Motivation

• Present Web good at describing Conceptual space
• Show me Chinese Restaurants within 5 miles
• Eg. yahoo.com
• Spatial Web describes both Conceptual Physical
  space
• Find the closest Chinese Restaurant with the
  minimum waiting time
• Inform me whenever this freeway becomes
  congested within two miles or less

Design Goals

• Novel information infrastructure to obtain,
  manage deliver spatially-constrained data
• Information resides at the physical location
  where it is produced
• Information sources can have unbounded
  heterogeneity
• as simple as embedded sensor devices
• as complex as full-scale databases

How Spatial Web differs from Todays Web

• All Spatial web pages have a limited physical
  DataScope 
• Links between the Spatial Web pages mirror the
  relevant structure in the physical space

Architectural components
Pervasive Sensor Networks

• Pervasive Sensor Networks forming a WebDust of
  information
• InfoDispensers
• Data aggregation distribution devices that
  blanket the physical landscape and act as
  information-sprinklers
• Sprinke important local information on users as
  they pass nearby

7
Spatial Crawling Potential Application

• Using space as an index to search for local data
• Link structure to navigate through physical space
• Current Prototype
