More than half the world’s population is now urban. Geographic information and maps are helping city governments become more democratic and participatory.
Digital maps are vital tools of municipal business, be it in planning, transportation, public safety, public works, economic development and much more to improve the quality of life. Google Maps and Uber, for example, is part of modern life, getting you “from here to there” efficiently. But long before Google was born – even before its founders were born – there was Jack Dangermond, who essentially invented the digital map, a lanky white-haired 70-year-old billionaire who is the unlikeliest of tech moguls.

Dan Scollon, at TED Talks, shows the first image photographed from Earth in 1972, which changed the human understanding of the Earth. 40 years after that image, we collected lots of information about the Earth and were developed many mapping technologies. Dan explains how maps have changed the way of understanding the world. Images of the United States and China at night can, for example, tell the energy consumption, estimate the population and reveal the distribution of this population. Such evolution made possible to evolve from primary cartography to route instructions on a 3D map to a place geocodificated on a tweet! Social networks are not just for posting happy family photos. They serve, for example, to promote revolutions as the Arab Spring. Mobile data also serve as demographic data for traffic information for example, and this Information can be converted into graphs, maps and even animations to reveal travel patterns.

Curious, in spite of not being long or new, this video introduces many topics of GIS. The video, made by ISTEC Science and Technology Information Center of Colorado State University, begins with children hunting a hidden treasure. using a modern, ergonomic GPS device. That might represent the advancement of such technology about to be operated by children in a game. Games aside, the video relates the functioning and development of satellites, GPS and GIS devices. GIS are already used by cartographers, public administrators, architects and geographers, for example, to improve the quality of life of people and animals. A professor at CSU tell us how exciting it is to work with and to be related to various economic sectors and different job opportunities: natural disaster prevention, people rescue, animal species extinguishment protection, climate change… How exciting it is to be able to zoom in and out images of the earth in different layers with different informations, and to be able to ask and solve questions related to location.
