Why do geographers rely on satellites. When you were lost. Geographers analyze new markets and locations for businesses. Why do geographers rely heavily on satellites to gather geographic data. Geographers rely on geographic information systems software or gis and satellite imagery to collect data they need for their reports.

When might you use gps if it were availableto you. It uses many sources of information. Geographers assess the impacts of rising sea levels melting glaciers and tropical storms while others study impacts of wildfires or manage wetlands. Imaging satellites can measure the changing sizes of glaciers which is difficult to do from the ground due to the remoteness and darkness of the polar regions.

In the past they would have had to traverse the earth to map all of it. Satellites can accurately photograph the entire earth in a short time. Satellites can quickly pick up data from large areas. For example using satellite imagery a human geographer might research the impact of conflict on a region its effects on water supply farming practices and emigration.

Data acquired by satellite borne radars were able to show sea levels have been rising by three mm a year over the last decade. Why is gis potentially more useful to geographers than satellites. Satellites monitor ocean temperatures and prevailing currents.
