Impact Factor for International Journal of Digital Earth breaks 2.0

IJDE_Normal-2013 NEW-800

IJDE Impact Factor gets increase to 2.056

The Impact Factor of the International Journal of Digital Earth (IJDE) has been increased for 2013.

According to the annual Journal Citation Report by Thomson Reuters on 30 July, the new IJDE Impact Factor (IF) for 2013 had broken 2.0, climbing to 2.056 (2-Year IF) and 2.242 (5-Year IF). Its rank rose to 10th and 8th accordingly in the list of 27 SCI-indexed international journals in the Remote Sensing category.

Inaugurated in March 2008, IJDE was accepted for coverage in SCI-Expanded within 18 months of its launching. Currently IJDE has been indexed and abstracted in 12 databases, and entered the Q2 area in the Remote Sensing Category based on its Impact Factor.

The growing prestige of IJDE is attributed to the high-quality and high-level of published papers and the accompanying high citations. The journal’s increasing growth is also the result of the rapid development of Digital Earth science and technology, the joint efforts of researchers, and the strong support from ISDE and the host institute RADI.

As a unique journal on Digital Earth, IJDE focuses on the theories, technologies, applications, and societal implications of Digital Earth and those visionary concepts that will enable a modeled virtual world. We expect more high-quality papers related to digital earth published on IJDE and look forward to your continuous contribution and support in the future.

Digital Earth is the name given to a concept used for “describing a virtual representation of the Earth that is geo-referenced and connected to the world’s digital knowledge archives”. A very large amount of data is produced to represent multiple facets of our planet. As a result of continuous developments and massive use of new information and communication technologies, there is a considerable increase in sources of geo-referenced data. In recent years, new scientific and technological advances in the fields of sensors networks, remote sensing systems, spatial data infrastructures, Web technologies and volunteer geographical systems have increased the availability of spatial information at different geographical scales. Advances in computing have also enabled scientists to develop complex models for simulating earth phenomena (e.g. global climate change) that produce a huge volume of data. All these information require effective storage methods, as well as designing effective integration and processing techniques. New database technologies must be invented to better represent the complexity of spatial data (e.g., uncertainty; complex structures), to guarantee the quality of integrated data and to process the huge amount of information available (e.g. use of spatial data warehouses; non-relational databases; processing of raster databases or continuous fields).

The purpose of this special issue is to present the latest advances in the field of spatial databases for digital earth (focusing on data storage, integration and processing). Various application areas can be presented (earth observation, geosciences, environment, agriculture, natural hazards, etc.). The main topics of the special issue will be:

  • Databases for storing data produced from remote sensing systems
  • Storage of data collected by sensors networks
  • Spatial data query and aggregations in large infrastructures (relational databases, No SQL, etc.)
  • Continuous fields and raster databases: representation, map algebra and performance issues
  • Spatial data integration and Extraction-Transformation-Loading tools
  • Efficient storage, integration and processing of volunteered geographic information
  • Spatial data warehouses and Online Analytical Processing tools
  • New spatial data standards and infrastructures
  • Spatial data quality management and integrity constraints
  • Spatial “big data”
  • Spatial data storage in cloud computing
  • Spatial databases of simulation results
  • Digital earth data and ontologies
  • Spatial data mining in digital earth data
  • New conceptual, logical and physical spatial data representations
  • New models for representing uncertain spatial data
  • etc.

The paper submission deadline is September 30th, 2014.

Authors will submit their manuscripts on-line

TIMELAPSE Project: “Time and Space”


Spacecraft and telescopes are not built by people interested in what’s going on at home. Rockets fly in one direction: up. Telescopes point in one direction: out. Of all the cosmic bodies studied in the long history of astronomy and space travel, the one that got the least attention was the one that ought to matter most to us Earth.

That changed when NASA created the Landsat program, a series of satellites that would perpetually orbit our planet, looking not out but down. Surveillance spacecraft had done that before, of course, but they paid attention only to military or tactical sites. Landsat was a notable exception, built not for spycraft but for public monitoring of how the human species was altering the surface of the planet. Two generations, eight satellites and millions of pictures later, the space agency, along with the U.S. Geological Survey (USGS), has accumulated a stunning catalog of images that, when riffled through and stitched together, create a high-definition slide show of our rapidly changing Earth. TIME is proud to host the public unveiling of these images from orbit, which for the first time date all the way back to 1984.

Over here is Dubai, growing from sparse desert metropolis to modern, sprawling megalopolis. Over there are the central-pivot irrigation systems turning the sands of Saudi Arabia into an agricultural breadbasket — a surreal green-on-brown polka-dot pattern in the desert. Elsewhere is the bad news: the high-speed retreat of Mendenhall Glacier in Alaska; the West Virginia Mountains decapitated by the mining industry; the denuded forests of the Amazon, cut to stubble by loggers.

