The OGC Interoperability Program (IP)
• A global, collaborative, hands-on engineering, prototyping
and testing designed to rapidly deliver
– Candidate standards
– “Demonstratable” implementations
– Engineering Reports
• Sponsors and Participants work together.
– Sponsors provide requirements, use / business cases and funding
– Participants work with sponsors to define and/or refine standards to solve a
given interoperability problem

Carl’s Prediction
• In the years to come, the vast majority of location enabled
content will be generated (sensed) by a staggering array of
sensor platforms, including mobile, dynamic, and in-situ
sensors
– Cell phones and other location enabled mobile devices
– The very infrastructure of the internet (location enabled DHCP and
SIP)
– Satellites, UAV’s, traffic, roadside, weather, oceans, video, and on
and on and on

OGC Sensor Web Enablement (SWE)
• Define, test, document and approve standards that:
– Define interfaces for sensor access and tasking
– Define metadata encodings
• To enable real time integration of heterogeneous sensor
webs into the information infrastructure.
• Developers use these standards to
– Deploy applications, platforms, and products that integrate Webconnected devices such as flood gauges, air pollution monitors,
stress gauges on bridges, mobile heart monitors, Webcams, and
robots as well as space and airborne earth imaging devices.

SWE Standards Baseline
• Observations & Measurements (O&M) - Standard
models and XML Schema for encoding observations and
measurements from a sensor, both archived and real-time.
• Sensor Model Language (SensorML) - Standard models
and XML Schema for describing sensors systems and
processes associated with sensor observations
• Transducer Model Language (TransducerML or TML) The conceptual model and XML Schema for describing
transducers and supporting real-time streaming of data to
and from sensor systems.

SWE Standards Baseline
• Sensor Observations Service (SOS) - Standard web
service interface for requesting, filtering, and retrieving
observations and sensor system information.
• Sensor Planning Service (SPS) - Standard web service
interface for requesting user-driven acquisitions and
observations.
• Sensor Alert Service (SAS) - Standard web service
interface for publishing and subscribing to alerts from

Geo-Referencing Workflow Overview
• Requirements:
– Demonstrate a standardized workflow to allow the user to
interactively access a subset pixels from a coverage service stored
in the compressed domain (JPEG2000) and preserve the image
relationship with the associated 'sensor model' parameters such that
precise geopositioning capabilities can be realized in a dynamic,
interactive, networked environment.
• Participants:
– PCI, ITT, SPOT, GMU, IFGI, UAH

GeoRef Process – Approach
• The process is built using WS-BPEL
• The process is invoked as a Web Service
• The services within the process are invoked using SOAP
bindings

Components
• There are 6 Web Services used in the GeoRef Process:
– SPS(SPOT)
• Schedules and implements a sensor task
– SOS(SPOT)
• Provides raw imagery as JP2K or GeoTIFF
– FTP2JPIP(GMU)/JPIP(ITT)
• Ingests the raw imagery to JPIP server using FTP
– WCS-T(PCI)
• Adds virtual JPIP coverage
– CSW(GMU)
• Registers WCS-T virtual JPIP coverage
– SAS(IfGI)
• Notifies users that new data is available.

Global Earth Observation System of Systems
(GEOSS) http://www.epa.gov/geoss/
• International Network that integrates remote sensing
data, other geospatial information, models and monitoring
data
“I am thrilled with the promise of GEOSS. It can provide us with better information to use in decision-making,
producing better decisions that are better informed with more data points. I hope to help make the promise of
GEOSS a reality.”
