 GPS – (Global Positioning System)
A device for measuring geographic coordinates at any
location on the earth.
 GIS – (Geographic Information System)
A database for maintaining and analyzing spatial
features and the relationships between features as they are
defined through geographic coordinates or measurements.

• GPS stands for Global Positioning System
• GPS is a satellite navigation system designed to
provide accurate position, velocity, and time
information almost anywhere in the world.
• The present system is known as NAVSTAR -
NAVigation Satellite Timing And Ranging.

6.  GPS was originally intended
for military applications, but in
the 1980s, the government
made the system available
for civilian use.
 GPS works in any weather
conditions, anywhere in the
world, 24 hours a day.

7. • Stands for Global Positioning System
• GPS is used to get an exact location on the surface of the earth, in three
dimensions.
• GPS is a very important data input source, used for surveying, military operations,
engineering, in mining, vehicle tracking, flight navigation, car navigation, ship
navigation, unmanned vehicle guidance, agriculture, and of course, mapping
• For mapping, a GPS tells us “where” and allows us to input “what”
• GPS is a worldwide radio-navigation system formed from 24 satellites and their
ground stations.
• Uses satellites in space as reference points for locations here on earth
• Ground stations help satellites determine their exact location in space.

8. • GPS derives position relative to satellite “reference
points,” using triangulation.
• The GPS unit on the ground figures out its distance to
each of several satellites using the time it takes for a
radio signal to travel to the satellite.
• To do this, the exact position of the satellites at a given
time, must be known; otherwise they can’t serve as
reference points.

11. • We need at least 3 satellites as reference points to
“triangulate” our position.
• Based on the principle that where we know our exact
distance from a satellite in space, we know we are
somewhere on the surface of an imaginary sphere with
radius equal to the distance to the satellite.
• With two satellites we know we are in the plane where the
two intersect. With three or more, we can get two possible
points, and one of those is usually impossible from a
practical standpoint and can be discarded

12. • The uses for GPS mapping are enormous. Here are just a
few examples:
• Centerlines of roads
• Hydrologic features (over time)
• Bird nest/colony locations (over time)
• Fire perimeters
• Geologic/mining maps

13. Geographic Information System

14. • A Geographic Information System, or GIS, integrates hardware, software,
and data for capturing, managing, analyzing, and displaying all forms of
geographically referenced information.
• GIS is a System of computer software, hardware and data, and personnel
to help manipulate, analyze and present information that is tied to a
spatial location –
• spatial location – usually a geographic location
• information – visualization of analysis of data
• system - linking software, hardware, data
• personnel – a thinking explorer who is key to the power of GIS-

15. • GIS is a spatial database with a strong visual
display component
• GIS is not primarily a mapping program
• GIS was developed in the early 1980s, but its
acceptance and development outside of the
environmental sciences has been slow
