Map WKT geometry (points and polygons)

`map_wkt()` takes a well-known text (WKT) geometry column and maps points and polygons onto a gray leaflet map. All NA geometry is dropped before mapping.

map_wkt(
  df,
  wellknowntext = "footprintWKT",
  type = "all",
  remove.duplicates = TRUE
)

Arguments

df: - The name of the data frame that contains WKT geometry.
wellknowntext: - The name of the specific column within the data frame that contains the WKT geometry. This parameter is currently not fully implemented and defaults to the Darwin Core 'footprintsWKT'.
type: - Pick one from "points", "polygons", or "all" to map specific geometry types.
remove.duplicates: - Boolean (TRUE or FALSE). Whether or not to remove identical geometries before plotting.

Value

The function returns a dynamic, zoomable leaflet map with the specific geometry plotted.

Details

Define your dataframe, the column that contains WKT, and an option to map specific geometry types.

Examples

if (FALSE) { # \dontrun{
#map species observations
map_wkt(my_NPS_species_obs)

#map species observations - points only
map_wkt(my_NPS_species_obs, wellknowntext = "footprintWKT", type = "points")
} # }
