Drones to Study Natural Resources and Vegetation
Satellites help us in several ways to study natural resources, vegetation patterns and agricultural crop production trends. Satellite imagery has to be supplemented with close-range sharp and detailed images derived from airborne campaigns and/or drones. Researchers have concentrated on accumulating data about forest plantations, their fluctuations and the extent of loss of forests in a given area, using satellite imagery. Satellite-mediated observation of sandy terrain and cropping belts too are conducted regularly. A comparative analysis of drones, airborne campaigns and satellites and their utility in analysing natural resources is useful. Drones could also have a strong impact on assessing weather related changes on water resources and on crop productivity. Drones actually offer cost effective monitoring of forest gaps, tree health and productivity. A digital library or data bank of various forest tree species traced in the region, along with their spectral signatures, is a useful idea. Traditional methods of tree planting, particularly, planting sets/explants or seed dibbling is slow process.
