CADASTRE STRATEGIC DIRECTIONS WORKSHOPAUGUST 16, 2012Western Australian Land Information System Peter Ingwersen
PURPOSE • To collaboratively identify and consider opportunities for WOG efficiencies in regard to the future usage of the cadastre.
CADASTRE REFERENCE GROUP(S) • Existed at least since 1996, various names • Collaborative initiation/ progression/ implementation of many improvements to cadastre • POSITIONAL ACCURACY IMPROVEMENT GROUP… • - Since 2006 • - Referential topology focus (... of derived datasets) • - Achieved some important wins, but largely tactical
Some priority tasks highlighted by PAIG to be progressed: • Complete Spatial Upgrade Pass 1 • Complete Spatial Upgrade Pass 2 • Provision of easement definition • Improved alignment of cadastre to imagery • Others, including: - Fix the lot areas - Provision of a planned layer - Lot synchronisation
CADASTRAL DATA ACCESS, USAGE (1) • Govt agencies (& LGA’s) access the cadastre differently. • Landgate Extracts: • Govt agencies get extracts of the cadastral data... • 2 get it monthly, 10 – qtrly, 5 – six-mthly, 2 – annually • LGA’s get extracts of cadastre, … mixed frequencies • SLIP … • only 6 Govt agencies access the cadastre as a SLIP svce.
CADASTRAL DATA ACCESS, USAGE (2) • and, several Govt agencies (and LGA’s) not only maintain a local vsn of the cadastre, they maintain it differently: • Nightly, full refresh of locally-held cadastre via SLIP • Maintain local cadastre via Landgate-provided ‘data change files’ • Maintain local cadastre using ‘pre-cal’s • Access cadastre effectively in real-time mode
We have a world-leading implementation of cadastre • We’ve got a very joined-up spatial community • We’ve implemented SLIP • BUT ... we still hold duplicate copies of the cadastre, and duplicate data maintenance activity !! ( since ...??) • Is it time to (re-)explore more optimised WOG access to, and use of cadastral data ...?
Location Information Strategy for WesternAustralia Putting Location into Action • LOCATION INFORMATION STRATEGY … AIMS: • FACILITATE WA’s growth thru better use of location info • ENABLE better informed decision-making • STREAMLINE the capture/ maintenance of Govt data • FOSTER innovative thought, process and practice
We hope to achieve… 2020 ‘ideal-world’ scenario-thinking re cadastral data: • Government and community demands upon cadastral (and related) datasets • Agency capacity to deliver, eg business impact considerations • Explore WOG efficiencies … How will we do things differently in 2020? • ITS NOT ABOUT ‘TWEAKING’ CURR. DELIVERY PRACTICE !
ITS ABOUT… • Strategic wants,… not operational/ tactical wants • WOG perspective • Cadastre, not just Spatial Cadastral Data Base (SCDB) • Blue-sky thinking,… there are no stupid ideas • We’re not trying to solve things here • Open discussion,… leave any sensitivities at door please
