Questions

GIS – Geographic Information GIS – Geographic Information System System

A computer based system for:

Capturing Storing Analyzing Querying Displaying Disseminatinggeographic data toprovide a snapshot of

reality.

GPS – Global Positioning SystemGPS – 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?What is Mobile GIS?

Mobile GIS is the use and collection of geographic data in the field on mobile

devices
