quantify.lu.ecors: Quantify the pixels of each Land Use class

In fredtaka/ecors: Remote Sensing data acquisition and processing for ecology with Google Earth Engine

Quantify the pixels of each Land Use class

Description

Generate tables of number of pixels of each Land Use class in each reference polygon (site, samples, polygons - as defined in function get.lu.ecors) in each year.

Usage

quantify.lu.ecors(
  x,
  save.format = "ods",
  save.metadata = T,
  spreadsheet.folder = getwd()
)

Arguments

x	lu.ecors object (from get.lu.ecors).
save.format	select save results in "ods" or "RData" format (or both). Set to NULL if you do not want to save files.
save.metadata	should save metadadata (txt)?
spreadsheet.folder	local folder to save files.

Value

List with result tables and metadata. If enabled, ods (recomended) or RData files will be saved with result tables an metadata.

Examples

#get a lu.ecors class object
FAL.IBGE.JBB<-sf::st_read(system.file("extdata/FAL.IBGE.JBB.gpkg", package="ecors"))
test.points<-sf::st_read(system.file("extdata/Points_tests.gpkg", package="ecors"))
test.plots<-sf::st_read(system.file("extdata/Plots_tests.gpkg", package="ecors"))

lu2000_2010<-get.lu.ecors(site=FAL.IBGE.JBB, points=test.points, plots=test.plots,
     polygons=NULL, id.column=1, projected=F, custom.crs=32723,
     collection.lu="mapbiomas6", years=c(2000,2010), resolution=30, evaluate="surroundings.samples",
     buffer1=500, buffer2=1000, buffer3=2000, cumulative.surroundings=F)
