It has also been good for understanding what the adjustment meant

In terms of the naming – based on what we are hearing from the parcel people we would suggest a name without a date is better understood and could the name be pronounceable rathehr than just a set of letters

Like GeoRef or BaseRef or BaseGeo of Jersey

Okay – I am grasping at straws here but you have to admit – TIGER worked as a name – we need something that pronounceable since this will be the basis for so much consumer based positioning eventually

Just my opinion, not that of the cad community (NationalCad)

NSRS 2007 (and NSRS 2XXX) appears to be a good naming system.

The datum has not changed, so keep NAD-83.
The pattern used in the past has been to add the date of the readjustment,
I see no reason to change this pattern, unless you want to confuse people
now and in the future. Also, as in previous replies, many states have their
official coordinate systems defined using NAD-83. Changing this would
most likely cause a lot of legislative changes and/or legal problems. I can
envision a circumstance where a surveyor is sued for using a coordinate
system other than NAD-83, even though it actually is the same.

NAD 83 (Adjustment year) seems to be the simplest and conforms to prior naming conventions

Tongue in cheek suggestion - NAD83(Final)

Hello colleagues:
In discussion with a colleague the other day, a reason surfaced for NOT
including the term "NSRS" in the name of the re-adjustment.
The term, NSRS, National Spatial Reference System, is a generic and
important term that is a critical part of NGS' mission. The proposal to
tag one specific adjustment with the same term will cause confusion,
particularly among those who are not all that familiar with our
terminology. Everything in our database is "part of the NSRS" right now,
and the proposed term is intended to identify a sub-set of those stations.
I highly recommend that the NAD83 datum tag for the re-adjustment results
NOT include "NSRS" as part of the name. My preference would be to utilize
the year, as we have done previously, eg, NAD83 (2007). A sentence or two
explaining this new term (adjustment with only CORS for constraints) can
easily and should be added to the "dsdata.txt" file for an explanation of
this new term, as was done for the NAD83 ("HARNyear") term.
Thank you for the opportunity to provide and read others' feedback.

It is important that the National Spatial Reference System Readjustment of NAD83 be unmistakably distinguished from previous adjustments and not follow the previous naming convention. In the past, the date of adjustment tags to the NAD83 datum designation were helpful in distinguishing between coordinate values computed at different times using a piecemeal approach and resulting in inconsistency throughout the network. A simultaneous network adjustment, however, eliminates the inconsistency that necessitated the date of adjustment tags.

Although there is consistency in using the CORS network for control, the CORS network is a dynamic system, based on time-dependent positioning. Thus, it is assumed that the Readjustment of NAD83 will be based upon CORS positions for a particular epoch date. It is also assumed that the CORS positions will, at some point, be updated for a new epoch date. Since this anticipated future update will likely also be simultaneous for the entire network, there is not a need to tag the datum designation with a date of adjustment. It is not the date of adjustment tag but the epoch date that becomes important to distinguish the updated position from superseded values. At present, the datasheets for CORS stations do not have a date of adjustment tag for the datum designation. Rather, the epoch date is noted elsewhere on the datasheet.

In my opinion, NAD 83 (NSRS) would be a sufficient datum designation to distinguish the present and future Readjustments of NAD83, based on the CORS stations, from time-tagged datum designations of the past, based on the HARN stations, as long as the term was explained in the dsdata.txt file and the epoch date was addressed elsewhere on the NGS datasheet in the same manner that it is presently addressed for CORS stations.

When reporting metadata, users should add the epoch date to the datum designation to distinguish between different values for different epoch dates (e.g., NAD 83 (NSRS) epoch 2002.00).

The less confusion the better. We are used to the format of NAD (some date),(adjustment date),(epoch date). Why not continue in with the same fashion?

Ok,

How about a middle road? Namely NAD83 (NSRS07) - epoch date. This is
similar to NAD83 (CORS96) - epoch date. This should accommodate the people
that want a specific year on the tag and the fact that several years of
communication on the "NSRS" tag have been put out there.

I like NAD83(NSRS)

State law wll have to be changed if you take the NAD83 out.

The book I am writing on the global spatial data model (GSDM) is nearing completion. For reasons that will make more sense following publication, my suggestion for the name is NAD83(3D). In reality, with all cards on the table, I believe NAD83(07) is the most expedient name at this time.

I think that NAD83 with a datum year: NAD83 (2007) would be appropriate
for a readjustment name. This will not be the last readjustment. It is
easier to decipher what it means if the year is added. I can get a
question from 1927 datum and know right away why they are not fitting
1983 datum, by the distance they missed the position. I am not saying
that there will be that large of a difference but knowing the year would
help when holding positions fixed in a GPS Project.
