I use PROJ.4
cs2cs to convert data from a Lambert Conformal Conic to a geodetic coordinate (NAD83) or vice versa. In my application, sometimes I need to convert a lot of data. Because I call
cs2cs with subprocess.Popen() and parse result in python, input/output overhead becomes too big for a large data set.
Is there an faster alternative to cs2cs or a way to make calling
cs2cs in python faster?
