OGC GML download option

[MBennGit]

It is currently not possible to download OGC GML from epsg.io. Has this been changed recently?

Requests to for example to

• https://epsg.io/4326.gml
• https://epsg.io/32632.gml

return

{"error_type": "NOT_FOUND", "message": "Could not find results for given code", "status": "error"}

The functionality to request gml is required for example by python packages such as pyepsg, and thereby cartopy <= 0.19.x (released April 2021), and might still be in use.

Hi @MBennGit

GML dumps are no longer provided by EPSG authority. Their newer dumps are based on WKT.

You may migrate to the new JSON format. It's also a little easier to parse

https://epsg.io/32632.json

I do not know what GML dump means here but their service still returns GML and might be an option

Harvesting GML endpoints isn't ideal since there are about 20k records. Epsg.io uses bulk downloadable datasets instead.

The recommended way is to switch to JSON, there are barely a few applications that still use GML for CRS info.

For information, https://epsg.org/download-dataset.html says about 10.076 dataset

note iii
Download of the full dataset in GML is no longer supported. GML documents for individual entities may be accessed through EPSG Dataset / Text Search.

But there is no bulk downloadable json at apsg.org, so does epsg.io (unfortunate choice for the site name IMHO) create json from WKT?
