Post-Election Maps

Like many of you, we have have been enjoying some of the latest election maps in the wake of last weeks election results.  We thought we would share a few, in case you haven’t seen them yet.

The New York Times once again has created a number of excellent post-election static and interactive maps, their election results maps allow you to investigate results to the county level, and to view the shift in party voting by county compared to the last four elections.

The Digital Scholarship lab at the University of Richmond has created “Voting America: United States Politics, 1840-2008” which contains a terrific collection of map animations and interactive mapping applications for every presidential election since 1840.

Mark Newman, a professor of physics at the University of Michigan, has converted the traditional red/blue maps into cartograms – distorting the areas of states and counties to reflect the relative population.

Want to create your own election maps?  EDS can help you get started with United States Presidential Election Results for recent elections in Datagate,  and various boundary files that can be downloaded through our Spatial Data Catalog.

Google Maps NYC Transit

For those of you have not seen it yet – this week Google has added New York city transit data to Google Maps, allowing route planning on public transit.

You can plan routes on NYC Transit, LIRR, the Metro-North, the Staten Island Ferry and Long Island Buses.  The interface is intuitive and admittedly pretty fast, but routing options don’t seem to be as robust as some other products (like Hopstop), particularly finding alternate routes.

Water Watch

Eye on Earth Water Watch is a new interactive map viewer which is part of a five year partnership by The European Environmental Agency (EEA) and Microsoft. It includes more than 21,000 bathing sites across Europe, each site given a rating by both the EEA and by users.

The EEA water quality ratings come from the 1990 – 2007 coastal  and inland water quality analysis carried out by the European Commission.

It’s great to see the display of which years are included in the EEA rating when clicking on a site along side the number of user ratings, and a section for user comments.

Although I do like this site, it’s nice to see the datasets used are available for download so someone could potentially do other types of analysis. There’s also a data viewer and map viewer for looking at the data in a different way.

Meiji era Kantō region web map

Historical Agricultural Environment Search System (rough translation of 歴史的農業環境閲覧システム)

For those of you who are interested, there is a new web mapping service up showing seamless georeferenced maps of the Kantō region in Japan during the early to mid Meiji era. Overlayed on top of this are current road, river, and land use to view change. And as a added plus, a KMZ file is also available to view the full Meiji era maps in Google Earth,which ran a little slow when I tried it but was worth the wait.

Although the site is entirely in Japanese, it’s still easy enough to navigate around if you can’t read the characters.

Either choosing a location from the right hand side or just clicking on one of the places (marked by red circles) on the map opens up the mapping application – all the components are open source. If you overlay the 1997 land use data (it’s a little coarse compared to the 1880 data) you can see some of the changes.

The legend for the 1997 land use data on the map is in the FAQ – here’s a rough translation.

Left column – rice field (水田), other agriculture (その地農用地), forest (森林),  waste or unused land (荒地), built up area (建物用地)

Right column – transportation (幹線交通用地), other land (その地の用地), water bodies (河川および湖沼), beach (海浜), golf course (ゴルフ場)

If anyone has a better translation let me know and I’ll update the English categories.

Ride the City

Looking for a safe route for a bike ride through New York City? Ride the City helps find the safest bike route between two points by either entering in address locations or by placing points on a map. Emphasis is places on use of bike lanes and greenways and excludes roads not meant for bikes at all.

The base data mostly comes from the NYC Dept. of City Planning DCPLION Street data, the base map comes from Google Maps, and OpenLayers is used for the markers, vector lines, and pop-ups. More info on what was used can be found in the Ride the City FAQ.
