Map units (MUSYM): 7085, 7083, 7085b
report version 2.3
2017-04-14


This report is designed to provide statistical summaries of the environmental properties for one or more map units. Summaries are based on raster data extracted from fixed-density sampling of map unit polygons. Please see the document titled R-Based Map Unit Summary Report Introduction and Description for background and setup.

Area Summaries

Target sampling density: 1 points/ac. defined in config.R. Consider increasing if there are unsampled polygons or if the number of samples is less than about 200. Note that the mean sampling density (per polygon) will always be slightly lower than the target sampling density, depending on polygon shape.

Modified Box and Whisker Plots

Whiskers extend from the 5th to 95th percentiles, the body represents the 25th through 75th percentiles, and the dot is the 50th percentile. Notches (if enabled) represent an approximate confidence interval around the median, adjusted for spatial autocorrelation. Overlapping notches suggest that median values are not significantly different. This feature can be enabled by setting correct.sample.size=TRUE in config.R.

Suggested usage:

Density Plots

These plots are a smooth alternative (denisty estimation) to the classic "binned" (histogram) approach to visualizing distributions. Peaks correspond to values that are most frequent within a data set. Each data set (ID / variable) are rescaled to {0,1} so that the y-axis can be interpreted as the "relative proportion of samples".

Suggested usage:

Tabular Summaries

Table of select percentiles, by variable. In these tables, headings like "Q5" can be interpreted as the the "5th percentile"; 5% of the data are less than this value. The 50th percentile ("Q50") is the median.

Slope Aspect

A graphical summary of slope aspect values using density and percentile estimation methods adapted to circular data. Spread and central tendency are depicted with a combination of (circular) kernel density estimate (dashed blue lines) and arrows. The 50th percentile value is shown with a red arrow and the 10th and 90th percentile values are shown with gray arrows. Arrow length is proportional to the strength of directionality. Use the figures and table below to determine "clockwise" / "counter clockwise" values for NASIS component records.

Slope Shape (Curvature) Summary

The classes were generated using a 5x5 moving window, from a regional 30m or 10m, integer DEM. The precision may be limited, use with caution. See instructions for using your own (higher resolution) curvature classification raster.

Geomorphon Landform Classification

Proportion of samples within each map unit that correspond to 1 of 10 possible landform positions, as generated via geomorphon algorithm. Landform classification by this method is scale-invariant and is therefore not affected by computational window size selection.
