importanceCHSIZ-class: Class "importanceCHSIZ"

Description

This class holds the inclusion zone definition for the importance sampling variant/protocol of critical height sampling for standing trees.

Objects from the Class

Objects can be created by calls of the form new("importanceCHSIZ", ...). However, this is not recommended because the objects are fairly complex. Instead, one can use the object constructor "importanceCHSIZ" to create new objects.

Slots

This class is a subclass of “criticalHeightIZ” (see below). It adds no new slots to the definition of that class, so please refer to it for the slot definitions.

Extends

Class "'>criticalHeightIZ", directly. Class "'>horizontalPointIZ", by class "criticalHeightIZ", distance 2. Class "'>circularPlotIZ", by class "criticalHeightIZ", distance 3. Class "'>standingTreeIZ", by class "criticalHeightIZ", distance 4. Class "'>InclusionZone", by class "criticalHeightIZ", distance 5.

Methods

izGrid

signature(izObject = "importanceCHSIZ", tract = "Tract"): “InclusionZoneGrid” constructor
