fullChainSawIZ-class: Class '"fullChainSawIZ"'
In sampSurf: Sampling Surface Simulation for Areal Sampling Methods

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

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

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.

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

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

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.
