In September 1998, Nobel Systems was contracted to by the City of
Glendale, CA to create the database design for the water and reclaimed
water network.
The database design defined the detailed structure and specifications
of the water and reclaimed water GIS layers. The design specifications
were documented in the form of a data dictionary. The data dictionary
contained a description of each layer, the data types used to model
water and reclaimed water facilities, table structures, item (field)
definitions, coding schemes, and other relevant information. The
data dictionary served as the information resource for conversion
vendors, data maintenance staff, programmers, managers and end users
as to what GIS data are available and what format they were in.
The database design effort included:
- ArcInfo coverage definition and topology
This described
the type of features in each coverage.
- Annotations and text attribute tables (TAT)
This described
the fixed annotation display and identified the attributes stored
in the TAT. This also defined text size and position standards for
annotation.
- Symbol Library
This described the different symbols for
all node and point features. It also defined the line types and
symbols for other features such as easements.
Project 2: Water and Reclaimed Water
GIS Data Conversion, Development of GIS Database Maintenance Application,
Development of ESRI MapObjects GIS Viewing Application
In June, 1999, the City of Glendale contracted with Nobel Systems
to convert water and reclaimed water atlas maps and as-built maps
into an ArcInfo database. This conversion enabled the City of Glendale
to improve service and reduce costs. Also included in the project
was the development of GIS software applications (maintenance and
viewing applications), training on GIS and the applications developed
under this contract, and recommendations on the GIS computer hardware
and software requirements. The end result was a fully functioning
GIS system for the City of Glendale’s Water Services Department.
The focus of the City of Glendale GIS Data Conversion
Project consisted of converting all sectionals maps and as-built
drawings pertaining to potable and recycled water distribution systems
into the City of Glendale’s ARC/INFO database. The conversion
process included rectification of all features and interpretation
of attributes depicted on existing sectionals, as-built drawings,
and other source documents. It also included an upgrade of the previous
pilot project data and the complete automation of the new pilot
area data in order to conform to the production database design.
Nobel Systems entered input information from valve and hydrant data
sources and linked valid information to features in the GIS coverage.
Nobel Systems also created applications for database maintenance
and GIS-based data query and analysis. Furthermore, Nobel Systems
also provided training to the City of Glendale’s staff on use
of these applications.
Project 3: Update and Maintenance
After completion of the data conversion project, the City of Glendale
fell behind on maintaining/updating of their data. Nobel Systems
supported the City of Glendale in this effort by providing on-site
staff to finish with their data maintenance activities. This also
included training of the City of Glendale staff to learn how to
use the applications.
