Abstract
The human activity related with a particular piece of land comes under land use. Land cover is associated to the type of feature present on the earth surface. The regions covered by forests, wetlands, impervious surfaces, agriculture, water types etc comes under land cover.by analyzing satellite and aerial imagery we can determine land cover whereas land use cannot be determined from satellite imagery. Land cover information is used by the managers for better understanding of the present landscapes. There are two methods for collecting information on land covers. They are field survey and remotely sensed imagery analysis. Land change models can be built from these data to assess future shifts in land cover
Keywords: Remote sensing; Cameras; Satellites
Some specific uses of remotely detected pictures of the world include:
• Large forest fires are often mapped from area, permitting rangers to envision a way larger space than from the bottom.
• Tracking clouds to assist predict the weather or look erupting volcanoes, and facilitate waiting for dirt storms.
• Tracking the expansion of a town and changes in farmland or forests over many years or decades.
• Discovery and mapping of the rugged topography of the ocean bottom (e.g., Brobdingnagian mountain ranges, deep canyons, and therefore the “magnetic striping” on the ocean floor).
Remote sensing makes it potential to gather knowledge of dangerous or inaccessible areas. Remote sensing applications embrace observation deforestation in areas like the Amazon Basin, glacial options in Arctic and Antarctic regions, and depth sounding of coastal and ocean depths. Military assortment throughout the conflict created use of stand-off assortment of information regarding dangerous border areas. Remote sensing additionally replaces expensive and slow knowledge assortment on the bottom, guaranteeing within the method that areas or objects don't seem to be disturbed.
Orbital platforms collect and transmit knowledge from completely different elements of the spectrum, that in conjunction with larger scale aerial or ground-based sensing and analysis, provides researchers with enough data to watch trends like El Niño and alternative natural long- and short phenomena alternative uses embrace completely different areas of the world sciences like resource management, agricultural fields like land usage and conservation, Oil spill detection and observation, and national security and overhead, ground-based and stand-off assortment on border areas
Applications of Remote Sensing
Conventional radiolocation is usually related to aerial control, early warning, and sure large-scale earth science knowledge. physicist radiolocation is employed by native law enforcements' observation of speed limits and in increased earth science assortment like wind speed and direction among weather systems additionally to precipitation location and intensity. alternative kinds of active assortment embrace plasmas within the part. Interferometric artificial aperture radiolocation is employed to supply precise digital elevation models of large-scale parcel
• Laser and radiolocation altimeters on satellites have provided a large vary of information. By mensuration the bulges of water caused by gravity, they map options on the seafloor to a resolution of a mile about. By mensuration the peak and wavelength of ocean waves, the altimeters live wind speeds and direction, and surface ocean currents and directions.
• Ultrasound (acoustic) and radiolocation tide gauges live water level, tides and wave direction in coastal and offshore tide gauges.
• Light detection and locomote (LIDAR) are standard in samples of weapon locomote, optical maser well-lighted orienting of projectiles. measuring device is employed to observe and live the concentration of assorted chemicals within the atmosphere, whereas mobile measuring device are often wont to live heights of objects and options on the bottom additional accurately than with radiolocation technology. Vegetation remote sensing could be a principal application of measuring device.
• Radiometers and photometers are the foremost common instrument in use, aggregation mirrored and emitted radiation during a wide selection of frequencies. The foremost common are visible and infrared sensors, followed by microwave, electromagnetic wave and infrequently, ultraviolet. They will even be wont to observe the emission spectra of assorted chemicals, providing knowledge on chemical concentrations within the atmosphere.
• Radiometers also are used at the hours of darkness, as a result of artificial light-weight emissions ar a musical notation of act. Applications embrace remote sensing of population, GDP, and harm to infrastructure from war or disasters.
