Ubiquitous GIS - Part IV Standards for UBGIS: ISO/TC211 WG 10 UPA (Ubiquitous Public Access) Fall 2007 Ki-Joune Li http://isel.cs.pnu.edu/~lik Pusan National University

Standards for Ubiquitous GIS Complex Integration of Divers Components Heterogeneity, Integration, and Interoperability Paradigm Shift to Ubiquitous Computing Environments Extension of Existing Standards Creation of New Standards

Two Aspects of Standards for Ubiquitous GIS GIS in Ubiquitous Computing Environments Ubiquitous Computing as H/W and S/W Infrastructures for GIS Ubiquitous GI Evolution of GI for Ubiquity Public Access

Standards for UBGIS in ISO/TC211 Creation of New Working Group Working Group 10: UPA (Ubiquitous Public Access) Goals GIS in Ubiquitous Computing GI for Ubiquity: Ease of Use and Public Access Efforts for GI Ease of Use Correct Description Generation

Related Standards of OGC: SWE WG in http://www. opengeospatial Goal of Sensor Web Enablement Working Group Quickly discover sensors (secure or public) that can meet my needs – location, observables, quality, ability to task Obtain sensor information in a standard encoding that is understandable by me and my software Readily access sensor observations in a common manner, and in a form specific to my needs Task sensors, when possible, to meet my specific needs Subscribe to and receive alerts when a sensor measures a particular phenomenon

Related Standards of OGC: SWE WG Specification for the integration of heterogeneous sensor webs SensorML: OpenGIS® Sensor Model Language SOS: OpenGIS® Sensor Observation Service SPS: OpenGIS® Sensor Planning Service TML: OpenGIS® Transducer Markup Language

OGC Sensor Web Enablement Sensor Web Enablement - Schema SensorML - models and schema for describing sensor characteristics for providing information for Discovery of sensors Location of sensors Processing of low-level sensor observations Listing of taskable properties On-demand processing of sensor observation Observation & Measurement - models and schema for encoding sensor observations

OGC Sensor Web Enablement Standard Web Service Interface Sensor Observation Service: Standard web Service Interface Requesting, filtering and retrieving observations Sensor Planning Service: Standard web Service Interface User-Driven acquisitions and observations Web Notification Service: asynchronous notification of sensor events (tasks, observation of phenomena) Sensor Registries: discovery of sensors and sensor data
