Name: ICPRB Drinking Water Quality Priority

Display Field: VALUE

Type: Raster Layer

Geometry Type: null

Description: <DIV STYLE="text-align:Left;"><DIV><P><SPAN>The raster-scale cumulative prioritization represents the cumulative prioritization value of all metrics. The raster cell values of the seven metric rasters included in this geodatabase were summed using equal weights except for karst transmissivity. Karst transmissivity received a weight of 0.5 (or 50 percent) because the metric tended to dominate all other values where it was present. </SPAN></P><P><SPAN>The raster was normalized on a scale from 0 to 100, with a value of 100 indicating the highest priority for conservation. The “Geomorphometry &amp; Gradient Metrics Toolbox” developed by Evans and Cushman (2014) was used for the normalization procedure. The toolbox is available at https://github.com/jeffreyevans/GradientMetrics. Accessed 3/9/2020.</SPAN></P></DIV></DIV>
