Version: [3876] GeoBioTool 1.0.4

Changelog for v1.0.4

Added a new “Compute LAI & VCI” processing tool:

Reads an ASCII point-cloud (X/Y/Z) file and divides it into 20 m grid
cells.

For each grid cell, calculates:

LAI (Leaf Area Index) by summing log-ratio values (LAD) across
vertical layers above a 3 m canopy threshold.

VCI (Vertical Complexity Index) as the coefficient of variation of 1
m-bin histograms of canopy returns.

Outputs a CSV file with columns: cell-center Y (yg), cell-center X
(xg), LAI, VCI.

Creates two separate heatmaps:

LAI.PNG (showing grid-cell LAI values)

VCI.PNG (showing grid-cell VCI values)

Updated the main plugin registration (geobiotool.py):

Imported and registered GeoBioToolLAIVCIAlgorithm.

Removed the obsolete geobiotool_height_matrix_algorithm.py reference
(no longer required).

Updated metadata (metadata.txt):

Bumped version to 1.0.4.

Updated description, about, and tags to include “LAI” and “VCI”.
