Users need to understand the key hydrological processes within their area of interest and basic GIS skills. The user needs to understand what the results are saying and to ensure that the assumptions fit with… Expertise needed to run SCIMAP
The key limitation with an application of SCIMAP is the quality of the input data (garbage in, garbage out). Therefore, care must be taken to use datasets with the required level of spatial information. Many… Limitations of SCIMAP
The standard implementation of the SCIMAP framework is applicable where the topographic controls dominate the movement of water and pollutants through the landscape. Therefore, SCIMAP is widely applicable in many parts of the UK. However,… Where is SCIMAP applicable?
SCIMAP can be run across large catchment (2000 km2 +) as well as for targeted sub-catchments (e.g. < 1km2). The normal grid resolution is 5m based on the NextMap DTM product therefore giving large coverage… What are the scale and data requirements for SCIMAP?
SCIMAP is based on the identification of locations of critical source areas (Heathwaite et al. 2005). within the landscape. These locations are based on the areas that are most likely to have a source of… What is the scientific basis of SCIMAP?
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… How SCIMAP aids the spatial targeting of diffuse pollution mitigation measures
SCIMAP is a risk-mapping framework designed to identify where in the landscape diffuse pollution is most likely to be originating. SCIMAP does not try to make quantitative predictions in real world units (e.g. mg l-1)… Basic description of the SCIMAP framework
If you are using the current CEH Land Cover Map 2007 (LCM2007), then the standard reclassification table that is used in SCIMAP will not work because CEH changed how they coded the different land cover… Land cover erosion risk weights and LCM2007
Sometimes the output from SCIMAP (SAGA GIS version) is not as expected and features strange contour line like features.Strange contours in SCIMAP output
A common error when first installing SAGA-GIS and the SCIMAP module is: “Failed to load shared library ‘…saga_vc8/modules/scimap.dll’ (error 126: the specified module could not be found.). The normal reason for this problem is missing… Failed to load shared library error solution
