Plani Editing

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.

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.

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”?
