What is remote sensing platforms?
Platforms refer to the structures or vehicles on which remote sensing instruments are mounted. These attributes include: distance the sensor is from the object of interest, periodicity of image acquisition, timing of image acquisition, and location and extent of coverage.
What are the difference between remote sensing satellites and platforms?
In space- borne remote sensing, sensors are mounted on-board a spacecraft (space shuttle or satellite) orbiting the earth. Space-borne or satellite platform are onetime cost effected but relatively lower cost per unit area of coverage, can acquire imagery of entire earth without taking permission.
What is ground based platforms in remote sensing?
Ground-based platforms include hand held cameras (film or digital), cranes, ground vehicles, tethered balloons, and even towers. Ground-based platforms typically provide up to 50 meters elevated remote sensing data and are useful for acquiring low altitude imagery with frequent coverage for dynamic phenomena.
What is the difference between sensor and platform?
Sensor is an instrument, mounted on a stable platform away from the Earth, which collects and records energy reflected or emitted from the target. The platforms orbit in space in different orbits either near or away from the Earth.
What is remote sensing and types of remote sensing?
There are two types of remote sensing technology, active and passive remote sensing. Active sensors emit energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation that is reflected or backscattered from the target.
What are the types of remote sensing?
Remote sensing instruments are of two primary types:
- Active sensors, provide their own source of energy to illuminate the objects they observe.
- Passive sensors, on the other hand, detect natural energy (radiation) that is emitted or reflected by the object or scene being observed.
What are the advantages and disadvantages of various remote sensing platforms?
What Are the Advantages and Disadvantages of Remote Sensing?
- Remote Sensing Technology Can Survey Large and Inaccessible Areas.
- Remote Sensing Data Can Have a Wide Range of Uses.
- Point Cloud Software Analyzes Data Quickly.
- Remote Sensing Doesn’t Disturb People or the Environment.
What is meant by platform?
A platform is a group of technologies that are used as a base upon which other applications, processes or technologies are developed. In personal computing, a platform is the basic hardware (computer) and software (operating system) on which software applications can be run.
What are the 5 types of remote sensing?
Types of Remote Sensing Systems
- Visual Remote Sensing System such as human visual system.
- Optical Remote Sensing.
- Infrared Remote Sensing.
- Microwave Remote Sensing.
- Radar Remote Sensing.
- Satellite Remote Sensing.
- Airborne Remote Sensing.
- Acoustic and near-acoustic remote sensing.
Is GPS a remote sensing?
Remote sensing is a GIS data collection and processing technique. GPS (global positioning system) is a way to assign a location to a point on the Earth. Remote sensing is the use of sensors on board either planes or satellites to collect data usually in a grid like pattern of pixels called raster data.
