What are the three remote sensing platforms?
What are the three remote sensing platforms?
There are three broad categories of remote sensing platforms: ground based, airborne, and satellite.
What are platforms in remote sensing?
Platform is a stage where sensor or camera is mounted to acquire information about a target under investigation. According to Lillesand and Kiefer (2000), a platform is a vehicle, from which a sensor can be operated. For remote sensing applications, sensors should be mounted on suitable Page 3 stable platforms.
How many types of satellite platforms are there?
There are two types of well recognized satellite platforms- manned satellite platform and unmanned satellite platform.
What is called the platform of satellite remote sensing?
Satellites provide the spaceborne platform for sensors and are indeed the most common remote sensing platform. The path followed by a satellite is referred to as its orbit. Compared with manned spacecraft satellites offer many advantages.
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 is the difference between a platform and a sensor?
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 are spaceborne platforms?
Spaceborne platforms include the space station as well as both low-level (700 to 1500 km) and high-level (~ 36,000 km) satellites. These types of platforms can acquire large areas of data in a short amount of time, which can be used to monitor Earth resources, atmospheric dynamics, and other applications.
Why is remote sensing expensive?
Remote sensing is a fairly expensive method of analysis especially when measuring or analyzing smaller areas. Powerful active remote sensing systems such as radars that emit their own electromagnetic radiation can be intrusive and affect the phenomenon being investigated.
What are the four types of remote sensing?
Types of Remote Sensing. The most common types of remote sensing used in agriculture can be divided into four main categories of resolution, including spatial resolution, spectral resolution, radiometric resolution, and temporal resolution.
What is a good example of remote sensing?
Weather maps and satellite imaging is a good example of remote sensing.
What do we use remote sensing satellites for?

What to major for remote sensing?
Astronomy offer a major in Remote Sensing for the Bachelor of Science degree program. Remote Sensing students will study Geography, Environmental Science and Physics, as well as other topics focused on field studies. Students will learn to record and interpret images using highly specialized instruments, some of which are unique to the Remote Sensing program at the U of L.
