IRS and Bush fire monitoring
India
uses IRS 1C and IRS 1D for forest and agricultural mapping at present.
These satellites could provide information on extent of forest cover,
canopy cover (open and close forests), timber content, and density of
forests. ``Forest fires can be detected,''
``In
mapping forest cover, black and white imagery is not useful. Both for
agriculture and forest data multi-spectral mapping is required,''
Forest
department uses IRS satellite imagery to survey and monitor the state's
forest areas.
A project initiated by the Forest
Department in India to monitor and detect the presence of forest fires
with the help of satellites detected as many as 180 cases, of various
intensities, across the State from January to June this year. It has
been reported that the fires, however, ranged from high to moderate and
low intensities, and did not cause any serious harm. The study has
helped identify the most vulnerable areas in terms of the occurrence of
forest fires.
Using
satellite images, the project, "Standardisation of geospatial
database of forest department," has been able to identify divisions
that are prone to forest fire during summer.
The project, which took about two years to complete, covers 40,000 sq km
of forest area with an open forest area of 10,835 sq km and 26,156
sq km of dense forest. It has used Indian Remote Sensing Satellite 1-C
and 1-D for the spatial mapping.
The spatial images have identified the extent of dry deciduous,
scrub vegetation, evergreen, semi-evergreen forests and
grasslands.
The spatial mapping comprises identification of fire risk zonation
wherein pockets prone to forest fire during summer are indicated
on the maps.
Remote sensing, the fire-risk zonation helps forest authorities
manage pockets that are more prone to fires due to its proximity
to the villages.
