Check spatial attributes of Sample Station information

This checks for inconsistent placement of stations to flag potentially incorrect location information

Usage

qa_stations_spatial(stations, quant_thresh = 0.9, dist_thresh = NULL)

Arguments

stations

an sf data.frame as read in by read_sample_station_info()

quant_thresh

The quantile above which the distance of a station from the other stations (compared to the average distance between stations) will be flagged as an outlier. Default 0.85.

dist_thresh

The distance (in m) above which the distance of a station from the other stations will be flagged as an outlier. By default the quantile is used, but can be overriden by setting this to a numeric value in metres.

Value

the input data.frame, with a new logical column spatial_outlier appended.
