[SOLVED] What spatial SRID is this? (trying to convert a .shp file to WSG84)

What spatial SRID is this? (trying to convert a .shp file to WSG84)

I'm trying to import some Shapefile mapping data into Sql2008. Before I do that, I need to convert it to WGS84 / SRID 4326, because all my existing data is in this format.

This is the source file info:

GEOGCS["GCS_GDA_1994",DATUM["D_GDA_1994",
    SPHEROID["GRS_1980",6378137,298.257222101]],
    PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]

I've tried googling for this and haven't had too much luck. Secondly, I've tried to check the spatial_reference_systems table and I can't see it in there.

eg. SELECT * from sys.spatial_reference_systems

So, can anyone help me? I can't covert it to SRID 4326 if i don't know it's current SRID.

UPDATE 1

I found this page which explains the tech specs of GDA 1994 .. but doesn't hint at any SRID number... ???

UPDATE 2

This search result page also has some interesting results. From here, if you click on the SR-ORG:6643: Australia Albers Equal Area Conic link, it explains that datum .. and it's pretty much identical to the one I'm searching for. This means the SRID is 6643.

So is that the answer?

Solution

Using FME as my reference, this (GDA94) maps to EPSG:4283, which means that you need to use SRID 4283 (assuming that you're using EPSG-compliant SRID values)
