  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.

  3. 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.

  4. Plani – De Soto

  5. 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.

  6. 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

  7. Plani Examples of edits: • New Buildings

  8. Plani Examples of edits: • Building Expansions

  9. Plani Examples of edits: • Building Changes

  10. Plani Examples of edits: • Building Deletions

  11. Plani Challenges of editing: • Photo parallax

  12. Plani 2003 Ortho Challenges of editing: • Photo parallax 98-2000 Ortho

  13. Plani Complications of editing: • Tree cover

  14. Plani Complications of editing: • Small buildings

  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

  16. 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 Harden’s 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.
