Are remote sensing satellites restricted by the us gov?
Yes, remote sensing satellites operated by U.S. entities are regulated by the U.S. government through the National Oceanic and Atmospheric Administration (NOAA) and the National Reconnaissance Office (NRO). These regulations control the resolution and dissemination of images to protect national security and privacy concerns.
How can a satellite see through clouds?
Satellites can see through clouds using active microwave remote sensing technology. Microwaves can penetrate clouds, allowing satellites to observe Earth's surface even when it is obscured by clouds. By measuring the microwave signals that are reflected or emitted from the surface, satellites can create images and gather data despite cloud cover.
What are thousands of tiny dots that make satellites images called?
pixels
Why are concave mirrors useful for satellites?
Concave mirrors focus light on a specific point. That can increase the concentration of sun light on solar panels. Concave antennae are used to aim radio waves, as well as collect them and focus them on a receiver.
How do satellites send images and data back from space?
Satellites send images and data back to Earth using radio waves. The satellite collects the information with its sensors and cameras, processes it, and then transmits it to ground stations on Earth. The ground stations receive the data and images, often through large antennas that are pointed at the satellite as it passes overhead.
What is relatively new field in which satellites images are used to study the surface of the earth?
remote sensing
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 term for the process of gathering information through images taken at a distance?
The term for gathering information through images taken at a distance is remote sensing. This technique involves using sensors to collect data from a target without physically touching it, often done from aircraft or satellites.

What are three types of remote sensing?
Three types of remote sensing are passive remote sensing (detects natural radiation emitted or reflected by objects), active remote sensing (sends out its own radiation to illuminate objects), and aerial photography (capturing images of the Earth's surface from aircraft or satellites).
Are remote sensing satellites restricted by the us gov?
Yes, remote sensing satellites operated by U.S. entities are regulated by the U.S. government through the National Oceanic and Atmospheric Administration (NOAA) and the National Reconnaissance Office (NRO). These regulations control the resolution and dissemination of images to protect national security and privacy concerns.
How is satellite land survey done?
Satellite land surveying uses remote sensing technology to capture images of the Earth's surface from satellites orbiting above. These images are processed to create detailed maps and measurements of the land, which can be used for various purposes such as urban planning, agriculture, and environmental monitoring. The data collected from satellite land surveys can provide valuable information about the terrain, vegetation cover, and land use patterns over large areas.
Are satellite images based on data obtained by land sat satellites?
Yes, satellite images based on data obtained by land sat satellites.
What has the author Maurice J Grolier written?
Maurice J. Grolier has written: 'The environment of south-central Tunisia as observed on Landsat scene 206/036' -- subject(s): Remote sensing 'A qualitative appraisal of the hydrology of the Yemen Arab Republic from Landsat images' -- subject(s): Hydrology, Landsat satellites, Remote sensing
What are some tools used for remote sensing?
Some tools used for remote sensing include satellites, drones, LiDAR (Light Detection and Ranging) systems, and ground-based sensors. These tools can capture various types of data such as images, terrain elevation, and spectral information for monitoring and analyzing the Earth's surface and atmosphere from a distance.
