   [--help-general] [-h]  Show help and exit
   [-p]                   Pretty-print where applicable (e.g. WKT)
   [-V]                   Validate SRS
   [-e]                   Search for EPSG number(s) corresponding to SRS
   [-o out_type]          Output type { default, all, wkt_all, proj4,
                                        wkt, wkt_simple, wkt_noct, wkt_esri,

DESCRIPTION

The gdalsrsinfo utility reports information about a given SRS from one of the following:

•   The filename of a dataset supported by GDAL/OGR which contains SRS information

•   Any of the usual GDAL/OGR forms (complete WKT, PROJ.4, EPSG:n or a file containing the 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)
