffer around each point that represents speed and then dissolve the buffers into one. Narrow areas indicate bottlenecks. For an example see: http://www.fmepedia.com/index.php/Bufferer Of course, you can even color code the buffers before merging them. For an example see: ...
My favourite maps are John Ogilby strip maps of routes within Britain. The originals are from 1675, though there was also an official reprint around 1700 I think. I have this one (the road from Hereford to Leicester) hanging in my office. I'd love to get a full atlas, but the cost would be rather more than I can afford! Truly beautiful, not to mention ...
This video should give you a general idea of how to create nice line styles in QGIS with new symbology: "Video tutorial #1: Creating a custom railway style" More related posts: "Vector rule editor and polygon line styles in QGIS" "Advanced Layer Styles in QGIS" In Tomtom data for example, you have an attribute called frc that can be used to classify ...
Can't believe no-one has mentioned XKCD's Map of the Internet: and this one has some mind-blowing aspects:
Good question. Geography, and later GISc have been struggling to incorporate 4th dimension since Torsten Hägerstrand brought time into geographic research. Couple of things from the top of my head: One of the solutions is to use 'space time aquarium' where in 3D space you can use X and Y to represent location in space and Y to represent time. Two names ...
This is pretty much an interactive map This is a truly wonderful thread for a maplover like me! I found this (with a little help from my friends) Rock and roll. Metal Map
As always, it depends on your objectives and the nature of the data. For completely mapped data, a powerful tool is Ripley's L function, a close relative of Ripley's K function. Lots of software can compute this. ArcGIS might do it by now; I haven't checked. CrimeStat does it. So do GeoDa and R. An example of its use, with associated maps, appears in ...
From 2011 SND awards: Best printed map -NG ‘Gulf of Mexico’ map (PDF available here): Miguel Urabayen Award - NG ‘World of Rivers' map: (Interactive version here) (Via FlowingData blog)
The problem is to figure out how much to bend the arcs to enhance their visual resolution. Here's one solution (among the many possible). Let's consider all the arcs emanating from a common origin. The arcs get most crowded here. To separate them the best, let's arrange it so they spread out in equally-spaced angles. It's a problem if we draw straight ...
Creating great circles could give you the desired effect. Maybe something like discussed on http://lists.osgeo.org/pipermail/postgis-users/2008-February/018620.html Update: I've followed up on this idea in "Visualizing Global Connections". It's a purely PostGIS-based solution using reprojection to create arcs. SELECT ST_Transform( ST_Segmentize( ...
A simple and efficient way is to color the segments depending on their speed. For example, "fast" segments can be displayed in green and "slow" segments in red (other colors can be chosen of course). Example on an orienteering-running GPS trace using the software Chmuk: Another example with the software quickroute: The parts of the route where the ...
From the hip my answer would be Stephen Walter's 'The island': witty, irreverent, slightly subversive he has hand drawn a map of London representing it as an island (poking fun at Londoners' London centric view of the world). http://www.bl.uk/magnificentmaps/map4.html I think its beautiful as its highly original, detailed, fascinating and I interpret it ...
The INSPIRE data specifications define some standard styles for portrayal of topographic data (transport network, hydrography, administrative units, etc.). See for example the section "11.Portrayal" of this document for hydrography. If you are looking for standards for the representation of style, see SLD and GSS.
Shanghai Interactive Map: Actually there are many other cities there drawn in such style. Use google translate ;) Very interesting renderer, quite good for interactive public maps I think.
I would say you can't include all that data on one map and have it make any sense. I'd recommend you think along the lines of Tufte's principle of small multiples, having multiple smaller maps of the same area, each using a different variable. Example: http://www.juiceanalytics.com/writing/better-know-visualization-small-multiples/ Even then, you have ...
Many beauties on BIG map blog. For instance, Birdseye map of Coronado, San Diego by a property developer, 1880s: (via O'Reilly radar)
I love Dymaxion maps. In this example from Wikipedia, it used to map human migrations: Reminds me again of how tiny Europe is.
