Which of the following is a limitation of remote sensing?

Insufficient light can indeed degrade image quality in remote sensing. Remote sensing relies on capturing electromagnetic radiation, whether it's reflected or emitted from the Earth's surface, to create images and gather data about different areas. If the conditions do not allow for sufficient light, such as during nighttime or overcast weather, the ability of sensors to accurately capture images diminishes. This can lead to a lack of detail, color distortion, and an overall reduction in image clarity, making it difficult to extract meaningful information from the data.

In contrast, the other options present scenarios that do not accurately reflect the capabilities or limitations of remote sensing technology. Remote sensing is not limited to urban areas; it can be applied in rural, coastal, and even remote regions. Additionally, the idea that remote sensing has unlimited data storage capabilities is misleading, as storage is typically constrained by available technology and resources. Lastly, while remote sensing can complement ground sensors, it does not always engage or interact with them, as these are separate modalities of data collection.
