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


   [-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,


                                        mapinfo, xml }.fi

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)
