Aloha, my name is Casey Rita with the U.S.
geological survey in Honolulu, Hawaii.

The intent of this primer is to show how to
extend ratings and how to apply reading dates


This will also allow us to demonstrate such
tools as cloning ratings and rating overlays.

First we need to get some data to work with,
normally we would retrieve from database but

for this tutorial we will use from file and
use the file that's already been created.

To view the data click read data, if we had
pulled the data from the database all the

ratings associated with this site would be
listed those outside the parameters we chose

would be listed in gray and those within the
parameters would be given in white.

Lastly you will notice in the overview pane
that if we select the rating period, the measurements

associated with that period will identify

We need to extend this rating up to these
new measurements, in the real world we would

have some survey data or other info to help
guide us but for this tutorial were just going

to use the measurements we have.

As you can see rating 6 is approved and therefore
is not able to be edited in any way, so we

have to make a new rating based on rating
6 so that we can edit it to include these

new measurements at the higher end.

There's 2 ways to clone a rating in GRSAT,
you can use the set up drop-down menu and

clone rating or you can use this bad button
right here.

First we need to give the new rating a unique
rating number since it's just a straight line

extension we'll call it 6.1 instead of 7.0.

The remarks field is a good place to keep
important information about this rating, the

tutorial will keep it fun.

In our new rating we can choose to include
measurement settings, offsets, and selected

shifts associated with rating 6.0.

Remember when you're including the shifts
you have to select them one by one, to finish

cloning our rating click okay.

There we go now we want to overlay the original
rating 6.0 so that we can refer to it while

extending rating 6.1, there's 2 ways to do
this with the drop-down menu or the button,

both get you to the same menu.

We want to uncheck overlay in the shifted
curve that way we just referenced the base

curve for 6.0.

You can change the color of the line that
gets plotted into anything you want, you can

choose more colors are one of the standards,
let's go with this rocking blue.

You can also change the line type to pretty
much anything you want but let's leave it

at micro solid now let's overlay the rating
and use it shows up right there.

It goes right over rating 6.0 because right
now we haven't changed anything with the rating


Now that we overlay the rating we get 2 more
choices right here to choose from, we can

change the properties of we don't like the
colors or if want to make a dotted line or

we can simply remove it altogether, since
we just did it for purpose we don't want to

remove it.

Keep in mind the drop-down menu is the same
choices as well.

Now it's time to extend our rating list go
to the rating zoom and you'll see these choices

down here for editing your current rating
that you got up now which is 6.1.

We want to extend so will choose the extend
rating line tool.

You'll notice we have a new rating point now,
when you try and move it you'll see it only

goes in a straight line because it is just
that a straight line, a straight line extension


You can confirm this by looking at the slope
in the rating table and see that the slope

will remain constant no matter where you move
it or how far you move it, you can also note

that when you look in the linear zoom window,
rating zoom to the straight line extension

appears to have a slight curve to it but as
we see on the slope it does not.

You can see that while this too is active
the rating point is reversed colors from the

other points as soon as you click off of this
tool it becomes rating point just like the

others and can be edited.

See it change, if we zoom in you can see a
straight line extension is not really what

we want here, you can also see this in the
shift diagram as these top measurements just

aren't plotting.

It appears as though the upper end of this
rating is breaking into an over bank and the

control is different in this area of the rating.

We may need a second offset, so let's go to
the offset manager if we select a second offset

we need to give it a break point where we
want the second offset to start kicking in,

so let's go up to the part of the rating that
were working on now we can start to adjust

the offset.

As you can see those upper measurements in
the shift diagram start moving towards the

0 shift line, when we get to an offset of
about 8 the measurements start to line up

pretty well so let's view it.

We'll select offset 2 because that's what
were working with an view is so we can see

it, is zoom in a little bit so now we've extended
our rating the measurements at the upper end

plot we have a second offset were still on
rating 6.1 now we need to give it a start

date that way we can put it into action first
let's go to the time series G tab at the bottom

and you see this comes up.

