💅 gdalsrsinfo(1) — the GDAL era ✨

okay so bestie, this is the manual page for gdalsrsinfo, straight out of the GDAL collection. it's a tiny little tool that spills the tea on any SRS you throw at it, and honestly? it ate. let's get into it 🫶

🌸 NAME 🌸

gdalsrsinfo — lists info about a given SRS in a number of formats (WKT, PROJ.4, etc.). that's it, that's the whole job, and it does it gorgeously 💅

✨ SYNOPSIS ✨

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

like, that's the whole vibe. short king 🎀

🦋 DESCRIPTION 🦋

the gdalsrsinfo utility reports information about a given SRS from one of the following, and yes you have options bestie:

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) ⭐

so flexible. so iconic. main character energy fr fr 🌈

🧚 the flags 🧚

--single-line — prints the WKT on a single line. one line. no scrolling, no drama, lowkey a lifesaver 😌
-V — validate the SRS. it's giving vibe check for your coordinate system ✅
-e — search for EPSG number(s) corresponding to the SRS. detective mode activated 🔍
-o <out_type> — picks your output type. here's the whole menu, no cap:
- 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_2018
- wkt2: latest WKT2 version supported, currently wkt2_2018
- wkt2_2015: OGC WKT2:2015
- wkt2_2018: OGC WKT2:2018
- mapinfo: Mapinfo style CoordSys format
- xml: XML format (GML based)

literally so many flavors, pick your fighter 🍓

<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). either way, she's serving 🫶

🔥 EXAMPLE 🔥

okay this is the part where she really shows off. watch 👑

$ gdalsrsinfo EPSG:4326

PROJ.4 : +proj=longlat +datum=WGS84 +no_defs

OGC WKT :
GEOGCS["WGS 84",
    DATUM["WGS_1984",
        SPHEROID["WGS 84",6378137,298.257223563,
            AUTHORITY["EPSG","7030"]],
        AUTHORITY["EPSG","6326"]],
    PRIMEM["Greenwich",0,
        AUTHORITY["EPSG","8901"]],
    UNIT["degree",0.0174532925199433,
        AUTHORITY["EPSG","9122"]],
    AUTHORITY["EPSG","4326"]]

and then she can pull the proj4 straight out of a .prj file too, no biggie:

$ gdalsrsinfo -o proj4 osr/data/lcc_esri.prj
'+proj=lcc +lat_1=34.33333333333334 +lat_2=36.16666666666666 +lat_0=33.75 +lon_0=-79 +x_0=609601.22 +y_0=0 +datum=NAD83 +units=m +no_defs '
\endverbatim

yeah that \endverbatim is just... there. we don't ask questions, we just vibe 💀

rasters work too, bestie — a whole GeoTIFF, no problem:

$ gdalsrsinfo -o proj4 landsat.tif
PROJ.4 : '+proj=utm +zone=19 +south +datum=WGS84 +units=m +no_defs '

and now the big one — full WKT2 for EPSG:32722, look at all those parameters 😭✨

$ gdalsrsinfo  -o wkt "EPSG:32722"

        BBOX[-80,-54,0,-48]],
    ID["EPSG",32722]]

and if you're feeling extra and go -o wkt_all on EPSG:4322, she serves the ENTIRE buffet. first up, OGC WKT 1:

$ gdalsrsinfo -o wkt_all "EPSG:4322"
OGC WKT 1:

    DATUM["World_Geodetic_System_1972",

    AXIS["Latitude",NORTH],

    AUTHORITY["EPSG","4322"]]

then OGC WKT2:2015 — the way that BOUNDCRS wraps everything, obsessed 🦋

then OGC WKT2:2018, which is basically the same but with GEOGCRS and USAGE blocks doing their little glow-up:

        ID["EPSG",1237]]]

then the simplified WKT 1, because sometimes you just want the short version 💅

OGC WKT 1 (simple) :
GEOGCS["WGS 72",
    DATUM["World_Geodetic_System_1972",
        SPHEROID["WGS 72",6378135,298.26],
        TOWGS84[0,0,4.5,0,0,0.554,0.2263]],
    PRIMEM["Greenwich",0],
    UNIT["degree",0.0174532925199433]]

and WKT 1 with no CT params — even shorter, still valid:

OGC WKT 1 (no CT) :
GEOGCS["WGS 72",
    DATUM["World_Geodetic_System_1972",
        SPHEROID["WGS 72",6378135,298.26]],
    PRIMEM["Greenwich",0],
    UNIT["degree",0.0174532925199433]]

and finally the ESRI WKT, for when your software speaks Esri 🧚

ESRI WKT :
GEOGCS["GCS_WGS_1972",
    DATUM["D_WGS_1972",
        SPHEROID["WGS_1972",6378135.0,298.26]],
    PRIMEM["Greenwich",0.0],
    UNIT["Degree",0.0174532925199433]]

see? all the formats. all of them. she contains multitudes ✨
