TL;DR: It is shown that there was a gross loss of tropical forests in the 1990s and 2000s and that carbon loss rates did not change between the two last decades, reconciling recent low estimates of carbon emissions from tropical deforestation.

Change in tropical forest cover of Southeast Asia from 1990 to 2010
TL;DR: In this paper, a systematic sample of 418 sites (10 km × 10 km size) located at the one-degree geographical confluence points and covered with satellite imagery of 30 m resolution is used for the assessment.
Pre-processing of a sample of multi-scene and multi-date Landsat imagery used to monitor forest cover changes over the tropics

TL;DR: In this article, the TREES-3 project has processed more than 12,000 Landsat TM and ETM+ data subsets systematically distributed over the tropics, and the results show that the haze correction algorithm has improved the visual appearance of the image and significantly corrected the digital numbers for the red band.

An automated approach for segmenting and classifying a large sample of multi-date Landsat imagery for pan-tropical forest monitoring
Rastislav Raši,Catherine Bodart,Hans-Jürgen Stibig,Hugh Eva,René Beuchle,Silvia Carboni,Dario Simonetti,Frédéric Achard +7 more
TL;DR: The component of visual refinement of the mapping results had a notable impact on forest area and change estimates: for a set of sample sites in Southeast Asia the rate of change in tree cover (deforestation) was assessed at 0.9% and 1.6% before and after visual control, respectively.

Automatic Updating of an Object-Based Tropical Forest Cover Classification and Change Assessment
TL;DR: The method developed for the automatic change detection and classification of year 2010 imagery integrating the existing segmentation and classification results of the period 1990–2000 is presented.
