IoT Meets Geo
The Open Geospatial Consortium (OGC) is a non-profit organization facilitating the development of geospatial standards, with over 470 members and 40 established standards since 1994. The document discusses the integration of IoT with geospatial data, highlighting its potential for enhanced situational awareness and data visualization through standardization. It emphasizes the arrival of IoT as accessible and practical, along with OGC's Sensor Web Enablement standards that support the discovery and tasking of sensor assets.

OGC ® Why Geo? • Whatis IoT? – abstracting real-world phenomena into data streams – combining these data to create synergistic insights, especially based on nearness (contextual awareness) – visualizing the results • This is GIS! © 2014 Open Geospatial Consortium McHarg’s method involved superimposing layers of geographical data (e.g. environmental and social factors) so that their spatial intersection (relationships) can be used in making land use decisions. This core idea, McHarg’s planning methodology, lead to the development of Geographic Information System (GIS) software tools.

OGC ® IoT is finallyarriving: it’s bubbling up from the grassroots. • IoT: long-prophesied phenomenon of everyday devices talking to one another — and us — online – Back in the ’90s, big companies built systems to do tricks like this, but they were expensive, hard to use, and vendor-specific. • Hackers now using increasingly inexpensive sensors and open source hardware, add intelligence to ordinary objects. – Sensor prices going down; sizes going down. Only limit is your imagination. – Cloud services – “If This Then That” or Cosm - let devices interact in unexpected ways • IoT has reached the “Apple II stage” – when a new technology finally becomes easy enough to use that thousands of people start using it. http://www.wired.com/opinion/2012/12/20-12-st_thompson/ © 2014 Open Geospatial Consortium
