Second Administrative Level Boundaries

Geospatial Information Section & Statistics Division



Launched in 2001, the SALB initiative started under the impulse of the United Nations Geographic Information Working Group (UNGIWG) and was initially led and implemented by the World Health Organization (WHO). The overall concept, methodology and objectives were elaborated during this period and allowed to start the collection of geospatial datasets and historical changes as well as National Geospatial Information Authorities contact details.

In 2011, SALB was transferred under the direction of the United Nations Secretariat and jointly managed by the Geospatial Information Section, formerly Cartographic Section, of the Office of Information and Communications Technology (OICT) and the Statistics Division of the Department of Economic and Social Affairs (DESA). These offices are also responsible to act as the Secretariat (See Annex of resolution 2011/89, para 6) for the United Nations Committee of Experts on Global Geospatial Information Management (UN-GGIM).

The SALB programme wishes to thank all United Nations entities, institutions, projects, commissions, committee or networks without whom SALB would not exist.

SALB regional partners

The SALB programme relies on 5 main continental-based regional partners which play a crucial role at all stage of the process by providing advocacy, technical support, data processing, contact details updates and allow for a close cooperation with the National Geospatial/Mapping Agencies responsible for administrative boundaries and names.

The 5 regional partners of SALB are:

For Africa: Economic Commission for Africa of the United Nations, Geo-information Systems Section

For Asia & Pacific: To be determined
For the Americas: Instituto Panamericano de Geografía e Historia (IPGH)
email: /
For Arab States: To be determined
For Europe: EuroGeographics 

National Mapping Agencies

The National Mapping Agencies are at the core of the SALB programme as they provide the authoritative source information on administrative boundaries. The SALB programme is merely a conduit which allows the authoritative information on administrative boundaries and names to be collected, compiled and disseminated to the international community.

SALB wishes to thank all the participating National Mapping Agencies for their contribution including technical guidance, multi-lateral cooperation, advocacy and outreach for geospatial information and data contributions.
