Annual Maps of Forests in Australia from Analyses of Microwave and Optical Images with FAO Forest Definition

Journal of Remote Sensing, 2021
The Australian governmental agencies reported a total of 149 million ha forest in the Food and Agriculture Organization of the United Nations (FAO) in 2010, ranking sixth in the world, which is based on a forest definition with tree height>2 meters. Here,

Palsar i Vissátvuopmi: Kartering och klassificering utifrån DEM-raster [PDF]

, 2020
Palsar är torvkullar med en kärna av permafrost som förekommer i subarktiska miljöer med diskontinuerlig permafrost. Palsarna är mycket känsliga för klimatförändringar och har minskat snabbt till följd av den globala uppvärmningen, med bland annat ...

Monitoring of an Indonesian Tropical Wetland by Machine Learning-Based Data Fusion of Passive and Active Microwave Sensors

Remote Sensing, 2018
In this study, a novel data fusion approach was used to monitor the water-body extent in a tropical wetland (Lake Sentarum, Indonesia). Monitoring is required in the region to support the conservation of water resources and biodiversity.

Topographic Correction for ALOS PALSAR Interferometry [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2010
L-band synthetic aperture radar (SAR) interferometry is very successful for mapping ground deformation in densely vegetated regions. However, due to its larger wavelength, the capacity to detect slow deformation over a short period of time is limited.

Identification of Mangrove Changes in the Mahakam Delta in 2007-2017 Using Alos/Palsar and Landsat

, 2022
The mangrove area in the Mahakam Delta has dynamically changed due to the land-use conversion for various purposes. Various remote sensing data can monitor the changes, for example, ALOS/PALSAR and Landsat imagery. However, there are limited studies that

PALSAR SCANSAR SCANSAR Interferometry

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
We have examined the capability of the PALSAR SCANSAR SCANSAR interferometry by observing the African forest and Sahara desert, both of which are separated 46 days in March and April of 2008. These two paths are well tuned for the orbital tube of 200 m and the beam synchronization of the transmission positions in 200 m to 500 m, we have succeeded the ...
