ISO 19116 Positioning Services

• Interfacing Positioning Service to GIS
• Position data transfer operations
• System control operations
• Technology Neutral
• Generic positioning information segregated from
  technology specific
• Extensible
• New technologies
• New operations

Positioning Service Connects Technology to Users
5
ISO 19116 Positioning Services

• Positioning interface for wide range of uses
• Low mobility -- static site coordinates
• High mobility -- in-vehicle navigation
• Low detail -- transient coordinate display
• High detail -- geodetic survey observation
• Simple user controls -- mobile telephone
• Sophisticated user control -- GIS data collection
• Simple location structure -- 2D static
• Detailed location structure -- T, 3D, motion,
  orientation

6
ISO 19116 Positioning Services

• Provides interface for wide range of technologies
• GNSS (GPS, Glonass, Galileo)
• Optical (Total Station, Laser Rangefinder)
• Inertial (INS or GNSS augmented INS)
• Terrestrial RF (cellular and PCS locators)
• Dead Reckoning (Odometer and compass)

7
ISO 19116 Positioning Services

• Object Oriented Design
• Data Content Oriented Class Structure
• Observation
• Time tag, Position, Motion, Orientation
• Observation Quality
• Mode of operation
• Positioning Method
• Coordinate Reference System
• Quality Evaluation Method

8
ISO 19116 Positioning Services

• Main Building Blocks
• Observation Information
• Generic
• Time tag, Position, Motion, Orientation
• Technology Specific
• Operating Conditions, Performance Indicators
• System Information
• Session Information

Positioning Service Provides Operations Enabling
User to Access Location Data
11
ISO 19116 Positioning Services

• Requirements can be fulfilled in several ways
• Transmission of full detail
• client obtains all needed information from
  service
• Client employs local detail
• transmission reduced to essential elements
• e.g. transmit position updates only
• coordinate system pre-defined
• time reference pre-defined
• quality evaluation procedures pre-defined

12
ISO 19116 Positioning Services

• Flexible Object Model
• Multi-use
• Multi-technology
• Scalable Implementation
• Selectable data rate
• Selectable level of complexity
• Extensible Structure
• Open to new positioning technologies
• Open to add new operations

13
