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 }

## 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)
