💖 NAME 💖

okay so bestie, welcome to the manual page for Geo::GDAL::FFI::SpatialReference ✨ — it's a spatial reference system in GDAL. Yes, in Perl. Yes, it's a .3pm page from the User Contributed Perl Documentation. Yes, you're gonna slay every projection you touch. 🎀

🌸 SYNOPSIS 🌸

okay so… there's literally nothing here 😭 the SYNOPSIS section is empty in the original. Not a single line. It's giving mysterious 💅. Scroll down to METHODS for the actual tea.

🦋 DESCRIPTION 🦋

It's a spatial reference system. That's the whole vibe. Everything you can actually do with it lives in METHODS below ⬇️

👑 METHODS 👑

✨ new ✨

Create a brand new SpatialReference object. Fresh out the box, main character energy 🫶

my $sr = Geo::GDAL::FFI::SpatialReference->new('WKT here...');

So here's the deal: if you hand it only one argument, that argument gets read as the well known text (WKT) that belongs to the spatial reference system (SRS). That's it, that's the whole thing 💅

my $sr = Geo::GDAL::FFI::SpatialReference->new(EPSG => 3067);

But if you give it more than one argument? Then the first argument is treated as a format, and everything after that is treated as arguments handed off to that format. Iconic, honestly.

So the formats GDAL knows about — at least at the time this was written, no cap — are:

  • EPSG
  • EPSGA
  • Wkt
  • Proj4
  • ESRI
  • PCI
  • USGS
  • XML
  • Dict
  • Panorama
  • Ozi
  • MICoordSys
  • ERM
  • Url

✨ Export ✨

$sr->Export($format, @args);

This one exports your SpatialReference object out into some format — like, taking it out of the house for the night 🌈

The formats GDAL knows about (again, as of the time this was written) are:

  • Wkt
  • PrettyWkt
  • Proj4
  • PCI
  • USGS
  • XML
  • Panorama
  • MICoordSys
  • ERM

✨ Set ✨

$sr->Set($proj, @args);

This sets projection parameters on a SpatialReference object. Basically you're telling it who it is. Glow up moment ✨

The projection parameters GDAL knows about — at the time of this writing, bestie, don't come for me — are:

  • Axes
  • ACEA
  • AE
  • Bonne
  • CEA
  • CS
  • EC
  • Eckert
  • EckertIV
  • EckertVI
  • Equirectangular
  • Equirectangular2
  • GS
  • GH
  • IGH
  • GEOS
  • GaussSchreiberTMercator
  • Gnomonic
  • HOM
  • HOMAC
  • HOM2PNO
  • IWMPolyconic
  • Krovak
  • LAEA
  • LCC
  • LCC1SP
  • LCCB
  • MC
  • Mercator
  • Mercator2SP
  • Mollweide
  • NZMG
  • OS
  • Orthographic
  • Polyconic
  • PS
  • Robinson
  • Sinusoidal
  • Stereographic
  • SOC
  • TM
  • TMVariant
  • TMG
  • TMSO
