Satellite imagery would be most useful in a. calculating urban growth b. determining exact location c. measuring elevation d. navigating between places

A satellite image is a visual representation of the information captured by a sensor (normally an optical sensor, but there are different types of sensors) placed on an artificial satellite for that purpose.

In the case of optical sensors (depending on their type) they collect the information reflected by the surface of the Earth that is then sent back to it and is conveniently processed by a specialized team.

In this context, satellite imagery is useful for diverse purposes, but one of the most used is for calculating urban growth. For example, having various images of the same place in different times, we will be able to observe the changes there.

Because for determining exact location and navigating between places, although satellite imagery is useful, is better to use the GPS (Global Positioning System using other type of satellites) and for the task of measuring elevation, this will depend on the type of sensors in the satellite.
