Objective

The Objectives of this task group is to provide the UN community, and when possible the international community, with validated information and maps regarding international and administrative boundaries for all the UN member countries.

Activities

This task groups work on collecting and compiling all the information and maps available regarding international and administrative boundaries in close collaboration with the governmental bodies in the countries.

The International Boundaries project offers a 1.1 million-scale dataset, which reflect the cartography practice of the UN cartographic Section for the representation of International Boundaries. A 5 million and a 10 million-scale dataset are under development.

Due to the sensitivity linked to international boundaries, this layer is only accessible to the UN community from http://boundaries.ungiwg.org/

Regarding the administrative boundaries, the Second Administrative Level Boundaries project (SALB) launched in 2001 provide the following information and data validated by the National Mapping Agencies of the respective countries:

	The historic changes observed since 1990 at the 1st sub national level and since 2000 at the 2nd sub national level as well as well as maps
	2nd administrative level digital maps (ESRI format) for each period of representativity observed since January 2000

This project has also lead to the development of a specific coding scheme that allows the management of sub national data through time and space.

More details about this project, the coding scheme, as well as the data already available can be downloaded from the SALB web site at http://www3.who.int/whosis/gis/salb/salb_home.htm
