# gdalsrsinfo

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

## Synopsis

    Usage: gdalsrsinfo [--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)

--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)
