In terms of GIS, what do balloons, pigeons, airplanes, and satellites have in common? (1 point) They have all been a part of GIS since the 19th century They have all been part of modern drone development They have all been part of the evolution of aerial photography, which is central to modern GIS They have all been flown by geologists
They have all been part of the evolution of aerial photography, which is central to modern GIS
In terms of GIS, balloons, pigeons, airplanes, and satellites have all been part of the evolution of aerial photography, which is central to modern GIS. (1 point)
The correct answer is: They have all been part of the evolution of aerial photography, which is central to modern GIS.
To arrive at this answer, you can break down the question and analyze each option:
- Option 1: They have all been a part of GIS since the 19th century
This statement is incorrect. While GIS (Geographic Information Systems) has evolved over time, the use of balloons, pigeons, airplanes, and satellites in GIS did not start in the 19th century.
- Option 2: They have all been part of modern drone development
This statement is partially correct but not the best answer. Drones have become an important tool in GIS in recent years, but not all the mentioned methods (balloons, pigeons, airplanes, and satellites) are related to drone development.
- Option 3: They have all been part of the evolution of aerial photography, which is central to modern GIS
This statement is the most accurate answer. Aerial photography has played a crucial role in the development of GIS. Balloons, pigeons (historically used as messengers to carry cameras), airplanes, and satellites have all been used to capture aerial imagery, which is essential for collecting geospatial data and creating accurate maps in GIS.
- Option 4: They have all been flown by geologists
This statement is not accurate. While geologists may use some of these methods for specific purposes, it does not encompass the common use of balloons, pigeons, airplanes, and satellites for aerial photography in GIS.
Therefore, option 3, "They have all been part of the evolution of aerial photography, which is central to modern GIS," is the correct answer.
