Climate change mitigation mechanisms, such as REDD+, which aim at avoiding deforestation and forest degradation, require an accurate aboveground biomass (AGB) monitoring. In the present study, multi-temporal X-(TerraSAR-X) and L-band (ALOS PALSAR) SAR data and a multispectral RapidEye image were analyzed for their ability to estimate AGB in a tropical forested peatland area in Central Kalimantan o...Show More
We estimated forest Above Ground Biomass (AGB) of tropical peat swamp forests in the Indonesian province of Central Kalimantan through correlating airborne Light Detection And Ranging (LiDAR) data to forest inventory data. Two LiDAR point cloud metrics, the Quadratic Mean Canopy profile Height (QMCH) and the Centroid Height (CH), were correlated to the field derived AGB estimates. The regression m...Show More
Climate change mitigation schemes, such as REDD and biodiversity conservation in tropical rainforests, necessitate remote sensing based forest monitoring capabilities with high spatial resolution and temporal coverage. Regular monitoring has to be capable of detecting rapid changes in forest extent, i.e. deforestation, and subtle changes to the forest cover caused by logging and/or fire, described...Show More
In the context of climate change mitigation mechanisms for avoiding deforestation, i.e., reducing emissions from deforestation and forest degradation (REDD+), comprehensive forest monitoring, especially in tropical regions, is of high relevance. A precise determination of forest carbon stocks or aboveground biomass (AGB) for large areas is of special importance.Show More
The objective of this letter was to investigate the performance of the C-band Advanced Synthetic Aperture Radar (ASAR) instrument onboard the European ENVISAT satellite for mapping fire scars in boreal forest ecosystems. The Wide Swath Mode (WSM) of the cloud and haze-penetrating ASAR instrument with a spatial resolution of 150 m would be ideal to support nearly real-time fire monitoring and impac...Show More
The Sebuku-Sembakung area of north-eastern Kalimantan, Indonesia (Borneo) has been proposed by the WWF as a national park because of its large biodiversity with habitats including various types of tropical forests and swamps. Currently, only low resolution DEM data exists for the area. This has motivated an effort to produce a topographic map of the region using L-band repeat pass interferometry w...Show More
In 1997/98 Indonesia has experienced one of the greatest fire disasters ever observed in a tropical rainforest environment in SE-Asia. Following this event ESA and NASDA decided to set up a cooperation project to compare and combine the capabilities of the two SAR satellite sensors systems ERS-1/2 and JERS-1 aiming at an in depth analysis of this disaster. It was investigated whether these SAR sys...Show More
Presents results gathered from the project "Tropical Rainforest and Use of Land Investigation" project-TRULI, which was sponsored by the German Space Agency (DARA), ESA/ESRIN and ADRO deploying data from the European ERS-1R, the Canadian RADARSAT and JERS between 1993 and 1998. The focus is on the possibilities of monitoring deforestation in the wet tropics from space by means of visual interpreta...Show More
In spring 1998 fires have devastated large areas of tropical rainforests in Kalimantan Timur on the island of Borneo in Indonesia. The authors report on results of the synergistic use of NOAA-AVHRR and multitemporal ERS-2 SAR data to analyze this disaster. Using a temporal sequence of more than 150 NOAA-AVHRR hotspot data sets acquired from January to April 1998 and a multitemporal series of 6 ERS...Show More
