Types of aerial photographs and Aerial film camera

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. Some examples are The period from 1960 to 2010 has experienced some major changes in the field of remote sensing. The background for many of these changes occurred in the 1960s and 1970s. Some of these changes are outlined below. First, the term remote sensing was initially introduced in 1960. Before 1960 the term used was generally aerial photography In general, remote sensing can be divided into two types: Aerial Remote Sensing and Satellite Remote Sensing. Aerial Remote Sensing . Aerial remote sensing was carried out at first with balloons in 1858. With the discovery of aeroplanes in 1902, remote sensing was carried out through photographing from airplanes, right from 1909 Aerial photographs are captured most commonly as panchromatic (black and white), color, or false-color infrared; however, various types of electromagnetic radiation can also be recorded onto photographic film with the use of different emulsions and filters (Cohen et al. 1996)

Other types of remote sensing include stereographic pairs created from multiple air photos (often used to view features in 3-D and/or make topographic maps), radiometers and photometers that collect emitted radiation from infra-red photos, and air photo data obtained by satellites such as those found in the Landsat program Analog aerial photography, videography, and digital photography are commonly used in airborne remote sensing.Synthetic Aperture Radar imaging is also carried out on airborne platforms. Analog photography is capable of providing high spatial resolution Remote Sensing is a technology to gather information and analyzing an object or phenomenon without making any physical contact. This technology is used in numerous fields like geography, hydrology, ecology, oceanography, glaciology, geology. A geographic information system is a tool that is used for mapping and analyzing feature events on Earth

Remote sensing is the science and art of identifying, observing, and measuring an object without coming into direct contact with it. This involves the detection and measurement of radiation of different wavelengths reflected or emitted from distant objects or materials, by which they may be identified and categorized Remote Sensing Platforms. Using the broadest definition of remote sensing, there are innumerable types of platforms upon which to deploy an instrument. Discussion in this course will be limited to the commercial platforms and sensors most commonly used in mapping and GIS applications. Satellites and aircraft collect the majority of base map. Remote Sensing & GIS Applications. Remote sensing and GIS techniques can be used for generating development plans for the watershed area in consonance with the production potential and limitation of terrain resources, and can also be used for assessing the impact of these measures before actual implementation in the field. Language: English Remote sensing data are being used for mapping potential glacier lake outburst floods (GLOF) in the Himalayas. The most frequent applied areas of remote sensing in India is the study of Earth's subsurface and surface features. Aerial photographs are an effective tool for geological, geomorphological, relief and hydrological studies and land.

What is remote sensing and what is it used for

Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other flying object. Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs or drones), balloons, blimps and dirigibles, rockets, pigeons, kites, parachutes, stand-alone telescoping and vehicle-mounted poles.. Mounted cameras may be triggered remotely. Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about the Earth and other planets. Remote sensing is used in numerous fields, including geography, land surveying and most Earth science disciplines (for example. ADVERTISEMENTS: The following points highlight the top fifty applications of remote sensing. Some of the applications are: 1. Measuring gravity with the GRACE satellites 2. Deriving elevation and contours using photogrammetry 3. Watching the aurora borealis from another angle 4. Comparing the past and present with human impact change 5. Planning an optimal telecom network [ The technology of modern remote sensing has a very long history, dating back to the end of the 19th century with the invention of the camera. Initially cameras were used to take photographs on the ground, which provided (and still does) a fascinating and exciting way to capture moments in time and keep a record of something that happened, which looked more realistic than a drawing or painting. Based on this definition, many techniques such as satellite remote sensing, aerial photography, geophysical surveys, ground spectroscopy or even terrestrial laser scanners, are considered as remote sensing techniques (Johnson, 2006). Remote sensing has opened up new horizons and possibilities for archaeology
