dtEuclidean: dt Euclidean

In SymbolixAU/spatialdatatable:

Description

Computes the Euclidean distance between two pairs of latitude / longitude coordinates

Usage

dtEuclidean(latFrom, lonFrom, latTo, lonTo)

Arguments

latFrom	latitude from
lonFrom	longitude from
latTo	latitude to
lonTo	longitude to

Value

Euclidean distance

Examples

dt <- data.table(lat1 = seq(-38, -37, by = 0.1),
  lon1 = seq(144, 145, by = 0.1),
  lat2 = seq(-35, -34, by = 0.1),
  lon2 = seq(145, 146, by = 0.1))

dt[, distance := dtEuclidean(lat1, lon1, lat2, lon2)]
