Silva Calc

Linguistic program for research and school purposes. Performs plot plan drawing at any scale including tree canopy and trunks, stand index calculations, searches and calculations in volume tables.

Description:

• the ability to draw the crown of a tree independently of the trunk
• the ability to define a negative length of the tree crown and thus shift the crown
• off the trunk axis (important for drawing strongly leaning trees)
• the ability to use negative trunk coordinates
• defining crown and trunk colours and sizes separately for each tree
• two-dimensional area visualization
• colour differentiation of trees according to different parameters (height, height grades, thickness, species, etc.)
• drawing of the area at a scalable scale
• drawing the crown of a tree in the shape of four quarter-telips, which best represents the actual shape of the crown
• printing the plan to scale
• calculations used in forestry research with the possibility of further extension
• Survey of stand inventories using built-in volume tables
• option to define your own volume tables or extend existing ones
