Remote Sensing Pdf Electromagnetic Spectrum Remote Sensing In general, the resolution is the minimum distance between two objects that can be distinguished in the image. objects closer than the resolution appear as a single object in the image. What is remote sensing? collecting information about an object without being in direct physical contact with it.
Remote Sensing Pdf Remote Sensing Earth Sciences The size of the pixel is related to the resolution of the total picture. the larger the pixel size the lower the resolution and the smaller the pixel size the higher the resolution. nasa has to address these same types of questions as they design remote sensing satellites. Spatial resolution refers to the size of the smallest feature that can be detected by a satellite sensor or displayed in a satellite image. it is usually presented as a single value representing the length of one side of a square. Remote sensing is the process of obtaining information about an object using a sensor which is physically separated from the object. remote sensing rely on sensors, which detect emitted or reflected energy from objects. human vision is the most popular example of a remote sensing system. In fine or high resolution images, small objects can be detected. military sensors for example, are designed to view as much detail as possible, and therefore have very fine resolution.

Spectral resolution describes the ability of a sensor to define fine wavelength intervals. the finer the spectral resolution, the narrower the wavelength range for a particular channel or band. These details are broadly referred to as resolution, which can be described in terms of time, space, spectral and radiometry. resolution of a sensor system is its capability to discriminate two closely spaced objects from each other. in this unit, you will study about the resolution and its types. Remote sensing system capture radiation in different wavelength reflected emitted by the earth’s surface features and recorded it either directly on the film as in case of aerial photography or in digital medium used for generating the images. Spatial resolution of images acquired by satellite sensor systems is usually expressed in meters. for example, we often speak of landsat as having “30 meter" resolution, which means that two objects, thirty meters long or wide, sitting side by side, can be separated (resolved) on a landsat image.
