Purpose of CODs

CODs are authoritative reference datasets needed to support operations and decision-making for all actors in a humanitarian response. CODs are 'best available' datasets that ensure consistency and simplify the discovery and exchange of key data. Core CODs are required in all disaster-prone countries as a preparedness measure, including administrative boundaries, sex and age disaggregated population data and humanitarian profile (caseload).

Core CODs are critical for information and data products and to underpin effective coordination. They are essential for effective risk analysis, needs assessment, decision-making, and reporting by OCHA and partners on all aspects of the response. Of these, the most critical datasets to support response are the basic administrative boundaries and population data. This data is typically provided by the government or national authority.

Other CODs are defined at a country-level based on local hazards and operational requirements. Examples include key infrastructure that could be impacted or used during relief operations such as schools, health facilities, and refugee camps; or topographical data such as rivers, land cover, and elevation. This technical support package recommends CODs for each disaster type as well as detailed technical information on each dataset to help ensure they meet minimum standards for quality and accuracy.
