SRS)

Output types:

· default proj4 and wkt (default option)

· all all options available

· wkt_all all wkt options available

· proj4 PROJ.4 string

· wkt OGC WKT format (full)

· wkt_simple OGC WKT (simplified)

· wkt_noct OGC WKT (without OGC CT params)

· wkt_esri ESRI WKT format

· mapinfo Mapinfo style CoordSys format

· xml XML format (GML based)
