1- Water resources ► ► Census of phytoplankton biomass in marine regions, lakes and rivers ► ► Estimation of chlorophyll, suspended solids (organic and inorganic), of the diluted organic material (CDOM), of Poseidonia and of the aquatic vegetation in coastal regions, lakes and rivers ► ► Mapping and monitoring of the coastlines and the coastal bottom of the sea ► ► Mapping of the wetlands ► ► Measurement of the optical properties of the water and its opacity. ► ► Investigation of the natural and biological processes that affect the fish farming ► ► Detection of coastal and submarine sources of water. ► ► Mapping and monitoring of snow covered regions. Estimation of equivalent quantity of water.

2-Agriculture ► ► Explanation and mapping of types of cultures ► ► Detection and follow-up of the effects of farming of natural chemical and anthropogenic factors like salinity of soil, nitrates, organic materials, nutrients deficiency, dryness, pollution of soil, weeds, etc. ► ► Evaluation of the agricultural production ► ► Evaluation of the quality of soil (content of organic material) and monitoring its corrosion ► ► Measurement of natural and biological parameters of the farming such as Leaf Area Index (LAI), humidity content etc.. ► ► Investigation, census and monitoring of the health of faming ► ► Planning of farming (precision farming)

3-Field Environment ► ► Mapping and monitoring of the changes of uses/ covers of land ► ► Census of environmental burdens by natural disasters ► ► Census of the effects caused by human actions (industrial pollutants, dust exhaust fumes) and natural parameters (dryness, increase of humidity, etc.) in the environment ► ► Mapping of mine acid waste (copper, etc) ► ► Restoration of quarries and mines ► ► Detection and monitoring of blighted areas due to pollution ► ► Monitoring of the environmental changes in active and abandoned industrial areas ► ► Locating a place for a landfill of waste, factories, plants etc. ► ► Detection of ground saturated with diesel which comes from underground conductors and refineries leakages

4-Forestry ► ► Mapping of forests and their characteristics like phytomass density, structure, etc. ► ► Monitoring of the natural state of forests ► ► Planning and monitoring of reforestation

5-Geology /Edaphology ► ► Detection of available extractives ► ► Mapping of surface appearances of minerals ► ► Lithology Mapping ► ► Stratigraphic Mapping ► ► Geo-botanical Mapping ► ► Analysis of geological structures

6-Detection of oil sources Use of four indexes based on hyperspectral data indicative for detection of possible sources of oil: ► ► A- Detection of transformed ores, ► ► B- Detection of geo-botanical abnormalities (farming illness due to large collection of hydrocarbons) ► ► C- Detection of asphalt minerals in the soil, and ► ► D- Detection of soils contaminated by oil leaks
