Tropical Ecosystem Environment Observation by Satellites (TREES), starting 1991, from JRC

Summary
The monitoring of substantial changes in the forests of the tropical
belt of the Earth presents a formidable yet vital challenge for the
remote sensing community. In order to address this issue a project was
initiated in 1991 by the Space Applications Institute (SAI)
(now the Institute for Environment and Sustainability) within the
Joint Research Center ... (JRC) of the European Commission in
Ispra/Italy. This project, entitled TREES (Tropical Ecosystem
Environment observation by Satellite), is oriented towards the study
of tropical forest dynamics at regional to global scales using remote
sensing techniques. TREES is a joint project of the Commission of the
European Union and the European Space Agency concerned with the
development of space observation techniques for improved mapping and
monitoring of the tropical forests of the world.
Data derived from various satellites, such as the NOAA AVHRR low
spatial resolution instrument, ESA ERS-1 / -2 Synthetic Aperture Radar
(SAR) instrument, as well as Landsat-TM and SPOT are considered. The
optical and thermal channel imagery of the AVHRR instruments are used
for regional scale mapping and condition determination of tropical
forest (over South East Asia, Indonesia, Central and West Africa and
South and Central America). Higher spatial resolution optical imagery
is used to verify the patterns observed, and the classifications
derived from the AVHRR imagery. Tools for processing the ERS SAR data
have been developed and are tested on various sites. A Mosiac of SAR
Imagery from the ERS satellites is being prepared for the entire
Congo Basin. In addition a coherent geographical information system -
Tropical Forest Information System (TFIS) - has been developed to meet
the project's needs for data evaluation and coordination of data
processing.
The project is split into two phases:
- TREES-1 phase comprises data collection, data evaluation, tool
development, definition of intermediate / final products and
presentation of results. This phase was successfully concluded in
December 1994,
- TREES-2 phase comprises continuation of data collection and
initiation of a Monitoring Phase. Presently the project has just
entered phase II.
The JRC has invested considerable time and resources for the
collection of appropriate data (e.g. cloudefree data from optical
sensors) from various sites . The following table describes the AVHRR
data acquisitions to date (June 1995) and will be subject to change in
the future:
Platform / Sensor-------South East Asia------Africa---------South America
NOAA/AVHRR (90-94)----------320---------------250---------------130----
The TREES Phase 1 products are to be released on CD-ROM. The beta
version is in test and final versions will be released in September
1995. Contact Dr. Frederic Achard, TREES, GVM Unit, JRC 21020 Ispra.
