More Details continutly …………
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)
Photos from Agriculture applications
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
