Validate latitudes and longitudes

Description

Check each latitude and longitude value to see if they are NA or outside expected numeric ranges (based on approx ranges of lat lon seen among block internal points dataset) lat must be between 17.5 and 71.5, and lon must be ( between -180 and -64) OR (between 172 and 180)

Usage

latlon_is.valid(lon, lat, quiet = TRUE)

Arguments

lon	numeric vector of longitudes in decimal degrees, same length
lat	vector of latitudes in decimal degrees
quiet	optional logical, if TRUE, show list of bad values in console

Value

logical vector, one element per lat lon pair (location)
