  visualizeVariables,
  lon_bounds,
  lat_bounds,
  image_def,
  ihsf
)

Arguments

visualizeVariables

A dataframe containing $lon and $lat values which will be bounded by lon/lat_bounds (data.frame).

lon_bounds

Array containing two values for longitude min and max (numeric).

lat_bounds

Array containing two values for latitude min and max (numeric).

image_def
