Uses: Directed Information Sources
• iTriage- iPhone application
– integrates clinical information
with geolocational data
– designed to empower patients
to make better health
decisions
– get appropriate help, whether
in emergency or preparing for
routine surgery

Newer Uses
• Geolocation monitoring (individual patients)
– for wandering patients,
– in the elderly remote monitoring (vital signs) -
promoting autonomy
– can detect falls
• Geolocational tagging in emergency and
disasters (for triage) and mass casualty
situations

Social Media
• Ambient geospatial information as location
and time recorded
• Use of Twitter for infoveillance/infodemiology
– provides various types of location data, including
exact GPS coordinates
– but limitations as not well understood /or
documented
– Good real time data and low costs
excellent for public health
