Synthesized Features
•
Up to six (6) different sizes of each graphic (i.e., switch) and its
corresponding labels can be managed and exported from GIS.
These different sizes of graphics and labels are exported to different
specific levels in our OMS map, so they can be controlled and turned on
and off as the user zooms in and out on the OMS map (the user will only
see the appropriate size of the graphic and level at any zoom level).
•
– Each graphic and label size can be managed individually within GIS (have different
placement, orientation, etc.), and are not dependent on the base graphic for its
insertion point.
– Even though there may be six (6) different sized graphics for one device, each
graphic still fully represents that device. If you open a switch at the smallest
representation of a switch, all larger representations of that switch show that it is
open, and be colored appropriately.
– Each of the individual sized graphic (i.e., switch) is still tied to the device and
attribution
– Each of the individual sized labels is still tied to the device and attribution.
– Each label may have different text than it’s larger or smaller version.

Synthesized Features
In this slide you can see 4 different graphics for a single switch, as well as 4 different labels.
Only one label and graphic will be shown at any one time, depending on how far the operator is zoomed in or out, so that the
operator always maintains visibility to both the label and the graphic.
Each of them represent the common device.
Each label and graphic also have a different individual insertion point that is managed within GIS for whitespace to allow the
operators the best view of device and label.

Example of our Usage of Synthesized
Features within OMS for the Operators
4
Initial View
The initial view of switch gear U-8975-S, zoomed in. Note that there are 4 labels for the switch gear. U-8975-S is the
name, and each switch has a label (SW-1, SW-2, SW-3). Note that the colors of the labels match that of the actual
switch it coincides with.
Note that the transformer east of the switchgear has two labels.
5
Zooming Out
Note first that the labels for the switches are changed to 1, 2 (behind arrow), 3 instead of SW-1, SW-2, SW-3. These are a
larger, different set of labels, but are still tied to the device they represent. They are exported from GIS just like you see
here. Notice the placement of the 1, 2 and 3 by U-8975-S. the ‘U-8975’ label is now below the switch gear, and the 1, 2,
and 3 labels are moved differently than the previous slide. The label placement has been manually changed for all 4
labels Since they are unique labels and not just grown, they have different insertion points than the prior slide. Also, note
that the transformer east of the switchgear has a different label than the previous slide. It also is slightly moved from the
previous slide.

Zoom Farther Out
Continuing to zoom out, locals are automatically turned off. Only feeders and feeder devices are shown.
Notice larger graphics and labels at U-8975-S.
Also note that placement of switch graphics and labels for 1, 2 (behind arrow) and 3 are based on different insertion
points than the previous slides.
In this view, the operator sees 3 substations and all their feeder ties, as well as labels.
Since labels and graphic for devices are separate from the previous slide, the insertion points can and have been
changed.

Zoom Farther Yet
Note that even though it may seem a little cluttered, the operator maintains visibility to both devices and labels.
At this view, there are at least 11 substations visible (black and green triangles)

SMUD Clearance Nomenclature
• Like all utilities, SMUD has its unique switching nomenclature
• Map has been designed and optimized to assist Distribution
Operators in clearance writing
• Synthesized features are heavily relied upon by Distribution
Operators during clearance writing at SMUD

SMUD Clearance Nomenclature
Note: In this slide, each transformer has two labels. The upper label has 3 lines, and the lower label is the device name.
Each transformer has two elbows connected to it. The elbows are modeled electrically, and are the devices that are
switched for the clearance.

Description:
As you zoom out from that initial view, notice that a larger
version of the upper label from the previous slide is shown,
but only one line of that label. Notice the actual device name
(lower label from the previous slide) is not there. This is
because only the visible label shown here is used for the
operators in their switch plan (clearance) writing. Elbows are
not grown to keep the map readable - whitespace
management. In this example, if the operator was going to
clear the line between 10-kmp-2 and 9-kmp-2, the switching
would be done at the elbows.
