Online Rainfall Atlas of Hawai‘i

TL;DR: The Rainfall Atlas of Hawai'i as discussed by the authors is a set of digitalmaps of the spatial patterns of the 1978-2007 meanmonthly and annual rainfall for the major Hawaiian islands.
Journal ArticleDOI

Isolating individual trees in a savanna woodland using small footprint lidar data

TL;DR: In this paper, a new method of detecting individual treetops from lidar data and applying marker-controlled watershed segmentation into isolating individual trees in savanna woodland is presented.
Journal ArticleDOI

A survey of remote sensing-based aboveground biomass estimation methods in forest ecosystems

TL;DR: A survey of current biomass estimation methods using remote sensing data and discusses four critical issues – collection of field-based biomass reference data, extraction and selection of suitable variables fromRemote sensing data, identification of proper algorithms to develop biomass estimation models, and uncertainty analysis to refine the estimation procedure.
Journal ArticleDOI

Filtering airborne laser scanning data with morphological methods

TL;DR: The experimental test results show that this method performs well for most sites, except those with missing data due to the lack of overlap between swaths, and shows encouraging results for laser data with low pulse density.
Journal ArticleDOI

Above ground biomass estimation in an African tropical forest with lidar and hyperspectral data

TL;DR: In this paper, a Partial Least Square Regression (PLSR) was adopted to cope with multiple inputs and multicollinearity issues; the Variable of Importance in the Projection was calculated to evaluate importance of individual predictors for biomass.
