Question

What is remote sensing? Describe the three remote sensing tools that geographers can use.

Please answer as soon as you can!

Answer 1

Answer:

Remote sensing is the science of obtaining information about objects or areas from a distance, typically from aircraft or satellites. ... Remote sensors can be either passive or active. Passive sensors respond to external stimuli. They record natural energy that is reflected or emitted from the Earth's surface.

Passive Sensors. Aerial Photography. FLIR. Geodetic Survey. Hyperspectral Imaging. Long-Wave Infrared. Multispectral Imaging. Near Infrared Surveys. Oblique Aerial & Ground Visible Band & Thermographic Imaging. Radiometrics. SWIR. Stereo Satellite Imagery.

Answer 2

Remote sensing is a science-based technique that enables data collection and body analysis without any physical interaction.

• Sectors like hydrology, geography, ecology, glaciology, oceanology, and geology heavily utilize this technique.
• To analyze and map the Earth's feature events, a tool called a geographic information system is used.
• Significant database processes, such as statistical analysis and query, are collected through the map using remote sensing and GIS technology.
• The GIS gathers data on various areas and provides tools for visualizing and analyzing it for the purposes of calculating population, economic development, and undergrowth.
• All of these features establish GIS as a standalone system that can be used for both private and public remote sensing applications.
• These programs are used to forecast and plan the results of satellites for remote sensing.
• Remote sensing tools include-

1. PCI

• The PCI Geomatics firm created Geomatica, a desktop remote sensing and photogrammetry software suite for processing earth observation data.  
• The main goal of Geomatica is to process data more quickly.
• Users can load satellite and aerial pictures to undertake advanced analysis.
• Many academic institutions and scientific initiatives throughout the world, like the GlobeSAR Program, have used Geomatica to study satellite imagery and trends.

2. "Earth Now" iPhone App

• Using data from Earth science satellites, NASA's Earth Now app for mobile devices visualizes recent global climate information, including surface air temperature, carbon dioxide, carbon monoxide, ozone, and water vapor concentrations as well as gravity and sea level changes.
• The Earth Science Communications Team at NASA's Jet Propulsion Laboratory created the project with assistance from NASA Headquarters.

3. 3D Visualization Software for Mission Science Operations (Viz)

• For planetary exploration mission science operations, the Viz package offers situational awareness, science analysis, and data comprehension capabilities.
• The technology combines network and plug-in interfaces with a 3D scene graph database and an interactive 3D viewer to provide a flexible and expandable visualization environment.
