Utility data repositories are changing

Utility Data Repositories are Changing

  • 1980s and before

    • Used to be collection of paper maps maintained and controlled by individual utility owners

  • 1990s

    • Digital CADD files and paper maps

  • Now

    • All of the above, plus GIS

    • Who is in control of data?

    • Who keeps data current?


Cadd gis are merging

CADD & GIS are Merging

  • CADD is Graphical

  • GIS is Database + Graphics

  • GIS has much more available data, and data can be organized and searched

  • Both CADD & GIS are going 3-D

  • GIS will serve many more masters than CAD, and therein lies the challenge


How close is gis to taking over the utility engineering field

How Close is GIS to Taking over the Utility Engineering Field?

  • FAA already requiring all airports to do their layout plans for design in GIS rather than CAD

  • SHRPII R-01A Research project is about developing standards and protocols for GPS/GIS to build Utility Data Repositories for state DOTs


Challenges of utility data repositories

Utility Management System Architecture

A Geographic Information System (GIS) assembles information from several sources, including ground surveys, existing maps, aerial photos, and satellite imagery. In a GIS, specific information about a place, such as the locations of utility lines, roads, streams, and buildings, is layered over a set of geodetic data.

Because a GIS stores data digitally, information can be quickly and economically updated, easily reproduced, and made widely available. In fact, because of its power and speed, GIS technology is doing most of the cartographic (mapmaking) work that, in the past, was laboriously done by hand on paper charts and maps.


Geographic information systems

Geographic Information Systems

  • Challenges

    • system architecture for creating robust legacy data inventory and data integration

      • GIS, Geodesy, National Standards, State Statutes

    • management buy-in and funding

    • initial data collection

    • data maintenance


Challenges of utility data repositories

Everybody needs to understand lingo and basics.

Good idea to run everyone through basics.


Challenges of utility data repositories

Need multi-discipline team to manage initiative – don’t just turn it over to GIS nerds.

Leader needs to have multi-discipline background to understand and guide effort.

GIS, PLS, and engineering communities have in general not yet fully meshed. Throw on top of that, all of them lack an understanding of utilities.


Challenges of utility data repositories

Managing three data types:

  • attribute (what it is)

  • coordinate (where it is)

  • metadata (data about the data)

Need to be able to access, update, query, and retrieve data readily, and push it back into variety of CADD platforms, tied and projected to desired project coordinate system.


Challenges of utility data repositories

What defines robust, legacy data?

Need essential attribute data fields

e.g., size, capacity, material, ownership, conduit, quality levels, coordinates

Need essential meta-data

e.g., data source, acquisition campaign, survey control and projection, engineer-of-record

Need coordinate data tied to national datum

Comply with Federal and international data standards (FGDC and ISO)


Challenges of utility data repositories

Positional accuracy is paramount for utilities.

Ensure system development includes individuals who understand the science of geodesy. Otherwise data usage will be limited to inventory type applications.


Challenges of utility data repositories

Geodesy - the science of measuring and monitoring the size and shape of the Earth and the location of points on its surface. NOAA's National Geodetic Survey (NGS) is responsible for the development and maintenance of a national geodetic data system that is used for navigation, communication systems, and mapping and charting.


Challenges of utility data repositories

Positional data and accuracy is the foundation for a GIS based utility data management system.

National Spatial Reference System

Datum to securely support other spatial information


Challenges of utility data repositories

NSRS Horizontal Datum

In 1927 the U.S. Coast and Geodetic Survey, the predecessor of the National Geodetic Survey, "connected" all of the existing horizontal monuments together and created the North American Datum of 1927 (NAD 27). This datum was used extensively during the next 60 years as the primary reference for horizontal positioning. In 1983, NAD 27 was adjusted to remove inaccuracies and to correct distortions. The new datum, called NAD 83, is the most commonly used horizontal positioning datum today in the United States.


Challenges of utility data repositories

NSRS Vertical Datum

In 1929, the National Geodetic Survey (NGS) compiled all of the existing vertical benchmarks and created the National Geodetic Vertical Datum of 1929 (NGVD 29). Since then, movements of the Earth's crust have changed the elevations of many benchmarks. In 1988, NGVD 29 was adjusted to remove inaccuracies and to correct distortions. The new datum, called the North American Vertical Datum of 1988 (NAVD 88), is the most commonly used vertical datum in the United States today.


Challenges of utility data repositories

Positional data and accuracy is the foundation for a GIS based utility data management system.


Challenges of utility data repositories

Taking it to Next Level - CORS and GIS

The Continuously Operating Reference Stations (CORS) system is a network that continually corrects GPS signals, and provides these corrections to GPS users over the Internet.

Relatively simple to tie all observations to the NSRS


Challenges of utility data repositories

National Committees and Centers

  • Federal Geographic Data Committee - representatives from

  • Dept.’s of Ag, Commerce, Defense, Energy, Housing and

  • Urban Development, Interior, State, Transportation, EPA,

  • FEMA, Library of Congress, NASA, National Archives, and

  • Tennessee Valley Authority.

  • CADD/GIS Technology Center for Facilities, Infrastructure,

  • and Environment, located at the U.S. Army Engineer

  • Research and Development Center’s Information

  • Technology Laboratory in Vicksburg, MS - a consortium

  • for joint development of CADD and GIS standards by the

  • Army Corps of Engineers, Army, Air Force, Navy, Marines,

  • and other federal, state, local government agencies.


Challenges of utility data repositories

National GIS Data Standards

  • Spatial Data Standard for Facilities, Infrastructures, and Environment (SDSFIE)

    • CADD/GIS Technology Center, Information Technology Laboratory (ITL), U.S. Army Engineer Waterways Experiment Station (WES) Vicksburg, MS, a complex of five laboratories of the U. S. Army Engineer Research and Development Center (ERDC). The CADD/GIS Technology Center was chartered in 1992 to promote the use of CADD and GIS technologies for life-cycle facilities management within the Army, U.S. Army Corps of Engineers, Navy, and Air Force.

ESRI ArcGIS Survey Analyst (Oct ‘02) developed under contract with US Army Corps of Engineers as a result.


Challenges of utility data repositories

Need business process

Capture data from permitting, construction, and SUE activities

Need digital data standards, special provisions, and templates for data submittals

Need repository


Challenges of utility data repositories

Be mindful of state statutes regulating publication of mapped fixed features of engineering.“Model Law” for management of survey data in a GIS


Challenges of utility data repositories

Utility Management System Buy-In

  • Need management to support need.

  • Need cost / benefit analysis and business process.

  • Need funding.

    • Consider banding with regional metropolitan entities, cities, counties, transit authorities, and other state agencies with identical needs - support a single system with pooled permit fees.

  • Need to educate continuously on why this is not a trivial exercise.

  • May need legislative changes and utility lobby support.
