validate_coord_list: Test whether decimal GPS coordinates are inside a park unit

In nationalparkservice/IMDQC: NPS Inventory and Monitoring Quality Control Toolkit

Test whether decimal GPS coordinates are inside a park unit

Description

This function can take a list of coordinates and park units as input. In addition to being vectorized, depending on the park borders, it can be a major improvement on validate_coord().

Usage

validate_coord_list(lat, lon, park_units)

Arguments

lat	numeric. An individual or vector of numeric values representing the decimal degree latitude of a coordinate
lon	numeric. An individual or vector of numeric values representing the decimal degree longitude of a coordinate
park_units	String. Or list of strings each containing the four letter park unit designation

Value

logical

Examples

## Not run: 
x <- validate_coord_list(lat = 105.555, long = -47.4332, park_units = "DRTO")

# or a dataframe with many coordinates and potentially many park units:
x <- validate_coord_list(lat = df$decimalLatitutde,
                lon = df$decimalLongitude,
                park_units = df$park_units)
# you can then merge it back in to the original dataframe:
df$test_GPS_coord <- x

## End(Not run)
