Software: GIS software analyses data and presents it in different combinations for the user.are collected and entered into the GIS software Data: geospatial information (where things are located) and the details of objects such as services, roads, buildings etc.People: people who use GIS are professionals who have been educated to use GIS and have made a career out of working with GIS.plan for the future, for example which parts of the high country have undergone tenure review.GIS gives people in these organisations graphical representations of data that allows them to: GIS is used by organisations, such as city councils, that need access to data and need to be able to combine different data sets together. This system of modern mapping is called GIS – Geographic Information Systems. Modern maps are created using special software that combines lots of different sorts of information. Maps have come a long way since people first began drawings to show where they were.

How do you think GPS is used in the high country? What is GIS Tectonics: enables fault motion measurement in earthquakes.

Surveying: Surveyors use absolute locations to make maps and determine property boundaries.

Recreation: For example, geocaching and waymarking.

Personal Locator Beacons (PLB): used to inform search and rescue authorities of your exact location in the event of an emergency.

The device uses voice activation to describe a preferred route based on the position of the receiver, the position of the destination and a street map

Bus stops: to show how long the bus will take to arrive at a bus stop.

Bus tour commentary: your location will determine what information is displayed about approaching points of interest.

Geotagging: Applying location coordinates to digital objects such as photographs and other documents for purposes such as creating map overlays.

Pets can be chipped so they can be found if they become lost

Tracking a vehicle, person, pet or aircraft: Receivers provide continuous tracking and can provide an alert if the receiver leaves a set area.

Disaster relief and emergency services: Depend upon GPS for location.

This technology can be used for things like automatic updates of daylight saving times on cell phones

Clock synchronization: The GPS time signals use highly accurate atomic clocks.

Watch this Youtube video to find out more about how GPS works. When the receiver estimates the distance to at least four GPS satellites, it can calculate its position in latitude, longitude and height. The distance to the GPS satellites can be calculated by estimating the amount of time it takes for their signals to reach the receiver.

The signals move at the speed of light and arrive at a GPS receiver at slightly different times because some satellites are further away than others. All GPS satellites transmit at the same instant. Receivers require a clear view of the sky, so they are only used outdoors and do not perform well in forests or near tall buildings.Įach GPS satellite has an atomic clock and sends a signal stating its location and the exact time. Global Positioning System satellites transmit signals to GPS receivers on the ground. A GPS unit is actually a receiver that collects signals from satellites. GPS Stands for Global Positioning Systems and they are now used throughout the world.
