What are the applications of remote sensing in forestry?
As a result, remote sensing has been used in a diverse range of forest ecology and management applications from mapping invasive species to monitoring land-cover changes, such as habitat fragmentation, to estimating biophysical and biochemical properties of forests.
What are the applications in remote sensing?
The applications of remote sensing include land-use mapping, weather forecasting, environmental study, natural hazards study, and resource exploration.
How is the remote sensing used in monitoring forest cover?
Remote sensing coupled with GIS (Geographical Information System) as a potential tool, for monitoring the changes in land cover at regional as well as global scale in developing countries, mainly by identifying the conservation priorities in global hotspots, rate of deforestation and quantification of overall forest …
How can GIS be used in managing a forest?
We use GIS to visualize and give shape to abstract and complex data sets. GIS enhances forest management by assisting land owners and forest managers to evaluate and analyze the species diversity, age and size of timber, timber density, and volume.
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 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 importance of remote sensing?
What are the principles of remote sensing?
Remote sensing uses a part or several parts of the electromagnetic spectrum. It records the electromagnetic energy reflected or emitted by the earth’s surface. The amount of radiation from an object (called radiance) is influenced by both the properties of the object and the radiation hitting the object (irradiance).
What are the characteristics of remote sensing?
Characteristics of Remote Sensing Sensor Stage (satellite, plane, kite, ground based) View (angle of view) Type of radiation sensed (visible light, infrared, radar) Time of capture.
What is the main application of remote sensing in forest management?
The main application of remote sensing in forest management has been focused on timber harvest planning and monitoring of logging and deforestation.
What is the relationship between remote sensing and GIS?
Remote sensing and GIS are complementary technologies that, when combined, enable improved monitoring, map-ping, and management of forest resources (Franklin 2001). The information that supports forest management is stored primarily in the form of forest inventory databases within a GIS environment. A forest inventory is a survey of the loca-
What is multi-stage approach in remote sensing?
Multi-stage approach is being adopted by the National Remote Sensing Agency (NRSA), which gives information like timber volume. Apart from forestland classification, stock mapping and volume estimation, remote sensing is also used for damage assessment and fire detection, which is a common feature of Indian forests.
What are the satellite aplications for effective forest management?
The satellite aplications for effective forest management on a more scientific basis commensurating with the priorities set at state, District and Micro levels studies.
