OGC/ISO Standards: Baseline for Spatial Data Infrastructure

• ISO 19115: Metadata• Web Map Service (WMS) • Web Feature Service (WFS)• Web Coverage Service (WCS)• Web Map Context• Style Layer Descriptor (SLD)• Catalogue (CSW)• Geography Markup Language

(GML)• KML• Web Processing Service (WPS)

The GeoWeb is enabled by standards:

“The Geospatial Web is about the complete integration and use of location at all levels of the internet and the web.”

Why Geo?

• What is 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!

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.

IoT is finally arriving: 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/

OGC Sensor Web Enablement Standards

Enable discovery and tasking of sensor assets, and the access of sensor observations• Sensor Model Language (SensorML)

• Sensor Planning Service (SPS)

• Sensor Observation Service (SOS)

• PUCK

-- Complementary Standards --

• IEEE 1451 smart sensor standard

• OASIS (alert) standards

Large-scale Opportunistic Sensing

• Smartphones to be pocket seismometers – Right now, can detect earthquakes above Magnitude 5.0.

With better accelerometers in smartphones hope to detect smaller ones

– precious seconds' advance notice that a big trembler is on its way

• pressureNET – Global network of user-contributed atmospheric pressure

readings.– App displays data as markers on map and graphed over

time– To improve weather forecasting models.

• IoT devices measure Air quality (CO, NO2) – AirCasting - Air Quality Egg
