  1. TASMANIAN JURISDICTIONAL UPDATE DCDB National Workshop 28-30 July 2010 Andrew Tomes Manager - Spatial Data & Julian Gill Program Leader - Cadastral & Transport Department of Primary Industries, Parks, Water and Environment

  2. Introduction – Topics to be covered in presentation • Development of DCDB • Cadastral Model overview and Managing Environment • Delivery of Cadastral Data • Cadastral Maintenance and issues • Strategies to improve spatial accuracy • Achievements, Issues, Challenges and direction ahead • Questions DCDB Workshop – TAS Presentation

  3. CADASTRAL MAPPING BACKGROUND DCDB Workshop – TAS Presentation

  4. CADASTRAL MODEL DIAGRAM DCDB Workshop – TAS Presentation

  5. THE CAD_TYPE – ALLOWS CLASSIFICATION INTO THEMES • CAD_TYPE 1 – PRIMARY CLASSIFICATION • CAD_TYPE 2 – SUB CLASSIFICATION • The combination can produce many discreet deliverable datasets. • Cadastral Parcels is the key framework cadastral dataset • Other data themes extracted on the Cad_type • Having all the themes managed in the one environment ensure topological consistency between layers when delivered. DCDB Workshop – TAS Presentation

  6. CADASTRAL PARCELS – THE “JIGSAW” DCDB Workshop – TAS Presentation

  7. CAD TYPE EXAMPLES DCDB Workshop – TAS Presentation

  8. OTHER DERIVED DELIVERABLE CADASTRAL DATASETS • Easements • Crown Leases and Licences • Private Reserves incl. Conservation Covenants • Ramsar Wetlands • World Heritage Area • Public Land Classification (Reserves) • Local Government Area Reserves (Public Open Space) • Some Miscellaneous Categories • LGA, Locality, Electoral Boundaries maintained as discreet layers and over time may not align with parcels DCDB Workshop – TAS Presentation

  9. DATA MANAGEMENT PRINCIPLES • Data is managed within Data Management Server and separated from data delivery • Business rules - consistency and some enforced validation • Stores Feature Based Metadata (FMP’s) • Pessimistic Locking for editing sessions • QA procedures prior to checking in of data • Created_On and Retired_On dates provide temporal change history • Changes are replicated into Data Delivery Server nightly • Delivery data is joined with code list values and split into various standard deliverable data sets DCDB Workshop – TAS Presentation

  10. DELIVERY OF CADASTRAL INFORMATION • Data replicated nightly to Data Delivery Server • Automated delivery using FME through FTP server • Customised to client requirements • Service Level Agreements for most clients • LGA’s dependant upon data • LISTMAP displays cadastre and associated layers • Automated Map Production processes for 1:25K mapping DCDB Workshop – TAS Presentation

  11. The Progression of Cadastral Maintenance • : Original Cadastre Not Upgraded DCDB Workshop – TAS Presentation

  21. Missing title project: DCDB Workshop – TAS Presentation

  22. WHERE WE ARE AT NOW • Current management environment • Client – ARC GIS 9.3 • Server – Arc SDE 9.3 • Oracle 11g (SDE Binary) • Over 2 million boundary segments in Datamodel • 21% of boundaries are within 1 metre of true position • 380,000 parcels in Cadastral Parcel layer DCDB Workshop – TAS Presentation

  23. ACHIEVEMENTS, ISSUES AND CHALLENGES OF PAST YEAR • Branch Restructure resulting in new Program Area to manage Cadastre, Transport and Addressing maintenance • Significant staff reduction from salary restraints resulting from 2009 economic crisis • Efficiency gains through combining cadastral and road centreline maintenance and multi-skilling of staff • Gains in improvement of cadastral spatial and attribute accuracy through routine maintenance, joint projects and targeted replots • High reliance upon cadastre data from clients particularly Councils.
