WG.20A-TECHNOLOGY-GPS-GIS-INTERNET

What is the difference between GPS and GIS? (WG.20A)

• A.GPS uses GIS data

• A.GIS uses GPS data to determine location

• A.GPS is the layering of data, whereas GIS is the gathering of data.

• A.GIS is the layering of data, whereas GPS is the gathering of data.

A city wants to determine the best location for a landfill. It is creating a composite map based on a terrain map, a land-use map, a road map, and 3-D images of groundwater reservoirs.

What technology is it relying on to create the composite map?

• the Internet

• Global Positioning System

• Geographic Information Systems

• Geostationary Operational Environmental Satellites

Geographic information system (GIS) technology can be used to — (WG.20A)

• find wreckage of a plane crash

• analyze data for decisions on future land use

• find directions from one place to another

• take topographic pictures from space

Which of the following has been a useful benefit of Global Positioning System (GPS) technology? (WG.20A)

• GPS can store large amounts of digitalized data for emergency situations.

• Consumers can use GPS to navigate their cars when traveling.

• GPS can prevent cars and trucks from having road accidents.

• GPS has made it easier for countries to desalinate sea water.

One limitation of geospatial technology is that it cannot provide information about (WG.20A)

• Things below the surface

• Why humans do things

• The impact of industry

• Areas humans cannot safely visit.

Which statement about the Global Positioning System (GPS) describes an application of this technology? (WG.20A)

• A GPS receiver can determine the location of resources needed for networking capabilities.

• Correct use of GPS technology allows people to build in uninhabitable regions.

• International compliance with GPS readings can increase trade opportunities.

• A GPS receiver can improve the safety of commercial transportation.

How has the expansion of the internet significantly affected the global economy? (WG.20A)

• by decreasing business competition

• by increasing consumer choice

• by decreasing specialization opportunities

• by increasing protective tariffs

Which statement is supported by these survey results (WG.20A?

• People depend on traditional information sources more than new technologies.

• Technological progress has begun changing the way people learn about current events.

• Technology has decreased participation in resolving important community issues.

• People in different age groups disagree on the usefulness of new technologies.

Which is the main purpose for global positioning (GPS) technology? (WG.20A)

• To determine relative locations on Earth

• To determine absolute locations on Earth

• To determine elevations of geographic features on Earth

• To determine the physical characteristics of regions
