The race to contain West Africa's Ebola outbreak (Wired UK)

The race to contain West Africa's Ebola outbreak (Wired UK) | Complex Insight  - Understanding our world | Scoop.it
Digital volunteers are racing to map regions in West Africa where the Ebola virus, which has a 90 percent fatality rate, continues to spread
ComplexInsight's insight:

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.

Limited Urban Growth: London's Street Network Dynamics since the 18th Century

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.

Urban world: Cities and the rise of the consuming class

Urban world: Cities and the rise of the consuming class | Complex Insight  - Understanding our world | Scoop.it

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.

Transforming ArcGIS into a Platform | Esri Insider

Transforming ArcGIS into a Platform | Esri Insider | Complex Insight  - Understanding our world | Scoop.it

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.

Jed Fisher's curator insight, February 6, 2013 7:10 AM

Interesting thoughts from ESRI founder Jack Dangermond.

Firstly this article gives an insight into the process of evolving a "Tool" to a cloud based "Platform" (a difficult feat in itself and something that many are pursuing in their own disciplines and fields).

Secondly, because again we are seeing the (potential) power of opening up a platform to "the masses" (aka downstream). That is, creating an open ecosystem and making complex useful data available in simpler forms for downstream users. In turn, some would argue that if you can get people hooked on your data then it will increase the need for more contact (demand and supply equation).

People talk about "Big Data" all the time however it's often overlooked that the data must come from somewhere. I love that we are seeing more and more disciplines open up. CAD, AEC, GIS, and Manufacturing all seem to be trending towards opening up their platforms and their resulting data which in turn allows us to (potentially) have an incredible, powerful and connected experience.

UK Ordnance Survey goes international - Spatial Source : Australasia's magazine for the surveying, mapping and geoinformation industries | Complex Insight  - Understanding our world | Scoop.it

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.

Spatial Patterns and Spread of Potato Zebra Chip Disease in the Texas Panhandle

Spatial Patterns and Spread of Potato Zebra Chip Disease in the Texas Panhandle | Complex Insight  - Understanding our world | Scoop.it

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.
