Item Identification

Title: R-Factor for the Island of Maui
Short Name: R-Factor_metadata_for_Island_of_Maui
Status: Completed
Publication Date: 2013-12-26
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 Maui 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).

Data Quality

Accuracy:

The cell values in this product represent R-Factor which is an erosivity index for rainfall and runoff. The units are (hundreds ft-tonf-in)/(ac-h-yr).

Horizontal Positional Accuracy:

This map is an approximation of spatial rainfall-runoff values

Vertical Positional Accuracy:

None

Completeness Measure:

Cloud Cover: 0

Completeness Report:

All pixels within the Island of Maui boundary contain R-Factor values.

Conceptual Consistency:

Tests for logical consistency indicate that all row and column positions in the selected latitude/longitude window contain data. Conversion and integration with vector files indicates that all positions are consistent with earth coordinates covering the same area.

Process Steps

Process Step 1

CC ID: 625666
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.
