The Premise
Most Utility Companies use Geographic
Information Systems (GIS) to operate and
manage their large and complex infrastructure
networks.
According to American Waterworks Association
90% of water agencies now use GIS at least
partially in their daily operation

What is GIS?
A GIS is a computer system capable of capturing,
storing, analyzing, and displaying geographically
referenced information; that is, data identified
according to location. Practitioners also define a
GIS as including the procedures, operating
personnel, and spatial data that go into the system.

GIS Software (General)

Database View


Map View


A GIS is a structured database that can describe
the world spatially.
A GIS is a set of intelligent maps and other views
that show features and feature relationships
spatially
Model View

A GIS is a set of information transformation tools
that derive new datasets from existing datasets.

Geodatabase Versioning

Conceptually similar to CVS




Version is named state of geodatabase
Multiple versions can coexist
A user can connect to any version
Differences between versions can be
merged/reconciled
Controls Group
Versioning Benefits

Could create named versions at useful
savepoints such as the completion of an
experiment, or just prior to or following a
maintenance period.

Tables containing CAD objects, software
configuration info, Optics could all be
versioned consistently.
Controls Group
Spatial Indexes & Operators


Allow efficient queries based on geometric
relationships such as proximity, adjacency, and
overlay.

CAD Files
CAD drawings have limitations:
•
Engineering staff who maintain drawings must be notified to
make changes by installers or Survey & Alignment team.
•
Changes to the as-built drawings are made separately from
changes to software configuration and physics models.
•
The CAD drawings are tiled.
•
The CAD annotation is static.
Controls Group
ArcGIS can Integrate CAD

Option 1 - Use entire file as a layer.
 Option 2 - Decompose the CAD file and
import its contents into geodatabase.



Objects now stored in DB can be extended with
additional attributes.
Can be joined/related to other DB tables.
Can be used to generate new CAD files, not
constrained to tiling, labelling of original.

Schematics

Select a magnet and on-the-fly
generate a schematic of all magnets,
shunts, and shunt-adders in its
circuit.

Select a rack containing Camac crate and click
to generate a schematic showing logical
connectivity of iocs, gpib devices, serial devices,
and cables

Benefits

Highly functional UI without custom programming.
 Complementary to non-spatial database-building
efforts (à la IRMIS).
 Location-awareness fits operational goal of regioncentric rather than system-centric control system.
 Potential to manage controls, engineering, and
model data consistently.

Drawbacks



The software is not free.
The software might be overkill.
There is limited Prior Art to emulate.
Controls Group
Exploratory Project

Use ArcGIS and Geodatabase for
configuration of new Art++ model server



Import data from OptiM, DIMAD, and CAD

Export Up-to-date layout & element properties to
Art++

Importing CAD - Troublesome

Songsheets in arbitrary drawing units.


Songsheets make no use of layers.


Cross-section, plane-view, annotation, and page template
are all intermingled in a single drawing layer,
Elements are all lines, not polygons.


Must open each, define pair of matchpoints to correlate
drawing coordinates to accelerator coordinate system.
Processing is required to merge related lines into a single
geodatabase polygon object.
Annotation is simply written onto page.

Not attached to elements as Xdata

But Exploration Can Proceed

Interface for Model Server to Read GIS



Summary

The ArcGIS software appears to be a capable
framework to consistently manage Engineering,
Controls, and Optics data.

The ability to buy a ready-made interface for
displaying, querying, and analyzing data could
free us to concentrate on data and processes rather
than GUI development.
