Why is ground truthing important?
Ground truthing is important because it involves physically verifying data or information collected through remote sensing or other indirect methods. This helps ensure the accuracy and reliability of the data by comparing it to actual conditions on the ground. Ground truthing is especially valuable in fields like environmental science, disaster response, and urban planning where precise and reliable data is crucial for decision-making.
In addition to using data from remote sensing cartographers gets data to make maps from?
In addition to remote sensing data, cartographers also use ground surveys, GPS technology, aerial photography, and geographic information systems (GIS) to collect data for making maps. These methods help ensure accuracy and provide additional layers of information that can be used for mapping purposes.
What technological advances have helped geographers study the earth?
The development of ground-penetrating radar has been of great assistance to archaeologists, as well as geologists.
How did remote sensing change the way geographic data were obtained?
Remote sensing allowed for the collection of geographic data without physically being on the ground. This technology enables the capture of information about the Earth's surface from a distance, using satellites, drones, or aircraft. Remote sensing has made it possible to gather data over large areas quickly and efficiently, revolutionizing the way geographic data are obtained.
How a seismograph looks like?
A seismograph typically consists of a drum or digital display connected to a sensing device that records ground vibrations caused by earthquakes. The sensing device, typically a pendulum or mass on a spring, produces a trace on the paper or screen to show the intensity and duration of the seismic waves. Modern seismographs can also use electronic sensors to capture seismic data digitally.
What are some methods of remote sensing?
ground surveying
Can a snake hear?
A snake "hears" by sensing vibrations in the ground.
Why does a cactus planted in the ground outdoors will need more water than a cactus in a pot inside?
inside the weather conditions are more controlled than outside. the cactus usually get larger outside
How can scientists best verify the accuracy of remote sensing data?

What has the author Christopher J Brooke written?
Christopher J. Brooke has written: 'Ground-based remote sensing'
What are the differences between ground based research methods and remote sensing research methods?
In remote sensing, aircraft or satellites provide the platforms for sensing applications. The primary difference is that in the remote sensing methods, a lot more area can becovered in a very short period of time than with ground-based methods. There are details that cannot be resolved by the remote methods that can be determined on the ground, but there are trade offs with the two methods of investigation. More and more sophisticated way of "looking" at the ground from remote platforms continue to be developed. The location of South American temples hidden in the jungle is just one example of the capability of the remote platform.
How many sensing devices are in a modern seismograph?
A modern seismograph typically consists of multiple sensing devices, called seismometers or accelerometers, which are strategically placed to detect ground motion caused by seismic waves. The number of sensing devices can vary depending on the configuration and sensitivity required for the specific application.
What is a good sentence for ground truthing?
Ground Truthing is used to verify Remote sensing and is also known as HUMINT, or human intelligence.
Where can you find stones?
outside in the ground
What are some of the types of information obtained by remote sensing?
Remote sensing is the examination or the gathering of information about a place from a distance. Such examination can occur with devices (e.g. - cameras) based on the ground, and/or sensors or cameras based on ships, aircraft, satellites, or other spacecraft.
Are smooth muscles voluntary or involuntary?
it is involuntary and is controlled by autonomic ground plexus.smooth muscle is found on wall of organs.
