Space Daily: A step closer to mapping the Earth in 3D.
After a year in service, the German Earth observation satellite TanDEM-X, together with its twin satellite, TerraSAR-X, have completely mapped the entire land surface of Earth for the first time. The data is being used to create the world's first single-source, high-precision, 3D digital elevation model of Earth. The German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) controls both radar satellites, generates the elevation model and is responsible for the scientific use of TanDEM-X data.

With the combining increasingly of the Geographic Information System (GIS), Remote Sensing (RS) technologies with the modern network communication technology, some unique advantages have been displaying in the monitoring, forewarning and disaster...
RS and GIS technologies were used in processing of professional meteorological data like MODIS remote sensing images, the doppler radar echoes and the Meteoroloical Information Collecting, Analyzing and Processing System (MICAPS). The system is based on WebGIS and is convenient for the use of the agro-meteorological professionals, who use biological data and monitor weather diseaster events like spring frost, heal and drought. For some model crops some object-oriented user interfaces were developed with functions of the database management, data querying, map displaying, graphics rendering, spatial analysis, the professional data processing, information extraction, figure and table output.

The evaluation criteria are based on the ability to interpolate the 100-yr return level both in terms of precision and spatial distribution. It turns out that the best results are obtained by the regionalization scheme combining the peaks-over-threshold method with kriging.
The FIFA competition has been played every 4 years since 1930, except 1942 and 1946. Morrison et al. have analised how the number of teams competing has changed dramatically over the years (13-204), as has the number of teams accepted into the finals (13-32). They prepared some extraordinary graphics showing interesting results.
There have been several attempts to provide visualizations of the relative success of the different national teams at the FIFA World Cup competitions (Fédération Internationale de Football Association (FIFA) World Cup™). This is quite a complex task, because there have been 19 competitions so far, and at least 74 teams have competed in the finals at least once. The relationships between these teams represent a network within each competition, based on their relative success at the games they play, and this network changes through time across the various competitions. Here, I review some of the previous network analyses, and then I present a combined analysis of all of the competitions based on a phylogenetic network
Given the 80 years over which the competitions have been held, there have been some changes in the political entities that the teams represent. Confusion over this issue affects some of the graphs shown below. For example, FIFA officially attributes the various results as follows: (i) all West Germany results go to Germany (leaving 1 finals result for East Germany); (ii) all Yugoslavia and Serbia & Montenegro results are attributed to Serbia (since the break-up, both Croatia and Slovenia have reached the finals independently)...
Wind is an energy that is created by uneven heating of the earth's surface which causes pressure differentials of atmospheric gases on the earth's surface. This active force has traditionally been represented on static maps ...
The Pest Tracker map can be used to see where invasive species have been identified and what areas in the United States are at greatest risk.
The interactive map is a joint effort of the USDA's Animal and Plant Health Inspection Service and state and county agencies throughout the country. The Pest Tracker is updated frequently and provides an easy to use overview of the latest local invasive species spread information. You can also use the map to find state-specific contact information to report a pest for all 50 states. With the links at left, you can see state detail pages with information on specific pests, official state contacts, and what's at risk.
Amsterdam, 23 - 27 April 2012: Knowledge Sharing through a diverse set of sessions- Exchange Forums, Plenaries, Symposia, Seminars, and Workshops.
Geospatial World Forum is a platform of convergence for all stakeholders of global geospatial community, policy makers and end users of geospatial information. Geospatial World Forum is a confluence of a variety of activities in the form of plenary, symposia, seminars, workshops, panel discussions, exchange forums- covering the vast gamut of technology, application, policy, use cases from the region and from across the world. The Forum will also host a number of additional events in parallel by its partners like board meetings, executive meetings, user meetings, partner/reseller meetings and so on.
The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) today announced that it is dedicating the month of April to sharing information about the threat that invasive plant pests, diseases and harmful weeds pose to America’s fruits, vegetables, trees, and other plants—and how the public can help prevent their spread. APHIS works each day to promote U.S. agricultural health and safeguard the nation’s agriculture, fishing and forestry industries.
...But the bottom line is this, social media is PART of the MIX but it is not the solution. AS A SINGLE CHANNEL, social will deliver very little in terms of ROI. Here's the good news, as part of a coordinated program (where social feeds email, and seo, and online ads) social media can be the "accelerant" that takes your ho hum program into something worth cheering for. But that's the long story.
The short story is this. - Facebook ROI is some of the biggest mythology in online marketing - Twitter as a lead or demand generation tool is greatly exaggerated - Google Analytics can not tell you why visitors to your site chose to buy or not buy your product - The entire mix of social media (Facebook, Twitter, Pinterest, Blogging, LinkedIn) still only accounts for 8% of the marketing budget.
And the next piece of logic is this. If you are a social media strategist, you are expected to make that 8% jump through hoops, perform miracles, AND deliver ROI (which you must demonstrate with excel driven accuracy). It can be done. Well, part of it can be done. But without the total ONLINE MARKETING MIX working together, it's like Tweeting randomly into the cavernous world of social media. You MIGHT get a RT or a tweetback response. But you are unlikely to get anything resembling success....
For international development organizations and professionals at institutions like the World Bank, every project and initiative has geospatial data. And yet this data will still gain significance in development policy and practice, because it can show the impact of projects given the contexts of climate change, urbanization, public health, and land use. Mapped data will particularly enable new resilience in the face of climate change.
The Bank uses geospatial data and owns a huge amount of it. Too often, however, the units that have produced geospatial data have had no choice but to relegate it to desk drawers, CD-ROMs, and inaccessible servers. The Bank has lacked a geospatial data repository, and there has been no central place to store and retrieve the data.
Now the Sustainable Development Network (SDN), one of the Bank’s vice-presidential units, is launching a product capable of capturing, organizing, and assisting in the analysis of geospatial data. The tool, GeoSDN (http://geosdn.worldbank.org), offers the Bank a repository for geospatial data and a web interface that enables staff to access and analyze that data. In brief, GeoSDN offers a new capability for staff to leverage development datasets and to analyze them in the context of an online mapping tool.
FutureGov Magazine. Thailand prevents forest encroachment with GIS map. By Thanya Kunakornpaiboonsiri | 8 November 2012.
Forest encroachment is a major problem Thailand has been confronting. One of the core causes of the problem derived from unclear boundaries between the conservation forest and private owned area. To prove the right over the area takes long time and complicated process in which this inefficiency has put a lot of injustice to many cases at the court, Pol Lt Col Wongseenin explained
Zebra chip (ZC, also known as papa manchada and papa rayada) is a disease that is affecting potato production in the southwestern United States and in other countries, and which has been linked to potato psyllids (Bactericera cockerelli, which infests both potatoes and tomatoes) that harbor the bacterial plant pathogen ‘Candidatus Liberibacter solanacearum’.
Until recently, the epidemiology of ZC was unknown, motivating research to elucidate the spatial and temporal patterns of ZC infections in potato fields. Studies were performed in multiple commercial potato fields located in the Texas Panhandle, wherein locations of ZC-affected potato plants were georeferenced or counted within large plots and along belt transects consisting of contiguous 10-by-10-m quadrats. The frequency of ZC infections within belt transect quadrats was well described by negative binomial and zero-inflated negative binomial distributions, in agreement with observed clustering of infections and distance-based spatial statistical results.

