fetchKSSL: Fetch KSSL Data (EXPERIMENTAL)

In soilDB: Soil Database Interface

Description

Get KSSL data via BBOX, MLRA, or series name query, from the SoilWeb system.

Usage

fetchKSSL(series=NULL, bbox=NULL, mlra=NULL, pedlabsampnum=NULL, 
pedon_id=NULL, pedon_key=NULL)

Arguments

series	a soil series name, case insensitive
bbox	a bounding box in WGS84 geographic coordinates e.g. c(-120, 37, -122, 38)
mlra	an MLRA ID
pedlabsampnum	KSSL pedon lab sample number
pedon_id	user pedon ID
pedon_key	KSSL internal pedon ID

Details

This is an experimental interface to most of the KSSL data as of June 2015. Series-queries are case insensitive. Series name is based on the "correlated as" field (from KSSL snapshot) when present. The "sampled as" classification was promoted to "correlated as" if the "correlated as" classification was missing.

Value

a SoilProfileCollection object

Note

SoilWeb maintains a snapshot of the KSSL data. The SoilWeb snapshot was developed using methods described here: https://github.com/dylanbeaudette/process-kssl-snapshot. Please use the link below for the live data.

Examples

## Not run: 
# search by series name
s <- fetchKSSL(series='auburn')

# search by bounding-box
# s <- fetchKSSL(bbox=c(-120, 37, -122, 38))

# how many pedons
length(s)

# plot 
par(mar=c(0,0,0,0))
plot(s, name='hzn_desgn', max.depth=150)

## End(Not run)
