Geographic Information Systems: 30 educational videos

The intrinsic geolocation in almost everything we do, using electronic devices, has made the GIS issue more urgent to apply every day. 30 years ago, talking about a coordinate, a route or a map was a circumstantial matter. Used only by cartography specialists or tourists who could not do without a map during a trip.

Today, people consult maps from their mobile devices, tag places from social networks, collaborate by mapping without knowing it, and insert a spatial context in an article. And all of this is good for the GIS sector. Although the challenge is still complex, since it continues to be a discipline in which many sciences intervene, all of them with complexities from heaven to hell.

The time will come when using geographic information will become routine. And I'm not talking about showing a map, but about calling layers, theming, creating a buffer, modeling a 3D environment. For that, it will be necessary to separate the specialty of usability, as well as using a mobile phone today; nobody occupies being a specialist in all the disciplines involved in its elaboration. Meanwhile, it is necessary to learn from GIS. More than using a tool, understand the fundamentals of the flow of cartographic data, from its production to its availability to the user who will provide feedback.

It is a pleasure for me to present the series of educational videos about the Geographic Information Systems series. Ideal for those who want to understand the fundamentals, principles, applications and trends of GIS, developed in 30 videos compressed to graphic segments no longer than 5 minutes.
