Can remote sensing techniques be used to monitor forest fires?
Mapping of burnt areas and assessment of wildfire effects is one of the most successful applications of satellite remote sensing. Satellite remote sensing provides the means for acquiring comprehensive and harmonized information on wildfire effects for large territories at low cost.
How does a GIS help fight forest fires?
GIS allows you to analyze, visualize, and prioritize values at risk, such as housing developments, utility infrastructure, wildlife, and natural or cultural resources. Many communities use GIS to analyze their vulnerability to wildfire.
How are forest fires monitored?
One of the ways of monitoring a fire is through direct observation for things such as flame length. By monitoring smoke in certain affected areas, we can also better determine whether air quality and visibility conditions during fires meet safety and health standards.
How to detect fire using remote sensing?
Forest fire monitoring by remote sensing can be achieved through the use of polar- orbiting and geostationary satellites. The polar orbiting satellites that are used in fire detection and monitoring include MODIS, AVHRR, ASTER and Landsat. The application of these satellites is limited by their temporal resolutions.
Which satellite data is useful in forest fire?
The forest fire detection and monitoring system uses satellite data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra and Aqua satellites, whose data can be used to track changes in landscape over time.
What are the main satellite sensors used to identify possible fires from space?
US National Oceanic and Atmospheric Administration (NOAA) and Moderate Resolution Imaging Spectroradiometer (MODIS) satellites are being used for fire detection worldwide due to their high temporal resolution and ability to detect fires in remote regions.
What are some other possible incident related uses for GIS data?
Common uses of GIS include inventory and management of resources, crime mapping, establishing and monitoring routes, managing networks, monitoring and managing vehicles, managing properties, locating and targeting customers, locating properties that match specific criteria and managing agricultural crop data.
Which sensor is used for forest fire detection?
Detection of forest fires using CO2 sensors When forest fires burn, they emit large volumes of carbon dioxide gas (CO2); you can use a network of IoT CO2 and temperature sensors for forest fire detection.
How is remote sensing used 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.
How is GIS used in forest management in India?
India’s forest areas have been decreasing rapidly, and a system of continuous operational monitoring is necessary. Coloured infrared aerial photography helps assess the annual occurrence of losses, especially in the less accessible areas. Thermal scanners can detect fire.
How are satellites used to monitor forest fires?
Satellite and aircraft surveillance have become an essential part of fire management. A major break through in the use of satellites for monitoring fires came with the 1999 launch of the MODIS instrument on board the Terra satellite.
How is remote sensing being used in India?
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.
