gdalsrsinfo - Man Page

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)
