What are the application of remote sensing in forestry?
There are many forestry applications that remote sensing can be used for. Some of these applications include terrain analysis, forest management, recultivation, updating of existing forest inventories, forest cover type discrimination, the delineation of burned areas, and mapping of cleared areas.
What is the difference between remote sensing and GIS?
A geographic information system (GIS) is a computer-based tool for mapping and analyzing feature events on earth. Remote sensing is the art and science of making measurements of the earth using sensors on airplanes or satellites.
What is the importance of remote sensing?
The advantages of remote sensing include the ability to collect information over large spatial areas; to characterize natural features or physical objects on the ground; to observe surface areas and objects on a systematic basis and monitor their changes over time; and the ability to integrate this data with other …
What are 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 advantage and disadvantages of remote sensing?
Remote Sensing
| Advantages of remote sensing | Limitations of remote sensing |
|---|---|
| Relatively cheap compared to employing a team of surveyors | Objects can be misclassified or confused |
| Easy & quick collection of data. | Distortions may occur in an image due to the relative motion of sensor & source. |
What are disadvantages of remote sensing?
Remote Sensing Instruments – Disadvantages:
- Expensive to build and operate!!!!
- Measurement uncertainty can be large.
- resolution is often coarse. 88D pulse volume is over 1.5 km wide at 100 km range from radar.
- Data interpretation can be difficult.
