Got another question here. I dont think you can use maxextent to get the required correction to apply since a user may change it. I also notice that the logic used seems to apply to rectilinear projections - it wouldnt be accurate for say conic projections. It seems that accurate way to transform geometry crossing the 180 is unproject to pixel then reproject again but without 180 corrections. -- Phil Scadden, Senior Scientist GNS Science Ltd 764 Cumberland St, Private Bag 1930, Dunedin, New Zealand Ph +64 3 4799663, fax +64 3 477 5232
