Part of Jack Dangermond’s “GIS Creating Our Future” presentation at 2014 Esri User Conference. Our world is facing serious challenges like population growth, poorly planned urbanization, pollution, energy use, climate changes, natural disasters, food production shortage and many others… Continue reading JACK DANGERMOND: “GIS CREATING OUR FUTURE” AT 2014 ESRI UC
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.

A short ESRI animation explaining Geographic Information Systems in a specially didatic way. GIS is a system to record, analyze and present spatial information on maps, allowing better decision making using geography. Traders use GIS to choose the location of new stores to sell specific products to the local public. It’s used by environmental organizations to mitigate the consequences of global warming. Electric companies use to locate specific parts that need repairs and to do them more efficiently. The police use it to identify patterns in criminal activities and plan operations more strategically. View information and trends is much easier on maps than spreadsheets. GIS is a software that runs on computers connected to powerful servers, which can now be accessed even by smartphones. GIS are informations about the real world divided into layers. Each layer contains informations of the same type. Continue reading WHAT IS GIS?
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.
