Characteristics of Remote Sensing Remote sensing is characterised by; Sensor Stage (satellite, plane, kite, ground based) View (angle of view Remote Sensing. Spectral Signatures. A primary use of remote sensing data is in classifying the myriad features in a scene (usually presented as an image) into meaningful categories or classes. The image then becomes a thematic map (the theme is selectable e.g., land use, geology, vegetation types, rainfall)

Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers sense things about the Earth • The radiometric characteristics describe the actual information content in an image • Every time an image is acquired on film or by a sensor, its sensitivity Pre-processing of remote sensing image • Each of these will vary depending on the specific sensor and platform used to acquire the data and the conditions during dat Although ground-based and aircraft platforms may be used, satellites provide a great deal of the remote sensing imagery commonly used today. Satellites have several unique characteristics which make them particularly useful for remote sensing of the Earth's surface.

Unsupervised classification is where the outcomes (groupings of pixels with common characteristics) are based on the software analysis of an image without the user providing sample classes Remote sensing image denoising faces many challenges since a remote sensing image usually covers a wide area and thus contains complex contents. Using the patch-based statistical characteristics is a flexible method to improve the denoising performance.
