GDA2020 in Proj4

Hi,

I’m trying to use Proj4Projection.GetEpsgParametersString(srid) to get Proj4 string for EPSG ID 7855 which is in the GDA2020 projection system, but the function returns an empty string.

I am guessing these new CRS have not yet been implemented in the proj4 libraries. Any idea when that will be? The format was introduced in 2016, so should be in there by now.

Thanks,
Damian

Thanks Damian,
You may need find the proj4 for GDA2020. I found something here

We can not find the GDA2020 proj4 string. It may need adjust the GDA94 proj.4 string a little base on the specification of GDA2020 .

Thanks

Frank
