Question 9

Answer 9

Any softwaare/hardware that interacts with real-world locations. Use of this is the basis of many geographers work practices:

For example the Global Navigation Satellite System (GNSS): network of satellites that circle the earth, beaming information on their location down to out planet. Identifies any time or weather in a specific location. Calculate speed, bearing, distance, tracking etc.

Question 10
