Small world: Electron Micrograph
The small world as seen through a scanning electron microscope.

The Photonics Research Group of Ghent University-IMEC has fabricated a world map on a scale of 1 trillionth. Using CMOS fabrication tools, IMEC has reduced the 40-thousand-kilometer circumference at the equator down to 40 micrometer, about half the width of a human hair. The map is put in a corner of a optical silicon chip designed for one of the group's research projects on nanophotonic integrated circuits. The scale reduction enables more complex optical functions on a single chip for applications in telecommunication, high-speed computing, biotechnology and health-care. Noteworthy, the factor of 1 trillion corresponds to the scale prefix Tera (like in Terabyte), but in this situation it would be better to call it ‘Terra’-scale.

An ancient story of conquest is heard again
By Monica Pratt

Lienzos are maps that tell the story of a place. The story of the Lienzo de Quauhquechollan, one of the oldest of these maps, is being told on the Web 500 years after the events it records occurred. A responsive and intuitive Web site developed by the Universidad Francisco Marroquín (UFM) and Geosistemas y Tecnología Avanzada, S.A. (Geosistec), ESRI's distributor in Guatemala, using the recently implemented ArcGIS API for Microsoft Silverlight, has made sharing this cartographic treasure with potentially millions around the world possible.

The Original Multimedia Experience

For the peoples of Mesoamerica, place and past were inseparable. Lienzos not only recorded the details of a geographic location but also communicated what happened there in a form of mapping now described as historical cartography. Graphic symbols designate people, places, and dates while stylized images of plants, animals, rivers, roads, and other features indicate where the story took place.

Lienzos were not meant to be studied silently by individuals but were performed aloud for groups by a narrator who brought to life the events shown on the map. The story was recited to audiences assembled at market days and other community gatherings.

A Uniquely Important Map

Dating from circa 1530 to 1540, the Lienzo de Quauhquechollan tells a story of great adventure—the Spanish conquest of Guatemala. It is an important historical document for many reasons. Not only is it the first known map of Guatemala, but it also provides the only firsthand account by indigenous people of this military campaign.

This account changed previously held beliefs about the conquest of Guatemala. The lienzo illustrates how the Quauhquecholteca of central Mexico, who viewed the arrival of the Spanish conquistador Jorge de Alvarado as an opportunity for enhancing their own power base, allied with his forces to conquer Guatemala.

The Quauhquecholtecan artists recorded this triumph on 15 rectangular pieces of cloth. Together, these panels show selected elements, both events and locations, that these artists felt would help listeners best experience the story. The existing map is 10 feet, 6 inches wide by 8 feet, 5 inches long. However, the lienzo did not survive intact. A portion of the right side of the lienzo—perhaps as much as one-third of the original—was cut off. [...]

Google & Audi take Google services in a car to the next level in the new Audi A8

If Google was a car, what kind of car would it be?

Nowadays, it seems like everything is connected to the Internet: mobile phones, laptops, netbooks, portable game consoles, personal navigation devices. Think of how applications such as Google Maps for mobile have changed the way you find locally relevant businesses or addresses, or real-time traffic along your route. We can even get online from 35,000 feet while on an airplane, or while traveling at 300 km/h on a train. Google has worked with the automotive industry to bring services like Local Search into cars in the past - now we're teaming up with Audi to bring an entirely new type of technology into the car: Google Earth.



With their newly unveiled Audi A8, Audi is the first car manufacturer to bring Google Earth directly into the vehicle and to combine that with a set of useful Google services. We've worked closely with them to create a compelling in-car experience integrated with the Audi navigation system. You'll be able to enjoy 3D satellite imagery, terrain information and a wealth of additional geo information relevant to your current location: layers like Wikipedia to learn more about your surroundings or Panoramio images to get another view.

To help you figure out where you want to go and how to get there, we've also brought Google Maps and Local Search into the A8, and linking it to your desk. You can send business listings directly from
Google Maps to your car: search for an address at your desk, send it to the car, and by the time you go to the parking lot your car will know where to go. While in the car, you can use Google Local Search in the same rich quality as at your desk. Imagine you get hungry on the way or want to find a cinema – simply perform a live Google search on your car navigation system and immediately get up-to-date, rich and relevant results.

Google Earth has come a long way from when it received "oohs" and "aahs" during its demonstration for Googlers and the public in 2005: it has now been downloaded over 500 million times on the desktop, is available in 41 languages, and has a mobile version for iPhone. As Germans, with a natural born passion for cars, we're very excited about this newest milestone and we hope that drivers will have that same "ooh" and "aah" reaction when exploring Google Earth from the Audi A8.

