NAME

       gdalsrsinfo - gdalsrsinfo lists info about a given SRS in number of formats (WKT, PROJ.4, etc.)

SYNOPSIS

       Usage: gdalsrsinfo [options] srs_def

       srs_def may be the filename of a dataset supported by GDAL/OGR from which to extract SRS information
       OR any of the usual GDAL/OGR forms (complete WKT, PROJ.4, EPSG:n or a file containing the SRS)

       Options:
	  [--help-general] [-h]  Show help and exit
	  [-p]			 Pretty-print where applicable (e.g. WKT)
	  [-V]			 Validate SRS
	  [-o out_type] 	 Output type { default, all, wkt_all, proj4,
					       wkt, wkt_simple, wkt_noct, wkt_esri,
					       mapinfo, xml }.fi

DESCRIPTION

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

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

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

       Output types:

       o default   proj4 and wkt (default option)

       o all   all options available

       o wkt_all   all wkt options available

       o proj4	 PROJ.4 string

       o wkt   OGC WKT format (full)

       o wkt_simple   OGC WKT (simplified)

       o wkt_noct   OGC WKT (without OGC CT params)

       o wkt_esri   ESRI WKT format

       o mapinfo   Mapinfo style CoordSys format

       o xml   XML format (GML based)
