Assign longitude and latitude points to zonal centroid

Assign longitude and latitude points to zonal centroid

Usage

lonlat_to_centroid(dat, project, lon, lat, spat, zone)

Arguments

dat

Main data frame over which to apply function. Table in FishSET database should contain the string `MainDataTable`.

project

Project name.

lon

String, variable name containing longitude.

lat

String, variable name containing latitude.

spat

Spatial data table containing regulatory zones. This can be a "spatial feature" or sf object.

zone

String, column name contain the assigned zone. Must be the same for both the spatial data table and MainDataTable.

Details

This is one of the FishSET confidentiality functions. It replaces the selected longitude and latitude columns with the zonal centroid derived from a spatial data table.

Examples

if (FALSE) {
lonlat_to_centroid(pollockMainDataTable, "pollock", spatdat, 
                  lon = "LonLat_START_LON", lat = "LonLat_START_LAT",
                  zone = "NMFS_AREA")
}
