WebMercator is reported as deprecated EPSG:3785 instead of EPSG:3857 in metadata

[jdenisgiguere]

Current situation

When I reproject a layer into a ZoomLayoutScheme using geotrellis.proj4.WebMercator as CRS, the json file of metadata of the resulting layer will contain this srs definition:

"crs":"+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs "

If I query the AttributeStore metadata for crs.epsgCode it will return: 3785.
EPSG:3785 is a deprecated code for Web Mercator.

In geotrellis.proj4.WebMercator, we explicitly expose epsgCode as 3857.

Expected situation

When looking at metadata.crs.epsgCode of a layer reprojected to geotrellis.proj4.WebMercator , I would expect the value to be 3857.

Hi @jdenisgiguere it is a proj4j bug: locationtech/proj4j#61
It is not a critical issue though.

Thanks for reporting!

Is addressed here: locationtech/proj4j#71
I'll close this issue once we'll upgrade GT up to the fresh proj4j release.
