What is the difference between spatial resolution and spectral resolution?
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.
What is the difference between sun synchronous polar orbit and a synchronous polar orbit?
A synchronous polar orbit satallite crosses the equator at the same time each day while the sun synchronous polar satellite appears in the sky at the same time every few days. the sun synchronous allow for greater temporal and spatial monitoring under same conditions and also have finer resolution as the polar synchronous imagery is at the continental scale.
Is sun coherent source?
Coherence is a measure of how well a signal, such as a optical wavefront, correlates with itself. For example, if you measure a peak at one point in space and time, what is the chance that you will measure a peak at another space and time? This hints that there are actually two forms of coherence, one related to time and the other to space.Temporal coherence looks at how well radiation measured at one single point correlates over time. In other words, if you measure a peak at one moment in time, how well can you predict that you'll measure a peak at another moment in time? Temporal coherence generally requires a small spread in wavelengths and a source which emits light in-phase. Lasers typically have high temporal coherence, while sunlight, which has a broad emission spectrum, has a low temporal coherence.But that's not the end of the answer.The other type of coherence is spatial coherence, and relates to how well two points on an emitter are correlated. One classic way of demonstrating spatial interference is the double-slit experiment: put two small slits in a sheet, and check to see that the light from the slits interferes constructively. Spatial coherence generally requires a small degree of angular spread. Again, most lasers have high spatial coherence. Sunlight also has high spatial coherence: because the sun is so far away, the rays of light are almost parallel.The coherence of sunlight has been studied since 1869 (Agarwal et al, "Coherence properties of sunlight", Optics Letters 29, p. 459, 2004) -- but even with more than a century of coherence, the subtle difference between spatial and temporal coherence can be tricky.
What spatial bodies found between fourth and fifth planet?
The asteroid Belt. http://en.wikipedia.org/wiki/Asteroid_belt
What is the adjective form of space?
It is spatial.
Difference between temporal redundancy and spatial redundancy?
The redundancy is nothing but the reduction.The temporal locality is of relating to short time requirements.And the spatial is of relating to over environment.The redundancy occur in the images are of most common,so many techniques applied to overcome this. In image temporal redundancy is of abrupt transitions while in spatial it is of block based transitions.Spatial is applied at minimum cost and temporal is at maximum cost.Threshold values apply to temporal redundancy and the pixel comparison technique applies to spatial redundancy.
What is the Difference between temporal mining and spatial mining?
spatial mining is the extraction of knowledge,spatial relationships and intresting measures that are not explicitly stored in spatial database where as temporal mining is the extraction of knowledge about occurence of an event or values whether they follow cylic,random,seasonal variation etc...and other intrestion time related patterns.
How do you convert spatial code into temporal code?
It can be converted using a Shift register. A Serial-In-Parallel-Out(SISO) shift register is used to convert temporal code to spatial code. A Parallel-In-Serial-Out(PISO) shift register is used to convert spatial code to temporal code.

What is the opposite of history?
from a temporal standpoint: the future from a spatial standpoint: eternity from a spatio-temporal (philosophical) standpoint: possibility
What are the three types of relationships that prepositions reveal?
temporal, spatial, and movement
What is Ecological Displacement?
it is spatial or temporal characteristics of organisms that have changed because of competition.
What are what graphic relations rhythmics spatial relations and temporal relations related to?
Editing
What are what graphic relations rhythmic relations spatial relations and temporal relations related to?
Editing
Differentiate spatial locality vs temporal locality?
Temporal locality that is referenced at one point in time will be referenced again sometime in the near future Spatial locality that likelihood of referencing a resource is higher if a resource near it was just referenced
Identify a correctly processed image?
Magnetic resonance imaging (MRI) has emerged as a powerful tool in medical diagnosis and research. Although high spatial resolution images are essential in medical diagnosis and image analysis, high temporal resolution is equally important in applications of dynamic contrast-enhanced MRI or functional brain MRI. In particular, in breast MRI the ability to differentiate between benign and malignant lesions depends, in part, on the temporal resolution of the dynamic image acquisition. New applications of MRI such as multi-feature analysis of image time series data and full 3D functional MRI or event-related functional MRI require high spatial and high temporal resolution for accurate image analysis on a voxel-by-voxel basis. Currently available partial Fourier reconstruction techniques, which effectively improve the time resolution, suffer from a reduced signal to noise ratio in the reconstructed image, a decrease in spatial resolution or reconstruction artefacts, making numerical image analysis difficult. In this work we present an image reconstruction algorithm based on image recovery theory which effectively doubles the temporal resolution and results in an image quality sufficient for further numerical analysis. The developed algorithm requires a full Fourier space acquisition of a pre-contrast or baseline image prior to the reconstruction procedure of the time series partial Fourier data.

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.
