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
Jack Dangermond studied under Ian McHarg and Carl Steinitz, the combination of which took the manual overlay method of designing with nature from paper to the digital world using computers in 1969. His hope was that GIS would become a framework for modeling earth’s systems so they could be managed more sustainably. In 1995, Jack called GIS “the nervous system of the planet,” foreshadowing what I think GIS is on its way to becoming. Geodesign–an iterative design method that uses stakeholder input, geospatial modeling, impact simulations, and real-time feedback to facilitate holistic designs and smart decisions–is the natural evolution of that vision.
By the time you see the image below it will be way out of date.
From Worldometers, it’s snapshot in time of the current world population which, depending on your source, is growing at a rate of somewhere between 75 and 140 million people each year. Proving, if nothing else, that humans are quite prolific.
“Four score and seven years ago” began what time would remember as a milestone in American history. On November 19, 1863, President Abraham Lincoln delivered the Gettysburg Address, a speech that many consider among the most eloquent and important of … Continue reading
Climate change and its effects are fundamentally geographic challenges that require a geographic approach, where we endeavor to understand the constraints a changing climate imposes upon the terrestrial and aquatic systems we depend.
Geography is a powerful multidimensional framework enabling scientists to explore data layers, discover emergent new patterns, and test alternative scenarios; so we can understand the risks, develop proactive adaptation strategies, and increase society’s long-term resilience to climate change through policy modification. Esri is committed to providing tools to accelerate the global community’s ability to access content, do analyses and share results. Continue reading
Our friends at GISi recently published a great post about how one of their non-GIS people created a story map. One of our writers had just created a Halloween-themed story map and we thought it would be interesting to learn more about his experience.

As a writer, I never thought I would create a story map. I have some technical knowledge, but the artistry and rich functionality behind some of our story maps just seemed way out of my reach. After creating The Geography of Horror story map, I’m now proud to say that I couldn’t have been more wrong. Not only is it easy to create a story map, but it’s also relatively easy to put your own unique touch on one.
A city looks and feels the way it does because of human intention. Early civilizations built their settlements next to waterways, designing them to accommodate this resource accessibility and their own survival. During the beginning of the industrial revolution, cities were planned with ever-evolving rules ensuring that city streets were wide enough to accommodate the full turn of a horse and carriage. In this way, the values of the people were encoded into the very DNA of the city.
A complex built environment can be reduced to three basic elements: links along which travel can occur, nodes representing the intersections where two or more paths cross and public spaces form, and buildings where most human activities take place. The functionalities of place are all defined by rules and procedures, which make up the core design vocabulary of a place. Procedural design techniques automatically generate urban designs through predefined rules which you can change as much as needed, providing room for limitless new design possibilities.

GIS Responds to the Tough Questions
Electric utilities face a new world–one in which the infrastructure is aging along with the workers. The price of everything keeps going up. Customers want better and faster service, but some of them cannot pay their bills. Natural disasters seem to get nastier each year. Governments continue to dole out more and more regulations. The community wants better service, lower emissions, and fewer mishaps. It’s a political nightmare to raise rates. Plus, the new smart grid devices are smothering utility operators with data.
In short: utilities cannot continue to operate as they have been. Utilities need a better way to do business. GIS can help. Continue reading
Stories are spoken in many languages, and the same is true for Story Maps. The results of a story map competition held at the recent Esri France SIG 2013 conference offered some compelling examples for me.
The winning story map merged themes of culture with urban and industrial heritage, but my favorite was a photographic tour of the Paris Metro. This was a tough selection to make over my second favorite story map about the seasonal migration (or transhumance) of people and their sheep. Of course all of these story maps are in French.

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
