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.

3 Current Tests:
• Capture bldg for pilot area in De Soto.
• Capture bldg for part of a tile that Harden is delivering (J13) and compare.
• Automate building permit point file and create “dummy” bldgs.

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

It’s Not All Bad!
Plani Editing

Challenges:
• Exporting back to tiled covs for legacy apps.– Added SectID field.– Problem with layerexport on large extent.
• Exporting to DXF with attributes retained.– Rebuild AAT on conversion.– Export new/edited data to separate file.

Practical Implications:
• Will a mix of feature types be helpful?
• Will AAT drop cause any problems?
• Will this method of update be worthwhile?
• Will mixing sources cause problems?
• Could maintenance be distributed?
• How do you place “dummy points”?
