The world around us is changing constantly. Technologies develop, progress takes its place. However, one thing stays permanent: humans still depend on environment. And partially well-being of people is related to plants. Plants allow people to breathe, plants give us food, shelter, medicaments and many other crucial things. Yet, uncontrolled agriculture, transition to monoculture farming within entire countries, climate change – all these factors have negative effect on vegetation layer. Moreover, human population grows exponentially, and the issue of food supply arises more sharply.
That’s why nowadays there is a steady tendency to preserve what we possess at the moment. And here satellite monitoring over vegetation condition comes to help. Also satellite monitoring facilitates work of farmers and lets decrease costs and losses in case of negative weather phenomena such as floods and drought. Whenever it is an emergency situation or farming planning there is a great helping tool that is satellite imagery which provides a vegetation index (NDVI) and a water index (NDWI).
