Digital volunteers are racing to map regions in West Africa where the Ebola virus, which has a 90 percent fatality rate, continues to spread
The use of OpenStreetMap (OSM) as an unifying geodata system is increasing in humanitarian aid. The current Ebola outbreak in West Africa is a challenge at multiple levels for teams trying to coordinate a response. Due to years of war there are few up to date maps in the region and multiple boundaries mean different groups are collecting data. Digital volunteers creating new OSM entries will be a key asset in enabling health officials to manage the outbreak and hopefully bring things under control.
We investigate the growth dynamics of Greater London defined by the administrative boundary of the Greater London Authority, based on the evolution of its street network during the last two centuries. This is done by employing a unique dataset, consisting of the planar graph representation of nine time slices of Greater London's road network spanning 224 years, from 1786 to 2010. Within this time-frame, we address the concept of the metropolitan area or city in physical terms, in that urban evolution reveals observable transitions in the distribution of relevant geometrical properties. Given that London has a hard boundary enforced by its long standing green belt, we show that its street network dynamics can be described as a fractal space-filling phenomena up to a capacitated limit, whence its growth can be predicted with a striking level of accuracy. This observation is confirmed by the analytical calculation of key topological properties of the planar graph, such as the topological growth of the network and its average connectivity. This study thus represents an example of a strong violation of Gibrat's law. In particular, we are able to show analytically how London evolves from a more loop-like structure, typical of planned cities, toward a more tree-like structure, typical of self-organized cities. These observations are relevant to the discourse on sustainable urban planning with respect to the control of urban sprawl in many large cities which have developed under the conditions of spatial constraints imposed by green belts and hard urban boundaries.
ESRI's acquisition of CityEngine is probably one of the smartest tech acquisitions in the geospatial market in a long time. As the product and technology integration rolls forward we get to see how very smart the acquisition was.The WebGL publishing capabilities are very exciting for city planners. Great video of highlights from the recent ESRI user group conference its great seeing how the products are evolving.

Stanford scientists have identified key acoustic characteristics of the 2011 Japan earthquake that indicated it would cause a large tsunami. The technique could be applied worldwide to create an early warning system for massive tsunamis.
Computer simulations by Stanford scientists reveal that sound waves in the ocean produced by the earthquake probably reached land tens of minutes before the tsunami. If correctly interpreted, they could have offered a warning that a large tsunami was on the way. Click on the image or title to learn more.

Cities have long been the world’s economic dynamos, but today the speed and scale of their expansion are unprecedented. Through a combination of consumption and investment in physical capital, growing cities could inject up to $30 trillion a year into the world economy by 2025. Understanding cities and their shifting demographics is critical to reaching urban consumers and to preparing for the challenges that will arise from increasing demand for natural resources (such as water and energy) and for capital to invest in new housing, office buildings, and port capacity.

A predictive data analytics team in the Mayor's Office of New York City has been quietly using data science to find patterns in regulatory data that can then be applied to law enforcement, public safety, public health and better allocation of resources. In a good interview Michael Flowers explains why applying data science to regulatory data is necessary to use city resources better. This is the other aspect of smart cities - better analytics and models informing policy and practise. Worth readig. Click on the image or headline to learn more

2013 Esri International User Conference in San Diego, California, from July 8-12, 2013. Esri's yearly user conference is the largest geospatial conference.
ESRI maybe the grandfather company of the GIS industry- but they constantly innovate and their user base does incredible things with their GIS technologies. The annual ESRI user conference is a great source of info and the videos from the key notes are worth watching. If you can take time to watch the STEM & GIS in schools with the incredibly impressive student team from Roosevelt High School and then watch the Will.iam and Jack Dangermond interview. .
Palantir's data platform, Gotham, enables data integration, search and discovery, knowledge management, secure collaboration, and algorithmic analysis across a wide variety of data sources.
Palantir teamed with the OpenGeo to extend PostGIS to support WGS84 coordinate system and geodetic coordinates. This enabled Palantir to migrate from Oracle spatial to PostGIS as the underpinning spatial database for their Gotham platform. The benefits to the wider spatial community are signficiant since WGS84 based mapping is often a requirement in government and geoscience applications. Palantir's sponsored open source development undertaken by OpenGeo enables other to take advantage of the new features and integrate PostGIS into workflows. Click on the image or title to learn more.

Transforming ArcGIS into a Platform, One of the primary drivers of the ArcGIS as a platform initiative has been making GIS easier not only for new users but for advanced users, as well. In addition, the platform is open, extendable, and can be leveraged by others, facilitating both the integration of other geospatial technologies, as well as other enterprise IT and web services of many origins. Looking to the future, we see our platform strategy as being of great benefit and value to our users, partners, developers, and ultimately the world itself. It is already creating an ecosystem and community of GIS users who are leveraging each other’s resources and knowledge.

Having grown up relying on Ordance Survey maps for climbing and hill walking and hiking - I have a fond spot for the Ordanace Survey and their products. So this caught my eye from September 2012, the UK geospatial information agency, Ordnance Survey, will be launching a new international organisation, Ordnance Survey International. The aim is to provide advice and services across the full spectrum of Ordnance Survey’s expertise, including data collection and maintenance, product development and geospatial data management. Dr Vanessa Lawrence CB, director general and chief executive at Ordnance Survey added that “for some time the organisation has been approached by other national mapping agencies to provide guidance and share their expertise. Following encouragement by Ministers to export the skills, Ordnance Survey International has been set up to facilitate working with overseas customers who wish to seek our assistance.

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.
