CODs

  • are authoritative reference datasets needed to support operations and decision-making for all actors in a humanitarian response.

  • pertain to a recognized country or territory1.

  • are standardized datasets that are commonly used and referenced by all operations.

  • are of four types of COD2:

    • 1: administrative boundaries (COD-AB) and 2: edge-matched administrative boundaries (COD-EM) available in various Geographic Information System (GIS) formats, and accompanying gazetteers

    • 3: population statistics (COD-PS) available as .xlsx and .csv tables, and accompanying gazetteers

    • 4: country-specific (COD-CS) available in relevant formats.

  • reflect the local hierarchical administrative structure,2 are annotated with place names and P-codes, and are generally accompanied by a tabular gazetteer.

  • are best available datasets that ensure consistency and simplify the management of key data.

  • are accepted in country3 or in their region by the relevant Information Management Working Group.

  • are catalogued at the COD Portal [LINK SUBJECT TO CHANGE SOON].

  • are disseminated at the Humanitarian Data Exchange (HDX). ; COD-AB and COD-EM datasets are also available as live GIS geoservices.

  • enable consistency and harmonization among actors working on humanitarian preparedness and response by providing:

    • a common operational picture of the crisis

    • a geographic framework (P-codes) for data collection, analysis, and visualization.

  • are available in two quality classifications:

    • ‘enhanced CODs’ with full quality control, compatibility, and reliability

    • ‘standard CODs’ not yet fully quality controlled.

  • facilitate informed decision making both pre- and post-crisis.

  • reduce duplication of work on baseline data by partnering organizations.

  • strengthen valuable humanitarian networks and relationships.

  • drive API look-up information

1 CODs are generally prepared for sovereign states recognized by the UN Secretariat, but in some cases reflect sub-national territories. For example, there are CODs for Puerto Rico, which is a part of USA, but not for Taiwan, which is not a recognized member state.

2 Previously a ‘Humanitarian Profile’ COD-HP type existed, which presented tabular People-in-Need information derived from Humanitarian Needs Overviews. This information is now provided in country-specific ‘Humanitarian Needs’ (non-COD) datasets disseminated in HDX by OCHA Humanitarian Programme Cycle Tools (HPC Tools). For further information see HPC Tools.

Terminology

Term

Explanation

Administrative level

CODs (and administrative structures) are hierarchical with administrative levels numbered from zero (the entire country or territory) down as far as appropriate. Because the names of administrative levels vary so much between countries and territories, and because a particular country and administrative level may contain features of more than one administrative type, the generic term ‘administrative level’ is preferred in COD management. Administrative levels may be abbreviated ADM1 etc.

Administrative structure

The heart of any COD is its adherence to and echoing of the accepted administrative structure of the country or territory. The administrative structure of a country or territory consists of the administrative features comprising each administrative level.

Country-Specific COD

Feature

An individual geographic unit within the set of units comprising an administrative level in a COD. For instance “California” is an administrative level 1 feature in USA.

P-code

There are four general types of COD:

There are two quality levels of COD:

  • Enhanced CODs

  • Standard CODs

P-codes

CODs for a particular country should be linked by P-codes to each other and to other humanitarian data.

Suggested styling. It is recommended that feature names be contained in quotes and P-codes be contained in square brackets. For instance:

“Lavengatonga” [TO1407]

Enhanced CODs

Enhanced CODs have undergone improved development and quality control. Enhanced COD-AB and COD-EM datasets have been quality controlled and standardized by ITOS. Enhanced COD-PS datasets have been prepared (and therefore quality controlled and standardized) by UNFPA. Enhanced CODs are identified in HDX datasets views and on their HDX dataset pages with a “COD+” icon.

Most new or recently updated COD-AB, COD-EM, and COD-PS datasets are enhanced.

Standard CODs

Standard CODs are those that are not Enhanced. These include older COD-AB datasets, older COD-PS datasets (not contributed by UNFPA), and all COD-CS datasets.

Standard CODs are identified in HDX dataset views and on their HDX dataset pages with a “COD” icon.

Finding CODs

CODs are available for download from the Humanitarian Data Exchange (HDX). Approximately six hundred HDX datasets are CODs. All HDX dataset views contain a filter near the top-left for all CODs and a sub-filter for “Standard CODs” and “Enhanced CODs”. (These distinctions are described below.)

image-20241001-195140.png

All COD datasets visible in any HDX dataset view have a “COD” icon (for Standard CODs) or a “COD+” icon for Enhanced CODs.

image-20241001-195850.png

HDX provides a ‘Common Operational Database’ page (found in the “PRODUCTS” pull-down near the top of any page) which is merely a dataset view of CODs held on HDX.

HDX datasets contain ‘Data and Resources’ and ‘Metadata’. The Data and Resources are the actual files (shapefiles, spreadsheets, etc.) or external links (ITOS live geoservices) comprising a COD. Resources can be individually downloaded.
