ICESat/GLAS Data as a Measurement Tool for Peatland Topography and Peat Swamp Forest Biomass in Kalimantan, Indonesia [PDF]

open access: yes, 2011
Indonesian peatlands are one of the largest near-surface pools of terrestrial organic carbon. Persistent logging, drainage and recurrent fires lead to huge emission of carbon each year.

Free global DSM assessment on large scale areas exploiting the potentialities of the innovative google earth engine platform [PDF]

open access: yes, 2017
The high-performance cloud-computing platform Google Earth Engine has been developed for global-scale analysis based on the Earth observation data. In particular, in this work, the geometric accuracy of the two most used nearly-global free DSMs (SRTM and

Contribution of leaf specular reflection to canopy reflectance under black soil case using stochastic radiative transfer model [PDF]

open access: yes, 2018
Numerous canopy radiative transfer models have been proposed based on the assumption of “ideal bi-Lambertian leaves” with the aim of simplifying the interactions between photons and vegetation canopies.

The impact of digital elevation models resolution on tectonic activity assessment based on morphotectonic indices: a case study of Seulawah Agam Volcano, Indonesia

open access: yesJournal of Degraded and Mining Lands Management, 2023
The Digital Elevation Number (DEM) is the main tool for quantitative geomorphological tests. Furthermore, Shuttle Radar Topography Mission (SRTM) images with a resolution of 30 m have been widely used as a source of DEM data in geomorphological studies ...

Abiotic controls on macroscale variations of humid tropical forest height [PDF]

open access: yes, 2016
Spatial variation of tropical forest tree height is a key indicator of ecological processes associated with forest growth and carbon dynamics. Here we examine the macroscale variations of tree height of humid tropical forests across three continents and ...

Were rivers flowing across the Sahara during the last interglacial? Implications for human migration through Africa. [PDF]

open access: yes, 2013
Human migration north through Africa is contentious. This paper uses a novel palaeohydrological and hydraulic modelling approach to test the hypothesis that under wetter climates c.100,000 years ago major river systems ran north across the Sahara to the ...
