What is remote sensing and what are some ways mapping data can be gathered remotely?
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.

Why would amapmarker use active remote sensing instead of passive remote sensing?
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.
What is the role of electromagnetic radiatin in remote sensing?
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.
What are some of the types of information collected by remote sensing?
Remote sensing can collect various types of information, such as land cover, land use, vegetation health, topography, temperature, precipitation, and pollution levels. This data is often used for mapping, monitoring environmental changes, assessing natural disasters, and managing natural resources.
What is the opposite from remote sensing?
The opposite of remote sensing is close-up sensing, where data is collected from objects or phenomena in close proximity to the sensor or observer. This type of sensing involves direct contact or nearness to the subject being observed, as opposed to remote sensing which involves collecting data from a distance.
What are the four types of remote sensing?
The four types of remote sensing are passive remote sensing (detects natural radiation), active remote sensing (emits energy and measures its reflection), aerial photography (uses cameras on aircraft or satellites), and satellite imaging (capturing images from space using satellites).
What is remote sensing and what are some ways mapping data be gathered remotely?
Remote sensing is the process of collecting data about an object or area from a distance, typically using satellites or aircraft. Some ways mapping data can be gathered remotely include satellite imagery, LiDAR (Light Detection and Ranging) technology, aerial photography, and drones equipped with sensors.

What does scientists do to collect data remotely?
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.
