title: Prediction of board MOE from increment cores - data

description: <br>
description: Data from 68 southern pine hybrid trees (Pinus elliottii var. elliottii x P. caribaea var. hondurensis) sampled in southern Queensland (note no data exists for tree 61, hence tree numbers range from 1 to 69). The trees were collected from three sites in the southeast Queensland plantation estate owned by HQPlantations. Tree sizes were stratified by diameter at breast height, to ensure we collected the full range of sizes in the plantations. Ages of the trees ranged from 19 to 28 years.

description: 6 variables in columns and 635 lines of hybrid pine data:
description: 1. Tree#: Identifier for the tree
description: 2. Stud centre distance from pith (mm): Distance from the pith to the centre of the board
description: 3. Log end: The end of the log from which the static bending sample was taken. Butt end = 0, Top end = 1.
description: 4. Static bending MOE: The standard reference MOE measured using the four-point bending test.
description: 5. Predicted MOE - 3D approach: The board MOE predicted from our three-dimensional approach using four diametrical cores extracted from the tree.
description: 6. The board MOE predicted from our two-dimensional approach using a single diametrical core extracted near breast height.

description: 9 variables in columns and 3184 lines of hybrid pine data:
description: 1. Tree#: Identifier for the tree
description: 2. Stocking: Number of stems per hectare
description: 3. Height Core#: The core number extracted from the log, from 1 (butt end) to 4 (top end).
description: 4. Side#: The side of the pith the segment was taken from.
description: 5. Segment Position#: Segment count from each side of the pith, starting from 1 (near bark).
description: 6. Segment#: Overall segment number. Note some segments were rejected hence maximum segment number is 3204.
description: 7. Distance Seg from pith (Matlab): Distance from the pith to the centre of the segment, calculated using image processing in Matlab.
description: 8. Height (m): Height of the core in the tree.
description: 9. Segment US MOE: Segment MOE (in MPa) measured using the ultrasound method.
