Assisi Forest 2023 Updates

Updated: May 11

A list of the more important changes made to Assisi Forest during 2023.

Smaller bug fixes and interface enhancements are not generally listed.

Summaries Added to Table Views


Sums and averages were added to the footer of table views. Now you can directly filter or group by species, etc and see the resulting sum of BA and volume or average of height. If a report does not have the tree size classes summarized as you need, then just filter and group trees within the Inventory Editor and get the values you need.

Example tree list with DBH>=6" and no snags.

The same filtered tree list as above, but grouped by species.

Max DBH Added to Equations


Most equations (volume, height, growth, etc.) have a min DBH criteria. Max DBH has now been added. This is helpful for example when using tree volume equations to calculate board on large trees and cubic on smaller trees.

Note that when volume is calculated and graded using log level equations, the graded volume summaries will already be summed by board or cubic. Also note that some growth equations have large and small tree versions that already have settable transition values. Max DBH just rounds out the options for assigning equations to trees based on DBH size.

Calibration and Market Optional on Cruise Sheet Import


Calibration and Market can now be left empty when importing using the Cruise Sheet Import.

Option to Drop Field Called Sawlog Heights


Sawlog height is the height where sawlog grade volume turns into non sawlog grade volume such as pole, pulp or cords. Calling sawlog height has been common for hardwood surveys for many decades.

However there are times when you may not want to use the field called sawlog heights such as when you want Assisi to segment trees using tree taper. It is often the case that using taper to stop segmentation at a field called sawlog height results in a short log in the remaining sawlog section that will end up as cull rather than sawlog.

This version adds an option to drop field called sawlog heights so that segmentation can continue up the tree to sawlog heights without creating short sawlog lengths. When used with optimized scaling, log lengths will be determined by grade definitions which themselves have criteria that defines sawlog quality logs.

GIS Added to Assisi Forest


GIS layers for stands and plots are formally defined using geometry fields in their respective tables. Stand and Plot layers can be imported using KML format or created using Assisi's GIS editor. Grid or random plot layouts can be created by dropping a cruise design on top of stand polygons. Locations are exported to the field data app, Assisi Cruiser for GPS location in the field.

Assisi Cruiser Updated


Assisi Cruiser has been updated to a new navigation approach and now includes all Assisi Forest data fields.

Grading Min Diameter


Board and cubic diameters are distinct when testing grade min diameter criteria. For grades using board volume, a log's board deducted and scaled diameter is used to match grade min diameter criteria. For grades using cubic volume, the cubic scaled diameter is used.

This version adds actual diameter as a comparison for grades using units of weight, carbon, user or none. Actual diameter is the calculated dib of a log before deductions or scaling.

Grade & Sort Volume Type Fields Removed


The Board Type and Cubic Type fields used by Grades and Sorts tables were an earlier method mapping board or cubic to grade tallies. Value Units and Value Type were introduced later after Carbon, Weight and User tallies were added to Assisi.

Assisi has not used these fields for a while and they are now removed.

Missing Height Checks in Volume Equations


Checks for missing heights required by volume equations were checking height relative to ground for null rather than height as recorded, which can be either relative to ground or relative to stump, for null.

With this version, height as recorded is checked for null. This may result in more trees being flagged for missing heights than in prior versions. This may also result in different volumes for trees where a height was missing and stump was > 1'.
