Next-generation techniques are already changing the way we do science. Recently the National Academy of Sciences convened a Workshop on Identifying Transformative Research in the Geographical Sciences. Given that so many of the challenges that we currently face are place-based … Continue reading
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
“So many of the world’s current issues—at a global scale and locally—boil down to geography, and need the geographers of the future to help us understand them.”
“What is the capital of Madagascar?”
Unfortunately, that’s what most people think of when they hear the term geography.
“It’s boring,” they say. “It’s the study of useless information. It has no practical relevance to my life.”
In fact, nothing could be further from the truth. Geography is one of the most interesting, vibrant, and dynamic fields of study today. It’s also one of the most vital.
Geography has at least one thing in common with other disciplines: it has become fragmented. As our world has become more complex, science has responded by becoming narrowly focused. Thousands of very smart people are making remarkable discoveries in their own disciplines. But who is looking at the big picture?
It’s only logical. When life gets complicated, we often tend to focus on the little things. It helps us deal with being overwhelmed. But at some point we need to take a step back and realize that we can’t understand an entire forest if we’re addressing issues one tree at a time.
We’ve done an admirable job examining and understanding a multitude of component pieces that make our planet work. Now our grand challenge is to integrate all this knowledge so we can understand the “big picture.”
How do we put all of the pieces back together again so that we can understand the whole? How do we defragment geography?
Geography—the scientific foundation of GIS—has for many years been concerned with exploring and describing our world. Historically, explorers lead grand expeditions to the farthest reaches of the globe. This golden age of exploration contributed greatly to our understanding of how our world works.
This was followed by the space age—an era where we left the planet and turned our cameras and sensors to look back on our home, giving us an entirely new perspective. Bound to the surface of earth for millennia, humankind was getting its first opportunity to look at our planetary system as a whole—from a few hundred miles up in space.
