Remote sensing allows earth scientists to gather data about the Earth's surface and atmosphere from a distance. This data helps in monitoring changes in land cover, studying natural disasters, analyzing climate patterns, and detecting environmental issues like deforestation and pollution. Remote sensing also enables scientists to make predictions about future trends and inform decision-making for sustainable resource management.

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).
What can scientist study from remote sensing?
Scientists can study various Earth systems, including the atmosphere, oceans, and land surface, by analyzing remote sensing data. They can track environmental changes, monitor weather patterns, study land use and cover changes, detect natural disasters, and assess the health of ecosystems. Remote sensing provides valuable information to support scientific research, environmental management, and decision-making.
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.
Why do you need remote sensing?
Remote sensing is essential for studying and monitoring the Earth's surface, atmosphere, and oceans on a large scale. It allows scientists to gather data without physically being in the location of interest, helping to monitor environmental changes, natural disasters, and human activities. Remote sensing also plays a critical role in agriculture, urban planning, weather forecasting, and resource management.
What is remote sensing and GIS?
Remote sensing is the use of technology to gather information at a distance (i.e. without making contact with the object). For example weather radars that detect incoming rain fronts at a distance are a form of remote sensing. GIS is an acronym for geographical information systems. These are methods of compiling, sorting, analysing and presenting the geographical distribution of differing types of data. For example you could plot time variations in rainfall data against differing geographical locations.

What kind of data do field studies gather that remote sensing cannot gather?
There are a few field studies that sensing cannot put together. Some of the studies are space and earth.
What is wavelength in remote sensing?
Wavelength in remote sensing refers to the distance between two consecutive peaks or troughs of a wave. Different wavelengths of electromagnetic radiation, such as visible light, infrared, and microwaves, are used in remote sensing to gather information about Earth's surface and atmosphere. By analyzing the wavelengths of reflected or emitted radiation, scientists can infer valuable data about the environment being observed.
