| Abstract: |
The rainfall-runoff erosivity factor (R-Factor) quantifies the effects of raindrop impacts and reflects the amount and rate of runoff associated with the rain. The R-factor is one of the parameters used by the Revised Unified Soil Loss Equation (RUSLE) to estimate annual rates of erosion. This product is a raster representation of R-Factor derived from isoerodent maps published in the Agriculture Handbook Number 703 (Renard et al.,1997). Lines connecting points of equal rainfall ersoivity are called isoerodents. The iserodents plotted on a map of the Island of Molokai were digitized, then values between these lines were obtained by linear interpolation. The final R-Factor data are in raster GeoTiff format at 30 meter resolution in UTM, Zone 4, GRS80, NAD83. |
| Purpose: |
These data are represented in raster format for use with the Open source Nonpoint Source Pollution and Erosion Comparison Tool (OpenNSPECT). |

Process Steps
Process Step 1
| Description: |
The rainfall-funoff erosivity factor was estimated from the R-Factor maps for the Hawaiian Islands. given in the Agriculture Handbook number 703. A line shapefile approximation of the printed map was generated via "heads-up" digitizing. The final raster map was produced using the Topo to Raster command in ESRI ArcGIS 10.x. |