It took the folks at Google to upgrade these choppy visual sequences from crude flip-book quality to true video footage. With the help of massive amounts of computer muscle, they have scrubbed away cloud cover, filled in missing pixels, digitally stitched puzzle-piece pictures together, until the growing, thriving, sometimes dying planet is revealed in all its dynamic churn. The images are striking not just because of their vast sweep of geography and time but also because of their staggering detail. Consider: a standard TV image uses about one-third of a million pixels per frame, while a high-definition image uses 2 million. The Landsat images, by contrast, weigh in at 1.8 trillion pixels per frame, the equivalent of 900,000 high-def TVs assembled into a single mosaic.

These Timelapse pictures tell the pretty and not-so-pretty story of a finite planet and how its residents are treating it — razing even as we build, destroying even as we preserve. It takes a certain amount of courage to look at the videos, but once you start, it’s impossible to look away.

Smart Cities Annual Conference, Budapest 5-6 June 2013


The Smart Cities Annual Conference will take place on 5th and 6th June in the beautiful city of Budapest.

After the 2012 launch event in Brussels, this year’s Smart Cities Annual Conference wants to affirm itself as a unique occasion for cities and solutions providers to meet and discuss the future shape of the European urban landscape.

In the scope of the 2013 Annual Conference, we will aim at defining the developing path of the Key Innovations; the outcome of the Working Groups’ activity.

The programme of the Smart Cities Annual Conference is rich and diversified: it alternates keynote speeches with workshops and networking sessions. Have a look at the agenda.

The Smart Cities Annual Conference proposes a mixed and diverse programme that combines audience interactivity and high-level speeches:

The first day is fully devoted to discussing Key Innovations among the relevant stakeholders: technology providers on one side and cities as users on the other, with particular attention to matchmaking possibilities. The second day focuses instead on discussing achievements and developments of the Platform itself.

Follow @EUsmartcities on twitter and keep yourself updated about the Smart Cities Annual Conference with the hashtag #EUsmartcitiesAC13

High-Def Cameras To Start Streaming Live Footage Of Earth Thanks To UrtheCast

One company is planning to launch the world’s first high definition streaming video platform aboard the International Space Station (ISS) to get a great glimpse of planet Earth from space.

UrtheCast (pronounced Earth Cast) will be launching two high definition cameras to be installed on the Russian module of the orbiting laboratory. These cameras will be streaming video of Earth back to ground stations, which will be available for users to see on the Internet, television channels, mobile devices, and other electronic media.

“From a User perspective, UrtheCast will blend features of Google Earth with the playback and video search functionality of YouTube,” the company wrote in a press statement. “The UrtheCast experience will be truly unique, generating significant awareness, publicity, and User interest worldwide.”

Users will be able to track the location of the ISS, and search for videos of a particular location. They will be able to zoom into areas, as well as rewind and fast forward areas on Earth. The cameras will be of such high-definition that they will be able to see man-made objects and groups of people, which UrtheCast says this will be comparable to Google Earth.

UrtheCast says video feeds available on the site will be free for non-commercial and private purposes. However, anyone hoping to use video for commercial purposes will be able to purchase a license to do so.

Footage will also be able to be used to access recent events, such as earthquakes or floods. A spokesman for UrtheCast said in an email that UrtheCast has an agreement with the UN to offer realtime information on disaster situations.

UrtheCast said if a competitor attempted to build and deploy a dedicated satellite to compete against the real-time feed, costs would exceed nearly $100 million for the satellite, launch, operations and ground segment.

“From a technology standpoint, it is also difficult to achieve imagery with similar data quality,” the company said. “The combination of exclusive partnerships and technology allow for substantial barriers to other would−be entrants.”

UrtheCast said it landed a deal with Discovery Science Channel to provide the high-definition footage for the television station. It said the Discovery Science Channel is working on a special segment focusing on UrtheCast technology.

“We are the home for space programming on television,” Science Channel executive vice president Debbie Adler Myers said. “Our viewers expect us to have the best, most authoritative television programs about space. UrtheCast helps us build on that promise, giving Science Channel the most stunning live images of Earth for use online and on-air.”

The Canadian company said it plans to start streaming footage of the astronauts’ view of earth by the fall of 2013. The equipment will be finished up this summer, and then shipped off to space via two Soyuz rockets. The Russian space agency will be installing the cameras beneath the ISS.

Company CEO Scott Larson said as the cameras take the images, the data basically gets stored on a hard drive on the ISS, and then at various points in the day the information is sent down to Earth. He said the delay between when you get imaged, and when the data gets sent down could be anywhere between half an hour up to a few hours.

Larson hopes the information being constantly recorded on earth will be utilized by universities, researchers, businesses and government departments.

“Coffee traders look at the coffee fields and say, ‘Is this going to be a good year for coffee or bad, do we need to import, do we need to export, is the price going to go up or down?’ Hedge funds will count the cars in Walmart parking lots to determine same-store sales,” he said.

UrtheCast is just the dawning of a new era in how we will be able to keep tabs with how life is going on Earth.