Let's check out what kind of tools we have
in the time series view tab, we can zoom in,

we can zoom in, we can zoom in or we can zoom
out, we can zoom back in, we can grab this

hand and we can pan across so that we can
see different points on the zoomed in curve

or we can go back to where we were.

As you can see the zoom in, zoom out and the
pan buttons allow us to manipulate the view

to help us out to accomplish our goal.

So let's get to her current period of 2004,
2005 that we're actually working with here.

There we go that's better also take notice
of the bars we have at the bottom here we

have the rating date bar that shows the rating
periods, the shift bar shows the shift periods

and the aging bar shows the overall data aging.

The color codes match Hydra red for working,
blue for approved, the color of the shift

bar is different though and that will get
covered in the shifts topic you can also use

his size tool to change the size of the graph
to whatever fits your needs best.

There's also the show high curves tool when
you click it, it shows you things you can

put in and take off if you don't want the
shifts there, they're gone, you want the shifts

back there they are, you want to get rid of
the rating is shift period, they gone, you

want them back where they are.

Since were not really blaming this to rating
on a change in control we can easily just

started at the beginning of our current working
period so to show some GRSATs awesome tools

let's everyone is started during the event
May 2004.

Let's go to the rating period manager, we're
going to select our new rating by double-clicking

it, we are going to give it a rating period
and were going to give it a start date.

Let's say May 1, 2004, we don't want to give
it an end date because he we want to start

this new rating, we don't want to started
and ended at the same time, that's click apply.

As you can see rating 6 ended one second before
this new rating starts therefore rating 6

is over and rating 6.1 is an action, so let's
select rating 6.1, we'll use this tool highlight

in TS pane, TS, time series, get it, click
that button and it will show you where it

takes effect.

See it highlight the period that we're using
6.1 the start date it's occurring because

it hasn't been turned off.

Now let's see how he is the graph down here
to fine-tune our date for the starting date

and ending date of our other ratings.

It will come down to time series view and
select the adjust date button.

Now you just grab this rating 6.1 and we can
scoot it over but it won't let us go back

because we can't overlap rating so let's just
scoot it forward a little bit, um, that looks


Oh now we got a gap in our ratings if we zoom
in down here on the rating tab you'll be able

to see the gap, see that white no rating there,
you can also see it up here in yellow, don't

get scared, don't be afraid, this is a really
easy fix.

We can come back down to our rating bar now
select rating 6.0, grab the black line and

scoot it over no more rating gap, so that
works well easy enough but let's see how there's

other ways to do that.

Up in the rating period manager there's other
tools and different ways to go about exactly

what we did down here.

We can use these tools at the bottom, if we
get rating 6.1 and we put the start date up

we get that same gap, we can bring it back,
the gap goes away, but let's say we really

wanted to started here.

We can go to 6 and do the same thing just
adjusts the end time, the gap goes away, gaps

back, gap goes away.

If adjusting the rating times down here by
15 minutes isn't good enough for you and we

can adjust that too, let's keep it to the
15 minute punches though.

If none of those work for you, you can select
your rating click the properties button and

adjust your dates that way or double-click
on the rating, the same menu comes up as the

properties button.

It's important to note though you can only
change rating dates for ratings that are in

the working, if they are approved are ready
you'll see they are grayed out and there's

nothing you can do about it.

Also in the rating period manager if you don't
like the rating you can delete it but why

would we do that, we just worked so hard at
getting this thing to plot at the upper end

and lastly if we haven't found enough ways
to fill in rating gaps this grade tool can

help too but we have to first give ourselves
a rating gap.

There we got our gap, tool comes in, click
on the rating above the gap and we can insert.

But let's say we have 6.1 starting exactly
when we want to, just like every other computer

program make sure you save before you quit,
after you save and quit the only thing you

would have to do is go back into [inaudible]
it is at this new rating 6.1 to approve, for

now GRSAT still can't change the data aging.

Hopefully everything we went over wasn't too
overwhelming and was simple to follow and

believe me if I can do it you can do it too,
Casey Rita, out.
