Daily Procedure

• Obtain as-built or drawings of area to be
  surveyed from office.
• Head to a known survey control point to
  collaborate coordinates
• Move to area of work to start collecting data
• At the end of the week, download data into GIS
  software

Equipment Used
This type of GPS unit uses two parts, a receiver
and a data collector
8
Technological Process

• The receiver calculates coordinates using
  satellites
• The data collector averages and stores those
  points
• Downloading into the system allows us to view the
  GIS over given maps

Results

• Successfully surveyed remaining streetlights in
  the city in year 2
• Averaged approximately 165 lights per day
• Completed mapping of all street lights in
  Minneapolis, and is now in the process of being
  imported into GIS

Benefits of Project

• All street lights on one map
• Visual Representation of lighting grid
• Easier light pole identification
• Ability to display queries of lighting data
• Changes in real-time
• Faster service location for maintenance work

18
The Next Phase

• Implement a labeling system to affix a barcode to
  each light pole
• Incorporate into 311 and Gopher State One
• Street lighting information available to
  enterprise
