Waveforms from the Ice, Cloud and land Elevation Satellite have successfully estimated footprint-level canopy height and aboveground biomass even in structurally complex savanna ecosystems. However, at the landscape level wall-to-wall maps are preferred since they are more easily integrated with other geospatial data products. We evaluated and compared the utility of inverse distance weighting, cokriging,...
Research in Australia has focused on using the combination of moderate (25–30 m) spatial resolution ALOS PALSAR, Landsat-derived persistent green fractional cover and ICESAT GLAS data to generate maps of the structure of forests as an intermediate step to mapping above ground biomass (AGB) and AGB change using combinations of JERS-1 SAR, ALOS PALSAR and ALOS-2 PALSAR-2 data. The method involved a)...
Detailed tree information, such as tree counts, tree heights, crown base heights, diameter at breast height (DBH), and tree biomass, is critical for the effective management and quantitative analysis of trees in urban area. Automatic detection of trees, and their parameters using light detection and ranging (LiDAR) data has been widely employed. However, at the single-tree level along road in urban...
Lidar (light detection and ranging) remote sensing can accurately characterize forest vertical structure, such as canopy height, above-ground biomass (AGB) and timber volume; however, data acquisition is expensive. To reduce costs, one potential method is to integrate (small area) lidar transects and (large extent) optical imagery to estimate forest characteristics. Typically, multiple regression...
