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
GIS users had lots to cheer about in 2012, with major releases of software with important new capabilities. These deliveries have also set the course ahead for what’s to come in 2013. Here’s a quick look back on the past year, with a glimpse at the year ahead.
Clearly a significant release, and one of the best and most comprehensive updates in many years, the big milestone for Esri professional GIS users this year was ArcGIS 10.1, fulfilling many initiatives introduced in 2010 with ArcGIS 10.0. Beyond the new features and functions it delivered, ArcGIS was transformed, becoming a complete and unified system, with integrated online and mobile capabilities to support a variety of workflows and needs.

Like it or not, we are all aging. In 2000, the median age in the United States was 35.3 years. By 2010, this number had increased to 37.0 years; today, the median age is 37.3 years. By 2030, seniors will comprise 20 percent of the total US population. In addition to people living longer, the jump in the US median age is also due to aging Baby Boomers.
Seniors are not one monolithic demographic cohort. From those aged 55 to those in their 80s and older, seniors have vastly different lifestyles, preferences, and spending habits. These differences become even more apparent when classified by demographics such as affluence, education, employment, and race/ethnicity. Data about product and media preferences, leisure activities, and shopping habits provides even more detail. Continue reading
A great map often starts with a great basemap. It’s the canvas upon which we paint our operational layers, providing context and bringing them to life. Esri has published many different kinds of basemaps, including Streets, Imagery, Topographic, and more. These basemaps are continually updated as new information becomes available.
One of the most popular basemaps (and the default ArcGIS Online basemap) is the World Topographic basemap, also known as the “Community Basemap.” It’s a GIS crowd-sourced basemap that compiles data from many GIS users that participate in Esri’s Community Maps Program.
The basemap is compiled from the best available sources, and includes boundaries, cities, water features, physiographic features, parks, landmarks, transportation, and buildings. Updates are published monthly, and you can find more details on ArcGIS Online.
