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 correspondingforest
will be empty.
Value
An sf object including a 'forest' column. If keepUnfilteredCopy=TRUE
an additional column 'forest_unfiltered' is also given.
