The indicative soils map classifies the soils of Ireland on a categorically simplified but cartographically detailed basis into 25 classes, using an expert rule based methodology. Produced by Teagasc (Kinsealy), EPA and GSI.

Provenance information Soil maps are out of practical necessity based on surveyors predicting what soils occur on those parts of the landscape that they cannot visit. Key soil forming factors such as vegetation (landcover), topography and geology (parent material) were mapped and a set of rules were applied to these datasets to predict the soils that may occur at any given location in the landscape. These maps were then combined to create a predicted model of soil occurrence. Combination of these inputs provided for a modelled output of predicted soils, with this model output termed Level 1. The model was then extended to a Level 2 predictive model which incorporated topographical variables, previously mapped soil data and other geologically based variables such as subsoil permeability, which increased map accuracy. Predictions are based on expert judgement in combination with pre-existing, mapped data (National Soil Survey (NSS) 1959-1980's at 1:126720; General Soil Map of Ireland, 1969 and 1980 at 1:575,000, Peatland map 1978). Both GIS and remote sensing technologies were used in the process. The OSI 20m DTM was used as part of the topographic analysis. A soil series is generally named after the locality where it was first identified and the soils that it represents are best expressed.
