Ongoing Plani Editing

1
Ongoing Plani Editing

• Goals
• Update some Plani features at an increased
  frequency.
• Update more extent of Plani (more than 50 square
  miles).
• Use available sources of information to do
  smart updates.

2
Plani

• Results
• Some Plani will be dynamic (i.e. bldg, edge,
  obld, veg?)
• New features will be less accurate.
• New features may still need to be replaced with
  accurate inventories at a later date depending on
  needs.

Plani

• 2 Pilot Tests
• Capture bldg for pilot area in De Soto.
• Capture bldg for part of a tile that Harden
  delivered (J13) and compare.

Plani De Soto

• De Soto Pilot Area
• 8 square miles.
• Estimated 256 building permits from 1998 to 2002.
• 342 changes. Approximately 311 buildings added,
  31 updated, 79 deleted.

15
Plani

• Countywide
• AIMS created or altered 15,535
• Of these 2,538 are changed records
• Therefore 12,997 new buildings
• Approximately 5,625 deleted

Time Cost Analysis

• Estimated Time
• 500 X 1.5 hours/tile 750 hours.
• Actual Time
• 7 editors totally approximately 425 hours!

17
Time Cost Analysis

• Estimated Cost
• Harden estimated 51,604 to update bldg and edge
  on the remaining county (approximately 450 sq
  miles)
• Actual Cost
• 425 hours X an average of 30/hr 12,750

18
Time Cost Analysis

• If bldg and edge are equal in time then Hardens
  estimate was 25,802 for bldg alone.
• We saved approximately 13,052!
• Opportunity Cost.
• Distributed data maintenance.

19
Next Steps

• Rollout updated bldg information.
• Coordinators
• myAIMS
• Engineering and map requests

20
Next Steps

• Consider capturing edge.
• How do you tell gravel from paved?
• What scale should you be zoomed to?
• Where does a road stop and a parking lot start?
• Is it better to zoom in, move the magnification
  window or pan the regular window and let it
  redraw in the magnification window?

21
Next Steps

• Prepare for faster turnaround off of 2005
  photography.
• Review building permit point generation.
• Photography in SDE.
