With all the recent excitement and good hopes over the White House Climate Data Initiative, and the ongoing progress of the Group on 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).

The Esri R&D Center in Portland, Oregon works on two main projects: developers.arcgis.com and the Esri Geotrigger Service. In our free time we also build and maintain open source tools to help us get our work done more easily. Here’s … Continue reading
Last Update: March 29, 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. The … Continue reading
Hydraulic fracturing, or fracking, is transforming communities across the US above shale rock layers that trap natural gas and oil. Fracking involves the injection of millions of gallons of water and other fluids into shale deposits under high pressure, causing fracturing of the surrounding rock and the release of gas through nearby wells. The extraction technique is controversial, and the resulting changes to nearby communities are argued as both good and bad.
Landsat data from the United States Geological Survey (USGS) is one of the best sources for understanding and analyzing changes to our world that have occurred over the last 40 years. With the launch of Landsat 8 in February of this year, the continuity of the program is assured into at least the next decade. Esri continues to support making Landsat imagery and image processing part of our platform and has recently added more capabilities to ArcGIS that make it even easier to analyze and enhance Landsat data.
Kevin Johnston has been part of Esri’s software development team for more than 20 years, focusing on the ArcGIS Spatial Analyst extension and various aspects of dynamic and statistical modeling. In addition to working at Esri, Kevin does volunteer conservation work on a variety of conservation projects, including elephant-movement models for Amboseli National Park in Kenya, snow leopard corridor models in Nepal, and agent-based models of cougar movement in Arizona. With the release of a new book he edited called Agent Analyst: Agent-Based Modeling in ArcGIS, I asked Kevin to share some basic information on agent-based modeling and how the GIS community might leverage it in their projects.

Change has been the constant for the US demographic landscape recently. Two major demographic differences since Census 2000 are the growth of minority populations and changes to household composition. Traditional households of “dad, mom, two kids, and a dog” are no longer the norm. Household types are changing and evolving, so it may be a slow goodbye to the household types portrayed in “Everybody Loves Raymond” and “The Cosby Show”, and hello to a group of entirely different kind of households.

We’re fortunate to be engaged as GIS professionals today. Never before has there been so much potential to transform the work we do and the organizations we serve geospatially. What do we need for this transformation? We need authoritative data at … Continue reading
