GDALSRSINFO(1)

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

SYNOPSIS

    Usage: gdalsrsinfo [--help] [--help-general]
                       [--single-line] [-V] [-e][-o <out_type>] <srs_def>

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)

--help
    Show this help message and exit

--help-general
    Gives a brief usage message for the generic GDAL commandline options and exit.

--single-line
    Print WKT on single line

-V  Validate SRS

-e  Search for EPSG number(s) corresponding to SRS

-o <out_type>
    Output types:

•   default: proj4 and wkt (default option)

•   all: all options available

•   wkt_all: all wkt options available

•   PROJJSON: PROJJSON string (GDAL >= 3.1 and PROJ >= 6.2)

•   proj4: PROJ.4 string

•   wkt1: OGC WKT format (full)

•   wkt_simple: OGC WKT 1 (simplified)

•   wkt_noct: OGC WKT 1 (without OGC CT params)

•   wkt_esri: ESRI WKT format

•   wkt: Latest WKT version supported, currently wkt2_2019

•   wkt2: Latest WKT2 version supported, currently wkt2_2019

•   wkt2_2015: OGC WKT2:2015

•   wkt2_2019: OGC WKT2:2019 (for GDAL < 3.6, use wkt2_2018)

•   mapinfo: Mapinfo style CoordSys format

•   xml: XML format (GML based)

<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)
