ABSTRACT.
After the first program, with title “Use of LANDSAT
data for natural resources investigation in the lower Basin
of Danube and Danube Delta” having as principal
investigator prof. N. Oprescu, which was included by
NASA in 1972 between their over 300 characteristic sites
of the whole Earth, carried out in 1977, the researches in
this field were much more diversified and deeply treated
under the tutorial of the former CRAS (Romanian
Comission for Spatial Activities), and "Intercosmos"
organisation until 1989 and now under the tutorial of
remote sensing program of the Romanian Space Agency.
With collaboration with some remote sensing
laboratories, the problems covering by this program are:
* The natural inventory and monitoring the evolution
for:
natural and cultivated vegetation;
monitoring of water resources;
geomorphological state;
The evolution of the coastal zone and the continental
platform of the Black Sea;
* Monitoring of the pollution.
The used methods and procedures are presented. Thus,
analogical processing, digital processing (as density
slicing, edge detection, image enhancement, colour
composite in different modes, etc), and mixed procedures
applied on aero-satellite recordings are presented,
together with the results for Danube Delta and continental
platform of the Black Sea. A qualitative and quantitative
evaluation of them is also presented.
Finally, some proposals are made for participation to
the big european projects for Danube Delta and Black
Sea also for a partnership in the frame of the
Rmanian — Hungarian program “OPEN SKYIES”
and also with Hungaria, Czechia and Slovakia in the
project “TOTAL SOLAR ECLIPSE - 99”.
The paper is riched illustrated, including numerous
slides.
1. INTRODUCTION - BACKGROUND -
AIMS.
- In Romania, as well as in the Central —
Eastern European countries crossing this period
of transition, privatisation and reforms, we can
see some characteristics focused, in this case,
on specific remote sensing;
- The remote sensing problem applied in
various branches of national economy is facing
the major dificulty: the lack of satellite
recordings, or the lack of money to provide
them. We have to use at a maximum level the
few satellite recordings we have, which we
have got from international cooperations, so we
cannot conceive and run programs that need
some types of recordings, from adequate and
precise date:
- Practically, satellite recordings we receive
in programs and projects of international
cooperation, are “historic” by the time they
come to us so can’t be used for fast and
medium time variable objects and phenomena:
- The lack of specific and clear rules for
satellite ^ recordings circulation — between
