check_adv: performs user-specified checks on adv data

In USGS-R/GDopp: processing of ADV data

Description

checks data for various quality metrics

Usage

check_adv(chunk.adv, tests = "all", verbose = FALSE, ...)

Arguments

chunk.adv	a data.frame created with load.ADV, with the window.idx column
tests	a character array of test names, or 'all' to run all tests
verbose	boolean for diagnostic print outs
...	additional args passed to check functions

Details

a GDopp function for checking data quality.

Value

failed, T or F

data.adv <- load_adv(file.nm=file.nm, folder.nm =folder.nm)
window.adv <- window_adv(data.adv,freq=32,window.mins=10)

check_adv(chunk.adv,tests = 'beam.correlation_check_adv', verbose=TRUE, correlation_threshold = 95)
## low threshold
check_adv(chunk.adv,tests = 'beam.correlation_check_adv', verbose=TRUE, correlation_threshold = 55)

check_adv(chunk.adv,tests = 'signal.noise_check_adv', verbose=TRUE, signal_threshold = 15)
## higher ratio requirement
check_adv(chunk.adv,tests = 'signal.noise_check_adv', verbose=TRUE, signal_threshold = 50)
