​​​​​We have published a 1:250,000 scale Physiographic units map of Ireland viewer and a corresponding data-package.​ Physiographic maps are cartographic representations of the broad-scale physical landscape units of a region. Physiographic units consist of physical regions showing internal uniformity with respect to one or more environmental attributes that can be clearly differentiated from neighbouring regions. The value of physiographic unit maps is becoming increasingly acknowledged, particularly in the fields of regional land-use planning, landscape evolution, and the influence of physical landscape on aspects of the ecological environment. ​

Further information is available in the accompanying report, its appendix​ and from our Land Mapping projects page.
