How does spatial resolution in remote sensing relate to sensor function?

Spatial resolution in remote sensing is a critical factor that influences the detail and clarity of the images captured by sensors. When examining the relationship between spatial resolution and sensor function, the altitude of the aircraft and the sensor’s field of view play integral roles.

At higher altitudes, a sensor's field of view increases, allowing it to capture larger areas on the ground. However, the trade-off is that this wider view may reduce the level of detail in the captured imagery, leading to a decrease in spatial resolution. Conversely, when flying at a lower altitude, the sensor captures a smaller area but at a higher spatial resolution, resulting in more detailed images.

Furthermore, the sensor's field of view can also impact spatial resolution. A wide field of view may encompass more ground area but will generally produce lower resolution images compared to a narrower field of view, which focuses on a smaller area and enhances detail.

Thus, the correct answer highlights that spatial resolution is indeed affected by both the sensor's field of view and altitude, making it essential to consider these factors when planning remote sensing missions to achieve the desired level of detail in the imagery.
