Title: ISOTC 211 Geographic Information Geomatics


1
ISO/TC 211 Geographic Information / Geomatics
  • WI 16 - Positioning Services
  • ISO CD 19116
  • presented to
  • Joint Steering Group on Spatial Standardization
    and Interoperability
  • by
  • Thad Mauney, Ph.D.
  • Spatial Systems
  • tmauney_at_wtp.net 1-406-256-2033

2
ISO TC 211
  • Standards Include
  • Positioning
  • Metadata
  • Data Quality
  • Spatial Reference System
  • Temporal Reference System
  • Feature Cataloguing
  • Portrayal

3
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

4
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
  • Quality Information

9
ISO 19116 Positioning Services Classes
10
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
TC/211 Standards Are Supportive of Location Based
Services
  • Current Work Items
  • Spatial Ref by Coord.
  • Spatial Ref by Ident.
  • Metadata
  • Spatial Temporal Schemas
  • Geospatial Services
  • Positioning Services
  • Portrayal Services
  • SQL SFA Extension
  • Geodetic Codes Par.
  • Potentially Needed
  • Source Search Service
  • Service Selection Service
  • Spatial Search Service
  • Data Delivery Service
  • Coord. Transform. Service
  • Reference Transl. Service
  • Route Calculation Service
  • Message Relay Service
  • Event Alert Service
  • Object Location Query Serv.

14
Other IT Services Likely Required by LBS--
shared and standardized with other information
technologies
  • Communication
  • Subscriber Management
  • Purchase / Payment Management
  • Privacy Management
  • Source Authentication
