Google Maps 8-bit for NES


For April 1st, Google has released Google Maps 8-bit for NES, along with the tongue-in-cheek promotional video above.

Check out the new style on the Google Maps page. There are some details (buildings, creatures) appearing when zoomed in.

Does it look better than this 8-bit map?


New map styles from Stamen Design

learnt today that Stamen Design have released new map styles for Open Street Map data. I really like the watercolor one, as it is quite different from what is usually seen on web maps. The other two are:

  • Toner: Very clean black & white
  • Terrain:  Features hill shading and natural vegetation colors

A Javascript API is provided in order to access the tiles. If you would like to roll your own maps (with TileMill, for example), the styling instructions are also available for Toner and Terrain.

Acoustic Cartography of Vancouver: Urban Sound Ecology

Urban Sound Ecology is a research initiative dedicated to exploring, examining, and understanding the sonic spaces of Canadian cities. At once an archive, database, and creative remapping of the city, Urban Sound Ecology is free to join and free to use. We invite interested participants to construct lines of inquiry into the aural landscape of Canadian cities by producing sequences of geo-referenced ‘soundwalks. (more)

Geospatial Revolution Episode 1

Very inspiring, especially the part on Ushahidi.

From the Geospatial Revolution project website:

The Geospatial Revolution Project is an integrated public service media and outreach initiative about the world of digital mapping and how it is changing the way we think, behave, and interact.

The mission of the Geospatial Revolution Project is to expand public knowledge about the history, applications, related privacy and legal issues, and the potential future of location-based technologies.

Geospatial information influences nearly everything. Seamless layers of satellites, surveillance, and location-based technologies create a worldwide geographic knowledge base vital to solving myriad social and environmental problems in the interconnected global community.

Go watch it! Next episode will be available on November 2.

OGC Table Joining Service

I have recently learned about an upcoming OGC standard that looks interesting: The Table Joining Service (formerly known as the Geographic Linkage Service or GLS). It standardizes a solution to the very common problem of mapping statistical data that is geographically related but maintained outside a GIS. To do that, the service uses a key (for example, a country or zip code) common to the statistical dataset and a geographic dataset providing the geometries.

The TJS has 2  kinds of operations:

  • Data access operations: They allow the straight retrieval of statistical data in a XML format called GDAS (Geographic Data Attribute Set). One operation also provides metadata that can be used to generate suitable symbolizations automatically.
  • Data joining operations: They allow the dynamic join of statistical and geographic datasets. A join query can also include SLD styling instructions. The output of the join operation is usually a custom WMS service that can be used to retrieve actual map images.

It is not yet an official standard (only a RFC has been published) but it should be adopted in the next few months.

There is already an implementation available (that was how I learned about it) in the Géoclip Server product. The publisher has a page with some more details on TJS, as well as a demo application (click on the icon at the top to access a TJS).
