SCIMAP aids spatial targeting by identifying the locations in the landscape that are most likely to be contributing to an observed diffuse pollution issue. SCIMAP should be used as part of a toolkit whereby a suitable large-scale catchment (e.g. 2000 km2) has been identified as having a water quality issues thought to be related to diffuse pollution. SCIMAP can then identify the key locations within this landscape where the combination of connectivity and source risks lead to a probable source. These locations can then be investigated in more detail on the ground since there may be features not represented in the input data. At the end of this process, SCIMAP can identify the sub-catchments, field and flow paths within the fields, at the scale of five metres or less, that are of high risk of exporting diffuse pollution.
