The Grain Size Distribution Estimator Tool is located under the Analysis menu and further the Roughness Analysis menu:
A video tutorial for how to use the Grain Size Distribution Calculator can be seen below:
When the Grain Size Distribution Calculator is run, the following dialog appears:
The inputs for this tool are:
Surface roughness raster
raster representing surface roughness. With high density data it is recommended to create this raster with the Simple ToPCAT Roughness Tool.
Vertical units of surface roughness raster
Channel unit polygon
Polygon feature class representing areas of interest where the grain size metrics of D16, D50, D84, and D90 will be calculated for.
Unique channel Field
Append grain size metrics (optional)
if this check box is selected then the grain size metrics of D16, D50, D84, and D90 will be appended to the channel unit polygon
Append number of raster cells (optional)
The outputs for the tool are:
- Create cumulative distribution plot
