Details
Norwegian landings data often list landing sites by identifiers for municipalities (kommunenummer). This resource can be used to infer location code that are associated with polygons or coordinates, such as UN/LOCODES.
The Norwegian municipalities have been subject to revision, and other resources may have to be obtained to completely handle data from other years.
Examples
# map kommune to locodes
data(kommuner2022)
data(portcodes2020)
nocodes <- portcodes2020[portcodes2020$Country=="NO" & !is.na(portcodes2020$latitude),]
locodemap <- RstoxFDA::appendAreaCode(nocodes, kommuner2022,
colName="kommune",
latName = "latitude",
lonName = "longitude")[,c("kommune", "Location")]
# Note that kommune does not uniquely identify locode:
locodemap[locodemap$kommune==4601,]
