Description
Description | Soil Erosion Max Potential - Wind or Water (SA Raster) provides a numeric rating in each raster cell of the potential for erosion by wind or water in the event that vegetation or other ground cover has been removed (e.g. by fire, over-grazing, land clearance). The assessment is based on mapping of terrain and spatial predictions of inherent soil erodibility characteristics. The following erosion potential classes are suggested (but not mandated): 0 - 500 LowSELECT 1 FROM DUAL;
>500 - 3000 Moderately lowSELECT 1 FROM DUAL;
>3000 - 5000 ModerateSELECT 1 FROM DUAL;
>5000 - 6500 Moderately HighSELECT 1 FROM DUAL;
>6500 - 8000 HighSELECT 1 FROM DUAL;
>8000 - 9000 Very highSELECT 1 FROM DUAL;
>9000 - 10000 Extreme. Raster values have been multiplied by the value 10,000 and converted to a 16-BIT (pixel depth) unsigned integer (pixel type) to reduce file size. To convert the integer values back to the 0-1 continuous scoring system (32-BIT floating point) divide values by 10,000. |
Usage | This dataset is for use in landscape biophysical modelling that requires fine-resolution estimates of the potential (inherent susceptibility) of land for soil erosion by either wind or water (based on terrain and stability of soil profiles), assuming that protective vegetation or other ground cover has been removed. Sample map can be downloaded from Enviro Data SA. Spatial data download is available from Data SA. |

Data Quality
Lineage | This dataset is derived from taking the maximum value in each raster cell of either (1) Water Erosion Potential (SA Raster), or (2) Wind Erosion Potential (SA Raster). The lineage of these respective data layers are provided in the links provided. |
Completeness | Complete. The spatial data is subject to amendment as and when more data become available. |
Positional Accuracy | Estimated accuracy is 50 metres. Accuracy cannot be assumed at the paddock level. |
