Get AGDD Point Value

Source: R/npn_geoserver.R

This function is for requesting AGDD point values. Because the NPN has a separate data service that can provide AGDD values which is more accurate than Geoserver this function is ideal when requested AGDD point values.

npn_get_agdd_point_data(layer, lat, long, date, store_data = TRUE)

Arguments

layer

The name of the queried layer.

lat

The latitude of the queried point.

long

The longitude of the queried point.

date

The queried date.

store_data

Boolean value. If set TRUE then the value retrieved will be stored in a global variable named point_values for later use.

Value

Returns a numeric value of the AGDD value at the specified lat/long/date. If no value can be retrieved, then -9999 is returned.

Details

As this function only works for AGDD point values, if it's necessary to retrieve point values for other layers please try the npn_get_point_data() function.
