Openness rating:

The Teagasc Subsoils map classifies the subsoils of Ireland into 16 themes, using digital stereo photogrammetry supported by field work. Produced by Teagasc (Kinsealy), EPA and GSI.

Provenance information The dataset was created using a compilation of existing data, photogrammetric mapping, field studies. Soil survey maps, Quaternary maps and published and unpublished reports were complied and boundaries between sediment types are interpreted and mapped using photo-interpretation in a soft copy photogrammetric workstation with digital stereo-pairs of black and white photography acquired at a scale of 1:40,000. Fieldwork was carried out, around the flanks of large bogs delineate the exact boundary between peat and mineral soils but predominantly within the boundary zones of differencing subsoils. Areas mapped during the photogrammetric analysis were also checked during the fieldwork. Methods adopted during field mapping include reconnaissance mapping, auger sampling, trenching, digital photography and GPS data recording. Aerial photography datasets involved in mapping were acquired in 1995 while field data collected was collected during 1998-2005.The classification of subsoils is based on the classification used by the Geological Survey of Ireland Quaternary Section in mapping Quaternary sediment types.This classification has been altered only to ensure utility specific to the requirements of the EPA Soil and Subsoil Mapping Project.
