Runners (and race fans) take your mark. Today is the 2016 Boston Marathon, held every April on the Massachusetts holiday Patriots’ Day, which commemorates the start of the American Revolutionary War. It’s a spirited race, one that attracts about 30,000 runners, half a million spectators, and international media coverage.
Amid all the excitement, and new shoes, lurk safety concerns.
Take yourself back to spring 2013, the 117th running of the Boston Marathon. That day two bombs exploded at the finish line killing three people and wounding 260.
The following year marked record-high participation from runners and spectators under the rally cry: Boston Strong. By 2015, the Massachusetts Emergency Management Agency had produced the Boston Marathon Dashboard, an online map that tracks every aspect of the event as it happens.
It is Earth Science Week! Since October 1998, the American Geosciences Institute has organized this national and international event to help the public gain appreciation and understanding of Earth Sciences and to encourage stewardship of the Earth. We want to … Continue reading
Esri’s World Population Estimate, a new probability surface that estimates the location and count of people throughout the world, is now available in ArcGIS Online.
Esri has been producing a global population estimate in ArcGIS Online for several years. This data is in the form of point features with population counts and characteristics assigned to each point; and it is used behind the scenes in apps such as Business Analyst Online, Community Analyst, and Esri Maps Apps. That may sound simple, but those points are big data; with nearly a billion locations represented. The Geographic Data Enrichment tools depend on those points as the basis for describing the characteristics of local populations in countries lacking a census or countries that do not make detailed census data available.
Based on this earlier point data work, Esri released the World Population Estimate (WPE) in December 2014. WPE takes the form of a raster surface, which is far easier to make available in ArcGIS Online and use in analysis models than the previous point data. Continue reading
Last update: March 16, 2016 Spatial analysis has always been a hallmark of GIS, the “numerical recipes” which set GIS apart from other forms of computerized visualization and information management. With GIS we can pose questions and derive results using … Continue reading
Story Maps are fun, easy, and informative. Their popularity is documented by the many interesting examples you will find at the Story Maps Gallery. An enduring favorite of mine is not the most sophisticated, or provocative, or one that required … Continue reading

With all the recent excitement and good hopes over the White House Climate Data Initiative, and the ongoing progress of the Global Earth Observation System of Systems (GEOSS), there is another huge data initiative that bears mention: EarthCube.
I have used the word “initiative” for EarthCube but it has also been described as a vision, as a multi-faceted, multi-layered partnership, and also as a “virtual organization.” As such, it bears quite a bit of resemblance to the international GEOSS, but is much more US-based, having been conceived and currently funded by the US National Science Foundation (NSF).

Last Update: December 10, 2015 In early January of 2014, we heard quite a bit about the polar vortex (not a new term, by the way) as North America struggled with some of the most frigid and dangerous temperatures seen … Continue reading
In an earlier post, I had mentioned Esri’s involvement in the large National Science Foundation-funded project known as CyberGIS, which aims to establish a fundamentally new software framework via a seamless integration of cyberinfrastructure, GIS, and spatial analysis/modeling capabilities, particularly … Continue reading
“Are we there yet?”
Vacationing parents usually answer this familiar question with a resounding “No!” The inquiry also resonates with economists who agree that median household income in the United States is “not there yet.”
Median household income is nowhere near the pre-Great Recession figures. According to Esri’s Updated Demographics data, median household income was $53,150 in 2007. During calendar year 2008 (the first year after the start of the recession), median household income rose to $54,700. In the intervening years, median household income fell from $54,700 in 2009 to $54,442 in 2010, and dropped in 98 percent of US counties. In 2013, Esri’s Updated Demographics data notes that with a figure of $51,314, median household income is still in recovery, increasing by only $1,157 from $50,157 in 2012. Continue reading
Among the current top stories on Smithsonian’s website is a “then and now” perspective of a handful of cities using David Rumsey’s historical maps and current aerial imagery in an interactive application. The applications were built using one of the … Continue reading
