The spatial resolution of a sensor can be defined as the area of ground imaged by one pixel. High spatial resolution means each pixel represents a small square of ground, so it is easy to identify tiny features in an image. Spectral resolution is the width of the regions of the electromagnetic spectrum that a sensor will detect. High spectral resolution allows material identification through a characterization of its spectrum.
Spatial resolution refers to the ability of a sensor to distinguish between objects in an image based on their size or distance from one another, while spectral resolution refers to the ability of a sensor to distinguish between different wavelengths or colors within the electromagnetic spectrum. In other words, spatial resolution relates to the clarity or level of detail in an image, while spectral resolution relates to the ability to differentiate between different spectral bands.

What are the differences between spatial and temporal resolution?
Spatial resolution refers to the level of detail in an image or data based on the size of each pixel or grid cell, while temporal resolution refers to the frequency at which new data is collected or updated in time. In other words, spatial resolution relates to the clarity of the image, while temporal resolution relates to how often that image is updated or refreshed.
How many bands of data are in a panchromatic image?
A panchromatic image typically consists of a single band of data, capturing light across a broad spectrum. This band combines all visible wavelengths into a grayscale image, offering high spatial resolution but limited spectral information.
What is the significance of the distance between the two dishes in a radio interferometer with two dishes?
The distance between the two dishes in a radio interferometer is significant because it determines the resolution and sensitivity of the instrument. A larger distance between the dishes allows for higher resolution and the ability to detect fainter signals from celestial objects. This is important in radio astronomy for studying the fine details of distant objects in space.
How do you say spaceship in french?
In French, spaceship is "vaisseau spatial."
What spatial bodies found between fourth and fifth planet?
The spatial bodies found between the fourth planet (Mars) and the fifth planet (Jupiter) in our solar system are the asteroid belt, a region filled with millions of rocky objects that vary in size from small pebbles to large protoplanets.
Why both high spatial and spectral resolution can't be achieved at same time?
Achieving both high spatial and spectral resolution simultaneously is challenging because increasing one often comes at the expense of the other due to limitations in sensor technology and data processing capabilities. Increasing spatial resolution may require larger sensor arrays and computational power, which can impact the ability to collect and analyze detailed spectral information simultaneously. Balancing these trade-offs is a key consideration in designing remote sensing systems.
What are the differences between spatial and temporal resolution?

What is the ability to distinguish between two nearby objects?
Resolving power.
Does the diameter of the laser beam affect the spatial resolution of the CR imaging system?
Yes, the diameter of the laser beam can affect the spatial resolution of the CR imaging system. A smaller diameter laser beam can provide higher spatial resolution by focusing the laser energy more precisely on the imaging plate, resulting in sharper images. However, other factors such as detector resolution and plate phosphor characteristics also play significant roles in determining spatial resolution.
Do CT scans provide a much higher resolution of anatomical detail than do MRI scans?
As we know,Clarity of the image is decided by its Spatial Resolution but not by Pixel Resolution. CT have high Spatial Resolution but MRI have comparable Spatial Resolution to CT&far better Contrast Resolution than CT-So,MRI is the BEST to demonstrate Anatomy,especially in parts containing more soft tissue[Eg:Brain]&CT is the BEST to demonstrate Bony Anatomy.
What the relationship between spatial pattern and spatial process?
there is a reciprocal relationship between the spatial pattern and the spatial process.
Measure of clarity of an image?
For practical purposes the clarity of the image is decided by its spatial resolution, not the number of pixels in an image. In effect, spatial resolution refers to the number of independent pixel values per unit length.
How many bands of data are in a panchromatic image?
A panchromatic image typically consists of a single band of data, capturing light across a broad spectrum. This band combines all visible wavelengths into a grayscale image, offering high spatial resolution but limited spectral information.
What do you mean spatial resolution of gamma camera in nuclear medicine?
the minimum distance between two points . measured by gamma camera ;ANSWEARED BY ANBRIN KULSOOM
What is the difference between spacial and spatial?
"Spacial" is a misspelling of "spatial," which refers to relating to space or the physical dimensions of an object or area. They have the same meaning, but "spatial" is the correct spelling.
What is the Importance of spatial resolution in remote sensing?
Spatial resolution in remote sensing refers to the level of detail captured in an image. A higher spatial resolution means better ability to distinguish features on the Earth's surface, allowing for more precise identification and analysis of objects. This is essential for applications such as land cover mapping, urban planning, and environmental monitoring.
Spatial resolution of modern CT scanners?
Modern CT scanners typically have a spatial resolution ranging from 0.5 to 1 mm, which means they can visualize structures down to that size. Some advanced systems can achieve even higher spatial resolutions, allowing for detailed imaging of small structures within the body.
