Which type of information is NOT typically associated with remote sensing?

Remote sensing involves the acquisition of data about an object or phenomenon without making physical contact. It primarily focuses on capturing various forms of information using sensors that detect electromagnetic radiation reflected or emitted from the Earth's surface.

When we consider the types of information typically gathered through remote sensing, temperature gradients, soil composition, and surface features are all characteristics that can be analyzed through various remote sensing techniques. For instance, satellite imagery can detect surface temperature through thermal infrared sensors, analyze soil moisture and composition using microwave sensors, and map surface features through optical and radar imaging.

Distance to travel, on the other hand, is not a direct type of information gathered through remote sensing. Instead, distance typically relates to measurements or calculations derived from known data, like the location of remote sensing data points, rather than being a feature inherently captured by remote sensing technology. Hence, it does not fit within the scope of typical remote sensing applications.
