Remote sensing is the method of acquiring information about an object or phenomenon without coming into direct contact with it. Mapping data can be gathered remotely through techniques like satellite imagery, aerial photography, LiDAR (Light Detection and Ranging), and drones equipped with cameras or sensors. These methods enable the collection of data from a distance, allowing for the creation of detailed maps and models of the earth's surface.

A mapmaker might use active remote sensing over passive remote sensing because active remote sensing provides its own source of energy to illuminate the target, allowing for more control over the data collected. This can result in better resolution and accuracy in mapping features of interest.

Remote sensing is the small- or large-scaleacquisition of information of an object or phenomenon, by the use of either recording or real-time sensing device(s) to collect data in inaccessible areas etc.
Electromagnetic radiation is used in remote sensing to collect information about the Earth's surface and atmosphere. Different wavelengths of electromagnetic radiation interact with materials in unique ways, allowing scientists to identify and analyze various features and properties from a distance. By measuring the reflected or emitted radiation, remote sensing can provide valuable data for applications such as mapping, monitoring, and environmental assessment.
