​​In terms of GIS, what do balloons, pigeons, airplanes, and satellites have in common?(1 point)

Responses

​They have all been a part of GIS since the 19th century.

​They have all been part of the evolution of aerial photography, which is central to modern GIS.

​​They have all been part of modern drone development.

​They have all been flown by geologists.

​They have all been part of the evolution of aerial photography, which is central to modern GIS.

The correct answer is:

They have all been part of the evolution of aerial photography, which is central to modern GIS.

In terms of GIS (Geographic Information System), the correct answer is:

​They have all been part of the evolution of aerial photography, which is central to modern GIS.

To understand why this is the correct answer, let's break down the options:

1. They have all been a part of GIS since the 19th century: This option is incorrect because while satellites have been used in GIS since the 1970s, balloons, pigeons, and airplanes were not commonly or extensively used in GIS until the 20th century.

2. They have all been part of the evolution of aerial photography, which is central to modern GIS: This option is correct. Aerial photography, which involves capturing images of the Earth's surface from an elevated position, has been a crucial component of GIS since its early stages. Balloons, pigeons (in the early days), airplanes, and satellites have all been used to collect aerial imagery that is essential for creating accurate maps, analyzing landscapes, and extracting geographic information.

3. They have all been part of modern drone development: This option is incorrect because while balloons, pigeons, airplanes, and satellites have all influenced various aspects of modern drone development, they are not solely tied to it. Drones have emerged as a distinct technology in recent years.

4. They have all been flown by geologists: This option is incorrect as all of the mentioned technologies have been utilized by various professionals, not just geologists. Additionally, aerial technologies are not exclusive to geologists but are widely used across different fields like urban planning, environmental monitoring, disaster response, and more.

In conclusion, the correct answer is that balloons, pigeons, airplanes, and satellites have all been part of the evolution of aerial photography, which is central to modern GIS.
