MapkmlPSU: Creates *.kml files of a subset of polygons from a polygon shapefile

Description

Subset the polygons specified in psu and creates *.kml files of theses polygons.

Usage

MapkmlPSU(shape = NULL, psu = NULL, id = NULL,
  path = "./psu_maps/")

Arguments

shape

string with the path of a polygon shapefile or an object of class sf (see examples).

psu

polygons to subset.

id

column of the *.dbf file with the values to be matched against.

path

class character with the path in which maps will be saved. If the path already exists, it will be overwrited.

Value

*.kml files of the subsetted polygons.

Details

If there are *.kml files in the working directory, the new created files will overwrite it in case of name matching.

shape must receive a shapefile with appropriate coordinate reference system, otherwise, MapkmlPSU report an error.

Examples

# NOT RUN {
data("psu_ssu")

# Take a sample of 5 PSU.
(selected_psu <- SamplePPS(psu.ssu = psu_ssu, psu = 5))
 
## Define shape from shapefile.
shp_path <- system.file("extdata/35SEE250GC_SIR.shp", package="capm")
# The code above used a shapefile avaliable in the
# capm package.
# You might want to write a code like:
# shp.path  <- 'path_to_the_folder_with_the_shapefile'
 
# Create *kml files of 10 polygons.
# }
# NOT RUN {
MapkmlPSU(shape = shp_path,
         psu = selected_psu[, "selected_psu"],
         id = "CD_GEOCODI")

## Define the shape argument as an object x of class sf.
x <- read_sf(shp_path)
MapkmlPSU(shape = x, psu = selected_psu[, "selected_psu"], id = "CD_GEOCODI")
# }
# NOT RUN {
# }
