WOODLOT for Windows 2.1 - Reference Manual
12.0 Calculation
The Calculations screen is used to perform harvest rate calculations. An iterative calculation is performed on all selected polygons. A harvest rate is calculated over the planning horizon (usually 250 years), though the planning horizon can be changed in the Summary screen.

Calculations are carried out based on data compiled from the Polygon Data screen, and harvest parameters set by polygon and woodlot.

This screen has an application menu bar with File, Sort, Rate and Graph. Also, notice in lighter blue the headings for each function in the Calculations screen. Basic functions discussed below include:
  • Application menu bar with File, Sort, Rate and Graph
  • Harvest Order
  • Constraints
  • Calculate
  • Harvest schedule
  • Standing Volume/Time graph
