mapoland-package: Maps of Poland
In mbojan/mapoland: Maps of Poland for data visualization and graphics

Description Details Spatial data on Poland Author(s) References See Also Examples

This package contains data and tools for drawing maps of Poland.

Tools are provided for drawing data on administrative maps of Poland. Functions rely on functionality of packages sp and maptools. See help(package="mapoland") for the complete list of functions.

The package currently contains data on voivodships, i.e. top-level administrative units. Future releases might include data on county and municipality levels. See Section "Spatial data on Poland" below for information about included shape files.

We have invested some time and effort in creating this package. We hope that it will be useful to you. Please cite it whenever you use it for data analysis or other tasks. See citation(package="mapoland") for the proper information and format.

Package mapoland provides some extra data files with spatial information about Poland. These are in ESRI shape files stored in the shapes folder of the package directory.

The policy that is implemented in package mapoland is to:

Store polygon data in shape files instead of in R images (rda files) of objects of class SpatialPolygonsDataFrame. The user can easily import them using getShape function in this package.
Limit the number of polygon attributes in the shape files to absolute minimum necessary for identifying the polygons. Currently the polygons can be identified with TERYT codes as well as area names in various encodings, see sections below for details.
All additional polygon attributes are stored in separate data frames, to be loaded with data. They can be matched with the polygons "on the fly" as well as used for other purposes.

Quick list of available shape files (see sections below for details):

polska.shp: low-quality contour of Poland
voiv.shp: low-quality polygons for Polish voivodships

See section "Accessing the shape files" at the end for how to get your hands on the data.

Contour of Poland (polska.shp)

File:	`polska.shp`
Source:	Unknown

This is a simple low-quality contour of Poland. Very usefull for presentation purposes, not for any serious geo-/spatial purposes. Point coordinates do not have any geographical interpretation and the projection is unknown. The shape file does not contain any polygon attributes.
