Your Welcome
need an answer for test!
Bro...i need an answer for this test...
I need answer please hello
mmm me to
Yes PewDiePie, I am using the Connexus platform and this is a question on the Unit 4 Unit Test.
The correct answer is B. By using topographic maps.
Global Positioning Systems (GPS) use elevation points on Earth's system to find latitude and longitude by leveraging topographic maps. Topographic maps provide detailed information about the elevation or relief of the Earth's surface, including the hills, valleys, cliffs, and other physical features.
GPS devices receive signals from a network of satellites to determine the user's precise location on the Earth's surface. These signals provide information about the distance between the GPS device and multiple satellites. By using the concept of trilateration, which involves measuring the distance to at least three satellites, the GPS receiver can calculate its latitude and longitude coordinates.
While satellite images and photography can provide valuable visual information for navigation and mapping purposes, they do not directly provide elevation points needed for determining latitude and longitude. Therefore, options C and D are not correct for this particular question.
So, the correct option is B – By using topographic maps.
