Geography and ecology are key factors that have influenced the genetic makeup of human groups in southern Africa, according to new research discussed in the journal GENETICS, a publication of the Genetics Society of America. By investigating the ancestries of twenty-two KhoeSan groups, including new samples from the Nama and the ≠Khomani, researchers conclude that the genetic clustering of southern African populations is closely tied to the ecogeography of the Kalahari Desert region.

A global cropland percentage map and a global field size map have been created for the first time to guide scientists and policymakers interested in global agricultural modelling and assessment. Both maps are for the baseline year 2005 and combined multiple data sets from global, regional and national levels to achieve a high level of accuracy and 1 km2 resolution.

Nearly 85% of residents in central Dublin, Ireland, could be exposed to damaging levels of night-time traffic noise, according to a recent study. The researchers explain how they assessed population exposure to noise and calculate the impacts of several noise reduction measures, providing information that could help EU Member States meet the Environmental Noise Directive’s requirements.

Major roads, railways, airports and industrial areas can be a major source of noise nuisance for local communities. To help city planners and architects determine the most appropriate sound insulation design for the exterior of buildings, Turkish researchers have developed a new method that transforms noise maps into insulation maps.

Researchers in Greece have added a new dimension to noise level mapping by including data on residents’ perception and value of different sounds. This consideration of the experiences of residents in this way could lead to more effective policy implementation.

Digital noise maps developed under the EU’s Environmental Noise Directive (END) are a useful way of assessing traffic noise exposure for local residents, according to a recent Swedish study. The END maps could also be used to standardise noise exposure information in noise and health research.

A study of two forest ecosystems in Spain has found that land-cover maps of watersheds, ecosystems hosting key interactions between vegetation, wildlife, and water, are made more accurate by the inclusion of LiDAR data — a type of remote sensing that pulses laser light at a target to measure vertical distances for use in 3D-mapping an environment. This has important implications for ecosystem monitoring, flood mitigation, and forest management, fields in which accurately characterising an environment is key.

A new tool has been developed to map the sensitivity of seabirds to offshore wind farm development. The Seabird Mapping and Sensitivity Tool (SeaMaST), currently for use in English waters, combines information on the sensitivity of seabird species to wind turbines with data on the birds’ distribution. It provides maps that can be used for both the offshore wind farm industry and marine spatial planning.

Ecological risk maps showing 'hotspots' of risk to wildlife from single or combined soil pollutants have been developed. These maps can be used to improve risk analysis and stakeholder communications.

One the most exciting new books in a long time has been released this month: Glen Creason's Los Angeles In Maps (New York: Rizzoli, 2010).

Creason is the Map Libraran at Los Angeles Public Library and co-curated the landmark 2008-2009 exhibition L.A. Unfolded: Maps From The Los Angeles Public Library.

This new work guides the reader through the variety of maps created for Los Angeles, from the 1849 Plan De La Ciudad De Los Angeles ("Ord's Survey") to modern day interactive maps.

The book works on a number of levels: as history lesson, as a beautiful coffee table book with intriguing graphics, as a thought-provoking work showing how spatial depictions have changed over the past century and a half, and how Los Angeles can be viewed in historical context in ways other than chronological.

It is organized into chapters that tell the various stories of Los Angeles, such as Early Growth, Social Life, Water, Age of the Automobile, Tourism, etc.

Fortunately for us, there is a Transportation section, where we learn the story of Laura J. Whitlock, official mapmaker of Los Angeles County - and the only female map publisher in the United States when she was working in the early 20th century.

Pirated copies of her work were widely distributed without her consent, and she filed suit for copyright infringement. We'll leave it to you to discover what happened with this landmark case, but it did set a precedent for map copyright -- an important contribution to American map history made here in Los Angeles.

The rest of the transportation maps and information are equally interesting, as are the other subject areas covered, but you'll have to read the book yourself to find out more.

Google Maps has added a sharing feature. You can track your favorite places and share them with your friends.

Antonio Petrucelli’s name is probably unfamiliar to map people, although it shouldn’t be. Petrucelli was one of the artists whose work was commonly found on the cover (and inside) Fortune magazine from the 1930s through the 1950s. Petrucelli collaborated with Richard Edes Harrison and was a contemporary of Boris Artzybasheff. Like Edes Harrison and Artzybasheff, […]

Given an one-dimensional Lorenz-like expanding map we prove that the conditionlinebreak $P_{top}(phi,partial mathcal{P},ell)<P_{top}(phi,ell)$ (see, subsection 2.4 for definition), introduced by Buzzi and Sarig in [1] is satisfied for all continuous potentials $phi:[0,1]longrightarrow mathbb{R}$. We apply this to prove that quasi-H"older-continuous potentials (see, subsection 2.2 for definition) have at most one equilibrium measure and we construct a family of continuous but not H"older and neither weak H"older continuous potentials for which we observe phase transitions. Indeed, this class includes all H"older and weak-H"older continuous potentials and form an open and [2].

We construct a smooth moduli stack of tuples consisting of genus two nodal curves, line bundles, and twisted fields. It leads to a desingularization of the moduli of genus two stable maps to projective spaces. The construction of this new moduli is based on systematical application of the theory of stacks with twisted fields (STF), which has its prototype appeared in arXiv:1906.10527 and arXiv:1201.2427 and is fully developed in this article. The results of this article are the second step of a series of works toward the resolutions of the moduli of stable maps of higher genera.

Described herein are methods and systems for generating shared collaborative maps for planting or harvesting operations. A method of generating a collaborative shared map between machines includes generating a first map for a first machine based on a first set of data and generating a second map for a second machine based on a second set of data. The method further includes generating at least one shared collaborative map for at least one of the first and second machines based on the first and second maps.

A geography game for learning geography and geographic information is disclosed that includes maps, scoresheets, lists of facts, and rules and instructions used to guide players on how to effectively use edible food items, such as chips, to learn geography through a fun and entertaining platform. The game provides marketing value to chip manufacturers and variations of the game add even more value by creating excitement and longevity. In one implementation, the edible chip is a triangular corn tortilla chip.

It doesn’t matter what website you’re looking at, every site online has something that naturally catches your attention. It could be a picture, a graphic, a video, there will be something that naturally stands out and gets your attention. If you’re looking at turning your website into a source of revenue you want your ads or products displayed in such a way that they grab your visitor’s attention. There are two ways you can go about doing this, the wrong way which is to force your ads on people which will drive them away from your site. Or using heat maps to attract your visitors to them without forcing them..........
