BIG GEO DATA (now) !
#gimaday
Get BIG geo data! The data explosion has enabled GIS on the Web to grow into new application areas. The Internet of Things, the Sensorweb and open data repositories are leading us into an era of big geodata. Apart from the amount of data, the role of data in GIS and our concept of data are also changing. This presentation explains a few of these developments. It calls for students to pay closer attention to the data aspect of GIS and to gain experience with big geodata. The presentation ends with a few tips for (eternal) students.

BIG DATA WHAT IT IS ABOUT
Guide us to different insights about our world
Why? Lower costs. Improved decision making. Innovation of products and services.

Sensing the City
The main dataset used in this research is the sensed data retrieved by van der Hoeven and Wandl (2015) for the ‘Hotterdam’ project. In the summer of 2014, they measured the temperature in Rotterdam by using sensors. About 1300 sensors were distributed.
