Missing EPSG codes for California NAD83 NSRS2007

The window for command MAPCSASSIGN is missing all EPSG codes for California for reference model

NAD83(NSRS2007).

 

There should be 6 EPSG codes for California state plane zones 1-6 in meter units, EPSG codes 3489, 3491, 3493, 3495, 3497, and 3499.

 

There should be 6 EPSG codes for California state plane zones 1-6 in Feet US units, EPSG codes 3490, 3492, 3494, 3496, 3498 and 3500.

 

There should also be EPSG code for California/Teale Albers Equal Area in Meters units EPSG code 3488 for statewide maps as mentioned in a previous post today.

 

AutoCad Civil 3D 2012 and Map 3D do not have any projections referenced to NAD83(NSRS2007).

The NAD83(NSRS2007) reference model was defined in 2005 and needs to be added.

NAD83(NSRS2007) is the current model described by National Geodetic Survey (NSG).

 

Why is this reference model not yet a part of Civil 3D 2012 or Map 3D 2012 ?

 

Please have someone from Autodesk contact me.

These codes are not implemented in Map yet. The issue you described is already reported to the development. Not sure where these will be added to the list of available coordinate systems. As a workaround you may need to add your custom coordinate systems. Instructions should be in help.

 

It would also be a good idea to take a look at these two links:

I've been curious about this myself, but I don't see why another "zone" is necessary. In my mind the datum is NAD83 on a state place projection. The latestest iteration of the datum is NSRS2007, but still on the same projection. I have never understood what the difference between NAD83 CSP, Zone V and HARN (HPGN) CSP, Zone V is. If you have a drawing in one and another in the other, will you see a shift in xref or querry functions?

After contacting NGS, I have been informed that NGS transformation parameters have not yet been established for NAD83(NSRS2007).  Therefore AutoCad cannot create the models.

 

I respectfully withdraw my discussion post until the time NGS creates the transformation parameters.

Here's something I came across during my searches related to a transformation of data to NAD83(2007).
