parse_forestable: Parse forestable

In emf-creaf/medfateland: Mediterranean Landscape Simulation

Parse forestable

Description

Transforms a data frame or sf object issued from package forestables into an sf object for simulations with medfateland.

Usage

parse_forestable(
  x,
  keepSpeciesCodes = TRUE,
  filterMissingSpecies = TRUE,
  filterDeadTrees = TRUE,
  filterCutTrees = TRUE,
  keepUnfilteredCopy = FALSE,
  minimumTreeDBH = 0.1,
  progress = FALSE
)

Arguments

x	A data frame or sf object issued from package forestables.
keepSpeciesCodes	Keeps forest inventory species codes.
filterMissingSpecies	If TRUE, filters out records where species is missing.
filterDeadTrees	If TRUE, filters out dead trees (Spanish forest inventory IFN3 or IFN4).
filterCutTrees	If TRUE, filters out cut trees (Spanish forest inventory IFN3 or IFN4).
keepUnfilteredCopy	If TRUE, an additional column is given where dead/cut trees have not been filtered.
minimumTreeDBH	Minimum DBH for keeping a tree record.
progress	A logical flag to include a progress bar while processing the data.

Details

This function retrieves the following information from the forestables object:

• Id unique code, survey year, non-unique plot code and country.

• Plot location. Output geometry is always points in WGS 84. Note that exact coordinates are not normally given in forest inventory data.

• Elevation, slope and aspect, whenever available

• Tree and understory data. The function will create a column forest with this information. If both tree and understory data are missing for a given row, the corresponding forest will be empty.

Value

An sf object including a 'forest' column. If keepUnfilteredCopy=TRUE an additional column 'forest_unfiltered' is also given.
