Message For Montana there was a FIPS Zone of 4526, now it has changed to 2500. Can somebody shed some light on why that was changed. We are using the 2500 but we are also getting some information from another source that is projected in 4526 ? I'm basically looking for some information on what the differece is and why it is no longer listed in the options under ArcInfo Desktop.

Message Ron,

In workstation ArcInfo (the PROJECT and related commands), there are two ways
to identify a State Plane zone. The keyword, 'ZONE' uses an old BLM set. That's
the 4526 number for Montana. The keyword, 'FIPSZONE' uses a more recent set
that was defined by NOS/NGS (National Ocean Service/National Geodetic Survey).
At the time, this later set was also put into the queue to get approved as a FIPS
standard which is why we used the word, 'FIPSZONE'.

The move to get the values approved as a FIPS standard has since been dropped.
The 'FIPS' (NGS) set is more complete than the older BLM set. For desktop ArcInfo,
we use the newer set exclusively although we can convert the 'ZONE' numbers into
the NGS values.