Our mission to organize the world's information and make it universally accessible and useful is paid into by the efforts of Google's automotive team - they always are trying to find new ways to make relevant information accessible and useful - now also in your car.


Herzlich willkommen, Audi!

Get JavaScript Access to Google’s Flash Maps API


Google Flash ...

Flash the Google map ... Will we ever see a SilverLight API for GM ;-) ?

Adam DuVander

When you want animated maps or zippier feedback than Google’s JavaScript mapping API can provide, you can use the Flash Maps API. Yes, even Google acknowledges that its popular, full-featured platform can’t do everything. Using the Flash API used to mean you needed to know Flash. Now, you can get the benefit, but still program in JavaScript.

Web developer Nianwei Liu has released a wrapper API for Flash Maps, called Map Bridge:

“The concept is very simple: programing a flash component with JavaScript, similar to what you do with GStreetViewPanorama. This library exposes all core classes in the Flash API and packages them in an easy to use way.”

The code then becomes quite similar to the standard Google Maps API, as well as other mapping platforms. A map is attached to a DOM element via JavaScript. An included library takes over to insert the map in its place, only instead of loading tiles via JavaScript, it calls Flash functions.

JavaScript Flash Maps

An example within the announcement post shows driving directions with an animated fly-over. Like Liu’s mention of Street View, this shows why Flash can be useful for mapping. Even the geniuses that originally created Google Maps can’t get an experience as smooth as what Flash provides.

The highly technical and curious will appreciate that Map Bridge is open sourced. Like other mapping wrapper APIs, such as Mapstraction, you can alter and contribute to the codebase. Or, just find out how it works. Perhaps other API providers will learn from Map Bridge, making Flash APIs accessible to more developers by including JavaScript wrappers. [...]

In this paper we present novel input devices that combine the standard capabilities of a computer mouse with multi-touch sensing. Our goal is to enrich traditional pointer-based desktop interactions with touch and gestures. To chart the design space, we present five different multi-touch mouse implementations. Each explores a different touch sensing strategy, which leads to differing form-factors and hence interactive possibilities. In addition to the detailed description of hardware and software implementa-tions of our prototypes, we discuss the relative strengths, limitations and affordances of these novel input devices as informed by the results of a preliminary user study.

Clever folds in a globe give new perspectives on Earth

A new technique for unpeeling the Earth's skin and displaying it on a flat surface provides a fresh perspective on geography, making it possible to create maps that string out the continents for easy comparison, or lump together the world's oceans into one huge mass of water surrounded by coastlines.

See a gallery of the new maps

"Myriahedral projection" was developed by Jack van Wijk, a computer scientist at the Eindhoven University of Technology in the Netherlands.

"The basic idea is surprisingly simple," says van Wijk. His algorithms divide the globe's surface into small polygons that are unfolded into a flat map, just as a cube can be unfolded into six squares.

Cartographers have tried this trick before; van Wijk's innovation is to up the number of polygons from just a few to thousands. He has coined the word "myriahedral" to describe it, a combination of "myriad" with "polyhedron", the name for polygonal 3D shapes. [...]

Google Releases Fusion Tables API for Visualizing and Sharing Data

Google has released a new API for Fusion Tables, a Google Labs app that allows users to import, integrate, analyze, and visualize data in a variety of ways. The new API allows developers to programmatically perform a variety of tasks, including data import and export (more at our Google Fusion Tables API Profile). The API itself is integrated with several other Google APIs, including the Google Maps API and the Google Visualization API. In fact, developers can also leverage App Engine to easily develop data processing and analysis apps that easily integrate with various other Google APIs.

google-fusion

The new API was announced on the Google Code Blog, which provides some additional insight into some of the benefits of the API:

Is your dataset active, always changing? Is it being collected right now on cell phones or websites? With the new Fusion Tables API, you can update and query your dataset in Fusion Tables programmatically, without ever logging in to the Fusion Tables website. The API means you can import data from whatever data source you may have, whether a text file or a full-powered data base. On the more exotic side, imagine you’re collecting data via survey software on GPS-enabled cell phones, as the Open Data Kit project is doing. Open Data Kit uses Google App Engine and the Fusion Tables API to instantly map locations of survey results.

The RESTful API supports both GET and POST requests, and currently it is limited to 5 requests per second. A subset of SQL is used to query and retrieve data, insert new data, update existing data, and delete data. Google has made various resources available for developers includingreference documentation, tutorials, a FAQ page, tutorials, a code sample (Java), and a Google Group. Note that authentication is needed in order to access both public and private tables. [...]
