Questions
GIS – Geographic Information System
A computer based system for:
 Capturing
 Storing
 Analyzing
 Querying
 Displaying
 Disseminating
geographic data to
provide a snapshot of reality.
GPS – Global Positioning System
•GPS
is a worldwide radio-navigation
system formed from a constellation of
24 satellites and their ground stations.
•GPS
uses these "man-made stars" as
reference points to calculate positions
accurate to a matter of meters or even
centimeters with certain units
•In
a sense it's like giving every square
meter on the planet a unique address.
What is Mobile GIS?
Mobile GIS is the use and collection of
geographic data in the field on mobile
devices
