1. TASMANIAN JURISDICTIONAL UPDATE DCDB National Workshop28-30 July 2010 Andrew Tomes Manager - Spatial Data & Julian Gill Program Leader - Cadastral & Transport Department of Primary Industries, Parks, Water and Environment

2. 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 INTRODUCTION – TOPICS TO BE COVERED IN PRESENTATION 2 DCDB Workshop – TAS Presentation

3. CADASTRAL MAPPING BACKGROUND 3 DCDB Workshop – TAS Presentation

4. CADASTRAL MODEL DIAGRAM 4 DCDB Workshop – TAS Presentation

5. 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. THE CAD_TYPE – ALLOWS CLASSIFICATION INTO THEMES 5 DCDB Workshop – TAS Presentation

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

8. 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 OTHER DERIVED DELIVERABLE CADASTRAL DATASETS 8 DCDB Workshop – TAS Presentation

9. 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 DATA MANAGEMENT PRINCIPLES 9 DCDB Workshop – TAS Presentation

10. 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 DELIVERY OF CADASTRAL INFORMATION 10 DCDB Workshop – TAS Presentation

22. 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 WHERE WE ARE AT NOW 22 DCDB Workshop – TAS Presentation

23. 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. ACHIEVEMENTS, ISSUES AND CHALLENGES OF PAST YEAR 23 DCDB Workshop – TAS Presentation

24. WHERE WE WANT TO BE IN THE FUTURE 24 DCDB Workshop – TAS Presentation
