l4_convert: Convert GEDI level 4A data to 'sf' object and export it

In VangiElia/GEDI4R: What the Package Does (One Line, Title Case)

Convert GEDI level 4A data to sf object and export it

Description

Write GEDI level 4A data to disk as a vector file.

Usage

l4_convert(gediL4, epsg = NULL, filename, return_path = F, ...)

Arguments

gediL4	data.table obtained with the function l4_getmulti() or l4_clip, or a SpatVector object.
epsg	Numeric: destination EPSG code. Default to NULL.
filename	Character: path to data source name. Usually a file name with extension. See ?writeVector for more details.
return_path	Logical: if TRUE, the path of the saved file will be returned, otherwise the function will return NULL. Default to FALSE.
...	Others argument to pass to writeVector, such as filetype or overwrite

Details

If a file extension will cause conflict with the filetype, the extension will be guessed from the file name. Note that in converting data to ESRI Shapefile, columns names will be abbreviated.

Value

The function is called for its side effects. It return NULL unless return_path=TRUE.

                     "GEDI04_A_2020036151358_O06515_02_T00198_02_002_01_V002.zip",
                     package="GEDI4R")
l4 <- unzip(l4_zip,exdir = outdir)
#get GEDI data
l4_data <- l4_getmulti(l4)
#convert to shp file
converted <- l4_convert(l4_data,epsg = 4326,filename=paste0(outdir,"/example.shp"),return_path = T)
example <- terra::vect(converted)
file.remove(list.files(outdir,pattern = "example",full.names = T))
