[Qgis-user] Projections Not Recognized

[Alex Mandel]

Those projections are not identical. NAD83 and NAD83_HARN differ, the
later having a higher precision do to corrections made to NAD83 in the
1990s.

Looking in QGIS I do see StatePlane HARN
EPSG:102348 for North
EPSG:102349 for South

Here's the prj I get making a fresh layer from EPSG:102348
PROJCS["Lambert_Conformal_Conic",GEOGCS["GCS_GRS 1980(IUGG,
1980)",DATUM["D_unknown",SPHEROID["GRS80",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Lambert_Conformal_Conic"],PARAMETER["standard_parallel_1",47.5],PARAMETER["standard_parallel_2",48.73333333333333],PARAMETER["latitude_of_origin",47],PARAMETER["central_meridian",-120.8333333333333],PARAMETER["false_easting",500000],PARAMETER["false_northing",0],UNIT["Meter",1]]

Hmm the standard parllel doesn't match.
So one of these isn't right.
http://epsg.io/102348

Maybe the definition in the EPSG/srs is wrong.

Anyone have a source to confirm what the correct parameters should be.
