- A significant result is the use of hystorical 
LANDSAT data and of ERS recording type and 
also to use the procedure of intrinsec 
dimensionality to reduce, for some applications 
the number of the needed recordings, using 
radiometric determinations on the characteristic 
profiles which are to be made seasonaly. 
- Using the procedure of “confusion matrix” 
(combined qalitative and quantitative criteria) 
an accuracy of classification of about 92% are 
obtained. 
3, COOPERATION PROPOSALS, 
FURTHER DEVELOPMENTS. 
- participation to the big european projects for 
Danube Delta and Black Sea; 
- partnership in the frame of the Romanian — 
Hungarian program “OPEN SKYIES” and also 
with Hungaria, Czechia and Slovakia in the 
project “TOTAL SOLAR ECLIPSE — 99”; 
- to conceive, to launch and implement 
adeqate Pilot Project, in the frame of the 
programs ESA — Envisat and also in Radarsat. 
- For each proposals are ellaborated the 
necessary documantation.
