Description

Read coastline data stored in the openstreetmap format [1].

Usage

3
read.coastline.openstreetmap(file, lonlim = c(-180, 180),
  latlim = c(-90, 90), debug = getOption("oceDebug"),
  monitor = FALSE, processingLog)

Arguments

file

name of file containing coastline data (a file ending in .shp) or a zipfile that contains such a file, with a corresponding name. The second scheme is useful for files downloaded from the NaturalEarth website [2].

lonlim

numerical vectors specifying the west and east edges (and south and north edges) of a focus window. Coastline polygons that do not intersect the defined box are skipped, which can be useful in narrowing high-resolution world-scale data to a local application.

latlim

numerical vectors specifying the west and east edges (and south and north edges) of a focus window. Coastline polygons that do not intersect the defined box are skipped, which can be useful in narrowing high-resolution world-scale data to a local application.

debug

set to TRUE to print information about the header, etc.

monitor

Logical indicating whether to print an indication of progress through the file.

processingLog

if provided, the action item to be stored in the log. (Typically only provided for internal calls; the default that it provides is better for normal calls by a user.)

Value

An object of coastline-class
