Geographic Information Systems

Geographic Information Systems

Aronoff (1989) described a GIS as any manual or computer-based set of procedures to store and manipulate geographically referenced data.

GIS ‘Geographical Information System’ is an computer-based tool for mapping and analyzing things that exist and events that happen on Earth.
A GIS consists of:
Digital Data –– the geographical information that you will view and analyse using computer hardware and software.
Computer Hardware –– computers used for storing data, displaying graphics and processing data.
Computer Software –– computer programs that run on the computer hardware and allow you to work with digital data. A software program that forms part of the GIS is called a GIS Application.

With a GIS application you can open digital maps on your computer, create new spatial information to add to a map, create printed maps customized to your needs and perform spatial analysis.

GIS has significant importance in various professional areas such as urban planners, Geologists, foresters and others, to provide organized geographic information and allow analyze this information.




Opera Mobile Store Will replace the Nokia Store

The partnership between Microsoft, Nokia and Opera now appears to be taking a step further with the passage of the Nokia applications store for the control of Opera. This new agreement aims to ensure that all entry-level phones from Microsoft are served with an application store that can meet their needs and is prepared for the future offer the best deals. The need to exchange shop lies in the fact that Microsoft want to "disappear" Nokia all their products and do not want to keep the current store of Nokia. The new store will serve all equipments range of Microsoft, and all models of the Series 40, Series 60, Symbian. The migration of users from the current store for the Opera will begin soon and should be completed at the first half of 2015. Then, the app store will be closed from Nokia.


Because knowledge is never too much...

Coursera is an education platform that allows everyone in the world can take online courses for free.
In partnership with several universities and organizations around the world, provides access to education, knowledge ... and an informed society is a prepared society. In Coursera platform can attend physics courses, engineering, humanities, medicine, biology, social sciences, mathematics, business, computer science, and other subjects. Each course includes video lectures on different topics, questionnaires and has to perform a miniproject every week and submit them to the platform. To evaluate these works, called miniprojects, a peer review system is used. Although in some courses this system does not apply, courses like of humanities and social sciences.
The Coursera courses have a duration of approximately six to ten weeks, with about 2 hours of video lessons per week. Some courses still have a final project or an exam. Are provided forums for the courses and some students organize themselves and create meet-ups for asynchronous study. However, the Coursera Honor Code prohibits copying answers, so the discussion should not change answers, but should practice a healthy debate.



Gizmo 2.0 - Let's see what it is about

There very open source computers that have been marketed in recent times, having taken this market a big boost with the launch of the Raspberry PI board which sold lots of units worldwide. However, these computer graphics represent a negative factor. These boards have become popular with the release of the Raspberry Pi, which sold thousands of copies around the world, however, there are other products also open source, which is the case with Gizmo. Gizmo will launch soon its version 2.0 that you want to end up with basic graphics on computers and open source will have a retail price of around 199 US$. This single board can be used to electronic devices with large screens or even interactive systems to recognize images and gestures.

Augmented Reality

Very briefly, augmented reality is the combination of three-dimensional virtual reality objects, and allowing real-time interactivity.

To create an augmented reality system to serve a real object reference, a webcam and software to interpret the image is required. The object is placed in front of the camera, is interpreted by the software that generates in real time, the virtual element and the image is transmitted with the overlapping real and virtual element. In the image was added information hence the name Augmented Reality.
