fullChainSawIZ-class: Class '"fullChainSawIZ"'

Description Objects from the Class Slots Extends Methods Note Author(s) References See Also Examples

Description

This class holds the inclusion zone definition for the full ‘chainsaw’ method (Gove and Van Deusen, 2011) for sampling down coarse woody debris.

Objects from the Class

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

Slots

This class is a direct subclass of “sausageIZ” and adds no new slots. Please see "sausageIZ" class definition for details.

Extends

Class "sausageIZ", directly.
Class "downLogIZ", by class "sausageIZ", distance 2.
Class "InclusionZone", by class "sausageIZ", distance 3.

Methods

izGrid

signature(izObject = "fullChainSawIZ", tract = "Tract"): Used in sampling surface construction.

Note

The inclusion zone for the full chainsaw method is the sausage inclusion zone, but it is given its own class here so that we are later able to use it as a signature argument for actually constructing the sampling surface. Each grid cell within the inclusion zone will have its estimate determined based on the "chainSawIZ" method for fixed-area plots, which produces a variable surface. All estimates for this method are unbiased with the exception of Density, which can have severe bias. The sausage method must be used to get unbiased estimates of this attribute. See the reference below for more details.