King County, Washington (home of Seattle) has recently undertaken an in-depth look at the value that the county has received from their GIS investment. Professor Richard Zerbe from the University of Washington’s Center for Benefit-Cost Analysis conducted the study that spans from 1992 to 2010. The report totals the investment over this 18-year span at $201 million, and the benefits at $775 million.

The digital-earth.eu network fits into Digital Agenda for Europe and links innovative centres around Europe where geo-media use is well developed. Products, resources, experiences and ideas are shared between the centres and opened to the public wherever possible.
The digital-earth.eu project examines the use of geographic media in schools and teacher education. Geo-media is the visualisation of information from different media sources and is concerned with digital content and its processing based on place, position and location.
First digital-earth.eu conference took place from July 4-8, 2011 in Salzburg, Austria. A network of accredited national and regional experts acts as multipliers, working with teachers and educators in their own countries. Currently, digital-earth.eu has 76 partners in 22 countries. There are some national and European pilot projects, but large-scale implementation is so far lacking. As a result lobbying led to meetings between representatives of EUROGEO and ESRI-Europe and the office of Commissioner Kroes in March 2012. Members of the digital-earth.eu project were invited to present a pilot project to the Commission for consideration. A follow up is planned.
Good news for Spanish-speaking readers interested in spatial analysis based on GIS applications. Our Training Manual on Spatial Analysis of Plant Diversity and Distribution, first published in 2010, is now available in Spanish.
Researchers have posted carbon stock data for the world's tropical forests on ArcGIS Online, a web-based mapping platform developed by Esri.
The data, based on satellite measurements from NASA including LiDAR and
MoDIS data as well as on-the-ground field measurements, reveals the biomass of tropical forests at a 500-meter resolution, the highest resolution ever published on a global scale. Rainforests in the Amazon, Borneo, New Guinea, and the Congo Basin are particularly carbon-dense, reflecting the importance of conserving these areas for climate change mitigation efforts.
