Has anyone come across a free web service / REST API to transform coordinates?
I'm particularly interested in transforming from WGS84 to: New Zealand Geodetic Datum 2000 (NZGD2000 / NZTM) and New Zealand Geodetic Datum 1949 (NZGD1949 / NZMG). Would be a bonus if I could also get the grid version of coordinates as well.
Apologies if I'm slightly out with my terminology - I'm still a little green to GIS.
Thanks in advance for any advice, Gavin
