auditDistances: Audit distances in a record metadata table.

In gmsp: Ground Motion Signal Processing

Audit distances in a record metadata table.

Description

Flags each row with the FIRST applicable reason from a fixed precedence: lat/lon NA, lat/lon out of range, depth negative, Repi above outlier threshold, Rhyp < Repi (geometric impossibility). Rows with no issue are dropped from the output.

Usage

auditDistances(DT, repiOutlier = 5000)

Arguments

DT	record metadata data.table.
repiOutlier	threshold in km above which Repi is flagged (default 5000).

Details

Does NOT read record.json or provider flatfiles. Comparison against raw/flatfile distances is deferred to v2.

Value

data.table of flagged rows with column Reason.

Examples

x <- data.table::data.table(
  EventLatitude = c(0, 95),
  EventLongitude = c(0, 0),
  StationLatitude = c(0.1, 0.1),
  StationLongitude = c(0.1, 0.1),
  EventDepth = c(10, 10),
  Repi = c(15, 20),
  Rhyp = c(18, 25)
)
auditDistances(x)
