چکیده

The mosaics are generated from the original 20 m resolution L-band SAR data, acquired in HH and HV polarisations. While ALOS PALSAR features a full-polarisation option, the dual-polarisation mode was selected as trade-off between mission programmatic restrictions and thematic information. To facilitate more rapid processing and file handling, the data are processed as extended strip images, 70 km in width and up to some 3000 km long, and filtered to 50 m pixels spacing to reduce speckle and data amounts.

Generation of Decadal Global High Resolution L-band Sar Dataset for Forest Carbon Tracking

Recently, the forest observation using the spaceborne sensor becomes a top issue in the carbon monitoring. Covering more than 20% of the global terrestrial areas, forests are rapidly decreasing, corresponding to 20% carbon dioxide release from the land. Deforestation and forest degradation mainly occurred in the developing country. L-band SAR is sensitive for monitoring the forest biomass, fore...

A 50-m Forest Cover Map in Southeast Asia from ALOS/PALSAR and Its Application on Forest Fragmentation Assessment

Southeast Asia experienced higher rates of deforestation than other continents in the 1990s and still was a hotspot of forest change in the 2000s. Biodiversity conservation planning and accurate estimation of forest carbon fluxes and pools need more accurate information about forest area, spatial distribution and fragmentation. However, the recent forest maps of Southeast Asia were generated fr...
