Estimation of Tree Positions from Aerial Photos
To estimate positions of individual trees in high– resolution aerial photographs we use circular templates derived from an optical tree crown model and the geometry at image acquisition. Local maxima are found for the correlation function for the successively transposed templates over the whole image. Using auxilliary information on the exact or approximate number of trees in the stand regarded...
متن کاملEstimation of Aboveground Biomass Using Manual Stereo Viewing of Digital Aerial Photographs in Tropical Seasonal Forest
The objectives of this study are to: (1) evaluate accuracy of tree height measurements of manual stereo viewing on a computer display using digital aerial photographs compared with airborne LiDAR height measurements; and (2) develop an empirical model to estimate stand-level aboveground biomass with variables derived from manual stereo viewing on the computer display in a Cambodian tropical sea...

متن کاملTree-Bole Volume Estimation on Standing Pine Trees Using Cascade Correlation Artificial Neural Network Models
Total tree volume estimation is an integral part of forest growth and yield forecasting. Complex formulae are used to estimate bole volume by section, based on relationships proposed by Huber, Smalian and Newton. All these relationships require many measurements of bole diameters at certain heights that are difficult to obtain on standing trees especially when diameter measurements have to be t...
متن کاملMapping Aboveground Biomass using Texture Indices from Aerial Photos in a Temperate Forest of Northeastern China
Optical remote sensing data have been considered to display signal saturation phenomena in regions of high aboveground biomass (AGB) and multi-storied forest canopies. However, some recent studies using texture indices derived from optical remote sensing data via the Fourier-based textural ordination (FOTO) approach have provided promising results without saturation problems for some tropical f...
