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: April 26, 2015 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 pose questions and derive results using a … 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: November 23, 2014 In early January, 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 in a … 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
The outbreak of bad weather that has plagued the US over the past few weeks has created a significant need for access to location data and pre- and post-event map imagery. I was recently on a call with a former colleague who was looking for the latest post-event imagery. He described how imagery and other recently available features of ArcGIS Online, Esri’s cloud-based mapping platform, were having a significant impact on streamlining their claims workflow and efforts to effectively align field resources.

Atlases have long been used by people to help navigate and understand our world. A traditional atlas consists of a collection of static maps portraying various aspects of geography, bound together in book form and updated with new information at long intervals. The geography covered, in terms of both themes and extent, is set in stone for any given atlas, and the thematic information is typically created and authored by a select few authoritative sources.
These traditional atlases have served us well for many hundreds of years. But today, the world is changing rapidly, and it’s difficult for traditional atlases to keep up with the pace of that change. To help us keep pace with our evolving planet, our concept of what exactly constitutes an atlas must also evolve. Continue reading
