Anyone living in a major U.S. city for the past decade may have noticed a change in the air. The change is apparent in new NASA satellite images unveiled this week that demonstrate the reduction of air pollution across the country.
After ten years in orbit, the Ozone Monitoring Instrument (OMI) onNASA’s Aura satellitehas been in orbit sufficiently long to show that people in major U.S. cities are breathing less nitrogen dioxide – a yellow-brown gas that can cause respiratory problems.
Nitrogen dioxide pollution, averaged yearly from 2005-2011, has decreased across the United States.

Nitrogen dioxide is one of the six common pollutants regulated by the U.S. Environmental Protection Agency (EPA) to protect human health. Alone it can impact the respiratory system, but it also contributes to the formation of other pollutants including ground-level ozone and particulates, which also carry adverse health effects. The gas is produced primarily during the combustion of gasoline in vehicle engines and coal in power plants. It’s also a good proxy for the presence of air pollution in general.
Air pollution has decreased even though population and the number of cars on the roads have increased. The shift is the result of regulations, technology improvements and economic changes, scientists say.

Today Redfin (www.redfin.com), the customer-first real estate brokerage, released an infographic that connects each of the 31 non-U.S. countries participating in the 2014 World Cup with a U.S. city that has many residents who were born there. The graphic illustrates where there are likely to be pockets of people from other countries rooting for their home team.
For example, there are a number of people who were born in Belgium but currently live in Santa Barbara, so it’s likely there will be some lively banter going on there during today’s match between the U.S. and Belgium.
To generate the graphic, Redfin started with U.S. Census data for foreign-born residents across all metro areas in 2012, then narrowed it down to metro areas with at least 200,000 total residents and at least 100 residents born in the World Cup country. For the illustration, each city could only rank for one country. Otherwise, cities such as New York, Washington D.C. and Miami, which have large populations of foreign-born citizens, would dominate the map. For example, once Miami ranked for Colombia, it was not able to rank for any other countries, even though the city also has a lot of residents who were born in Argentina and Uruguay.
With 13 percent of the U.S. population born in another country, it’s easy to find excited fans cheering on almost every team participating in this global competition that happens only once every four years.

Redlands, California—July 1, 2014—Two of the nation’s most authoritative mapping sources, theU.S. Geological SurveyandEsri, have partnered to put the rich tapestry ofU.S. Historical Mapsinto the hands of everyone. Available in time for the Fourth of July and able to be accessed on all digital devices, the USGS Historical Topographic Map Explorer brings to life more than 178,000 maps dating from 1884 to 2006.
In the past, the USGS historical maps were available only as printed lithographic copies. More recently, the legacy quadrangles were made available as free, downloadable GeoPDF®versions as part of the USGSHistorical Topographic Map Collection. The USGS Historical Topographic Map Explorer application allows users to access the historical maps as high resolution georeferenced images for use in web mapping applications, and features a timeline to easily select the desired maps.
“We are so pleased to see these historic topographic maps being made more accessible to the nation,” said Kevin Gallagher, associate director of Core Science Systems for the USGS. “We recognize the fundamental role of government in acquiring mapping information and putting it in the public domain. At the same time, we recognize the tremendous benefits of the private industry adding value through innovative approaches to access and distribution.”

Later this month, the app will be available inGitHub, allowing the GIS community to create their own scanned and geo-referenced collection, configure the app, and see these digital collections come to life.
“We are pleased to partner with the USGS on this app to bring this national treasure to life,” said Jack Dangermond, president, Esri. “This application provides an easy way for anyone to explore the historic map collection by both place and time. The ArcGIS platform supports the building and sharing of amazing maps and content, such as this wonderful collection.”
The USGS Historical Topographic Map Collection was officially launched on September 12, 2011. The project has been largely successful, with more than 6.8 million downloads to date. The project goal was reached in September, 2012 for the lower 48 states, Alaska in mid-October, 2012, and periodically adds new historical maps when discovered and scanned.
June 19, 2014—MapLight, a nonpartisan research organization that tracks the influence of money in politics, announces the launch of an extensive mapping project examining the geographic origin of contributions to legislators by state; contributions from companies to legislators by state; and roll call votes by state and district on key bills in Congress. For the first time, it will be possible to instantly see and understand the role money from outside sources plays in local races and the geographic alignment of support and opposition to key legislative initiatives.
With Rep. Eric Cantor (R-Va.) on his way out of Congress, the House Republican Caucus is working to replace him as Majority Leader, the second highest-ranking leadership position in the House of Representatives. According to House.gov, the Majority Leader "is charged with scheduling legislation for floor consideration; planning the daily, weekly, and annual legislative agendas; consulting with Members to gauge party sentiment; and, generally working to advance the goals of the majority party." The Majority Leader also plays a key role in raising funds to help their party retain majority control of the House.
House Republicans will meet today, Thursday, June 19, 2014, to vote on electing a new Majority Leader. Below is a geographical look at contributions by state to leading contender, Rep. Kevin McCarthy (R-CA), from interest groups and individuals.

CORPUS CHRISTI, Texas – As the Gulf Coast begins another hurricane season, researchers with the Conrad Blucher Institute for Surveying and Science (CBI) at Texas A&M University-Corpus Christi will be improving the data collection system to allow for more accurate planning and predictions for flooding and sea level rise.
CBI has been awarded $1.35 million to enhance the National Spatial Reference System that helps model and predict sea level rise.
Forecasters are predicting a hurricane season with one or two major hurricanes, but flooding can still pose significant threat, especially to the vital infrastructure along the Gulf coast, which includes 10 of the 14 largest ports. The long-term stability of this region’s infrastructure is in question due to the impact of sea level rise and associated increases in risks of flooding. Growing Gulf coastal populations, up 32 percent from 1990 to 2008, compound the risks. Preparing for sea level rise, flooding and other impacts requires accurate data about what’s occurring at the water’s edge. Collection methods for this type of geospatial data will be enhanced through this project.
The funding, from the National Geodetic Survey, a project of the National Oceanic and Atmospheric Administration, provides the foundation for modeling along the northern Gulf of Mexico through the National Spatial Reference System.
The project focuses on an area that is most exposed to inundation from tropical storm surge and has a high risk of flooding and long-term effects of climate change and subsidence.
“We are excited to be part of this project to provide the latest geospatial data with information from tide gauges, sea level observations, land elevation reference points, and 3D positioning,” said Dr. Gary Jeffress, Director of CBI. “This system will help local and regional leaders plan for improved resilience to the impacts of sea level rise and flooding and develop long-term strategies to address impacts along the northern Gulf of Mexico.”
The project will extend and improve monitoring stations from Texas to the Florida Keys to provide additional measurements, including more accurate data regarding elevations, 3D positioning, subsidence rates and sea level observations, that will establish ongoing monitoring of the relative sea-level change along the northern Gulf of Mexico in the coming decades.
Dr. Jeffress, Dr. Ruizhi Chen and James Rizzo, with CBI and Texas Spatial Reference Center, will lead the project for A&M-Corpus Christi. Researchers from University of Southern Mississippi, Louisiana State University and Florida Atlantic University are also partners in the project.
