Classification
system:
|
Differentiation
of 6 classes (water, cloud, cloud shadow, forest, secondary growth
forest, and non-forest)
|
|
Remote
sensing data:
|
Landsat
MSS/TM (mid 1970s, mid 1980s, and early 1990s; acquired in
Amazon, Central Africa, and Southeast Asia)
|
Interpretation
process:
|
Analysis
follows a hybrid methodology based on digital image processing and
visual
interpretation of color
photoproducts
Classification is based on a series of thresholds used to
isolate each class. In
general, visible bands are used to discriminate between forest
and non-forest,
whereas, the near infrared bands are used to separate forest
from early secondary
growth forests |

Objective:
|
Mapping coverage of the closed tropical forests, generating a 3-epoch
forest/non-forest
data set showing areas of deforestation in the moist tropical
forest regions
Quantification
and mapping of the rate of deforestation in the tropics
Calculation and analysis of the net annual exchange of
carbon between tropical
ecosystems and the atmosphere from deforestation, reforestation,
and degradation
using a large- scale, geographically-referenced carbon model

Costs:
|
Users can
co-purchase Landsat 7 data for one half of
the original price. TRFIC shares the cost in order to assist in moving
high resolution, current satellite data to the user community. In
co-purchasing these data with TRFIC, users join the data cooperative
and receive scene credits |
