00:00:28.570 --> 00:00:32.740
When a layer is activated, you
will see a tip here about how to

4df0fb7c-fcf0-468b-a5d7-7b195b1bda02-0
00:00:44.130 --> 00:00:46.982
We're not going to go through
each layer, but we will hit the

4df0fb7c-fcf0-468b-a5d7-7b195b1bda02-1
00:00:46.982 --> 00:00:49.559

00:01:10.160 --> 00:01:13.834
This is the same window that
would have popped up had you

00:02:00.528 --> 00:02:05.280
example, I'll use the water tab
and drop down to salinity.

f0b5593a-ce59-4200-8322-516e23f4c719-0
00:02:06.140 --> 00:02:09.957

00:02:19.345 --> 00:02:22.346
data, you would use the data
feature which is covered in a

aefa4f6c-3857-4b74-963b-9d3ba6a25f9e-3
00:02:22.346 --> 00:02:23.110

00:02:38.246 --> 00:02:41.865
Now we'll click out of the
expanded chart and scroll back

c492e2b9-aff4-4a29-a86f-b2a1a42fcf21-4
00:02:41.865 --> 00:02:45.485

00:02:58.790 --> 00:03:01.540
Now we'll X out of the site
level information window so I

12a3aebc-66ec-4678-9fbf-56a53331dd2b-1
00:03:01.540 --> 00:03:04.244

00:05:58.670 --> 00:06:01.999
If you wanted to view this layer
in conjunction with another

1e05a598-9ffc-43ba-9db9-d3c6218a3529-1
00:06:01.999 --> 00:06:05.110
layer, you can use this slide
bar to change the opacity.

00:06:05.970 --> 00:06:09.200
I'm going to deselect the land
water layer.

00:06:09.960 --> 00:06:11.300
Close up the toggle menu.

00:06:11.990 --> 00:06:15.910
The rest of these checkable
layers function similarly.

00:06:16.580 --> 00:06:19.488
Except for the elevation survey
layer, which you need to be

7f3cfb96-cd9c-493c-8901-7cfa6c3063ea-1
00:06:19.488 --> 00:06:22.446
zoomed in to use, but it tells
you that if you try to use it

7f3cfb96-cd9c-493c-8901-7cfa6c3063ea-2
00:06:22.446 --> 00:06:23.610
without being zoomed in.

00:06:24.730 --> 00:06:28.120
And then I'll mention the base
layers menu.

00:06:28.900 --> 00:06:30.210
Where you can.

00:06:31.180 --> 00:06:32.680
Change the background map.
