After some difficulty entering coordinates, I have succeeded in creating a GeoTIFF maps. Using degrees and minutes (eg S41°21.334' E174°54.746') produced grotesque (skewed and reversed) maps. Using decimal degrees (eg S41.3556 E174.9127) produced near perfect GeoTIFF maps. May be this is a conflict between North/West v South/East bearings when using degrees and minutes? The only imperfection is that the Lon/Lat grid on the map is not verticle/horizontal, the map is rotated counter-clockwise 1.6degrees. Is there a way to correct this? Below is a copy of the saved reference file.
