array_processing.algorithms.helpers module

array_processing.algorithms.helpers.getrij(latlist, lonlist)

Calculate rij from lat-lon. Returns the projected geographic positions in \(x\)–\(y\) with zero-mean. Typically used for array locations.

Parameters:

• latlist (list) – List of latitude points
• lonlist (list) – List of longitude points

Returns:

numpy.ndarray with the first row corresponding to Cartesian \(x\)-coordinates and the second row corresponding to Cartesian \(y\)-coordinates, in units of km
