Auxiliary data provide supplementary or additional help and support to core [[Items Pane|items]] and include country structure, ordnance, organisations, places, assistance classification, cause classification and needs classification.
The country structure represents a gazetteer, or the political or administrative divisions within a country. In IMSMA<sup>NG</sup>, the country structure allows a mine action programme to link mine action information to areas and report statistics such as number of hazards per province or district. So the country structure should be set up before beginning data entry.
