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.
Plani Editing

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.

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.

Plani – Harden overlap
Harden Overlap Test:• # of Buildings in J13: 491• # of Buildings done by
Harden: 81• # of Buildings done by
AIMS : 84• Difference: 3

Countywide:
• AIMS created or altered: 15,535
• Of these 2,538 are changed records
• Therefore 12,997 new buildings
• Approximately 5,625 deleted
Plani Editing
Time & Cost Analysis
• Estimated Time– 500 X 1.5 hours/tile = 750 hours.
• Actual Time– 7 editors totally approximately 425 hours!
Plani Editing
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
Plani Editing
Time & Cost Analysis
• If bldg and edge are equal in time then Harden’s estimate was $25,802 for bldg alone.
• We saved approximately $13,052!
• Opportunity Cost.
• Distributed data maintenance.
Plani Editing
Next Steps
• Rollout updated bldg information.– Coordinators– myAIMS– Engineering and map requests
Plani Editing
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?
Plani Editing
Next Steps
• Prepare for faster turnaround off of 2005 photography.– Review building permit point generation.– Photography in SDE.
