Looking for Park Space: Spatial Analysis with ArcGIS Online

ArcGIS Online is remaking GIS. We already take for granted how easy it is to make maps about anything and share them with anyone. And it’s not just maps. Data is becoming a social product, too. Partly through crowdsourcing (as Joseph Kerski recently wrote about here), and partly through projects like ArcGIS Open Data that help organizations offer their data like ice cream from a truck on a hot day.

But if GIS were a polygon, it would be a triangle: its vertices are maps, data, and analysis. Many people assume all analysis still has to be done in ArcGIS for Desktop. And it’s true that when it comes to geoprocessing tools, ArcGIS for Desktop is like Home Depot—it has everything you could possibly need (although you don’t always find it right away). By comparison, ArcGIS Online is like a good neighborhood hardware store. The inventory is smaller but it’s carefully chosen and more than meets your everyday needs. Continue reading

Does EarthCube Hold the “Keys to the Kingdom” of Earth Science Data?

Updated May 31, 2014

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 Face of Our Earth: Esri’s New Partnership with GEOSS

Caption

Last Update: July 31, 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

What is CyberGIS?

cybergis

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

Smithsonian’s Story Map Examines the Shale Gas Boom

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.

Understanding Our World with Landsat Data and ArcGIS

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.

The New Age of Real-Time GIS

GIS is a platform for understanding our world. In the past, the data that fueled GIS was typically created to represent the state of the geoscape at a specific moment in time (“historic” or “current”; or “future” to represent a future modeled state). While this data has proven valuable for countless GIS applications and analyses, even the “current” snapshot falls out of sync with the real world quickly. In today’s fast-paced, constantly changing world, the “current” snapshot is outdated almost as soon as it is created.

A number of new technologies are combining to enable the real time collection of data, and the sharing of that data in real time with GIS. The result is a dynamic platform which enables real time visualization, analysis, and understanding of our world. This is the new age of real-time GIS. Continue reading

Causality in Time and Space: Agent-Based Modeling for GIS Users

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.

Where Did Raymond Barone and Cliff Huxtable Go?

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.
