Vicmap Features of Interest(VMFoINT) • Background • Data Uses • Interim Model Development • Vicmap Features of Interest • Conclusion David Blain DSE Vicmap Surveying and Spatial Information Victoria 2008 Summit 17 September 2008
Vicmap is Victoria’s Spatial Framework Information • Single authoritative source • Whole-of-State coverage • Established quality levels • (completeness, reliability, currency, spatial and attribute accuracy) • Accessible and available • Fit for purpose
Vicmap Features - Elements Building Points 516 079 Areas 13 207Built Up Area (BUA) 1 939Geographic Name Register Points 35 587Geographic Labels - Hydro & ReliefLocality Point LabelsLandmark Points 4 997 Polygons 12 047 Utility Points 23 963 Lines 1 812 Polygons4 595614 216 • Vicmap Annual Maintenance: • 70,000 new properties every year • 70,000 new addresses every year • 5,000 new roads every year • DEM creation resulted in an upgrade of Elevation • Hydro – Vicmap Water consultancy and Federal developments • Vicmap Features?
1.5 Vicmap Features Background • History • Created from cultural data captured during production of the 1:25 000 Accelerated Topographic Mapping Program 1974 - 1992. • Data was migrated into a GIS environment 1996. • Subsequent data improvement programs were ad hoc and opportunistic. • Similar and duplicate datasets exist for the same purpose • eg. 000 CPN and ES Points (Single User Requirement) • 2007 Features of Interest consultancy recommended: • Improve / upgrade data quality and supply • Modify / upgrade the data model to adopt a “services” structure • Appoint a Vicmap Features custodial officer with sole responsibility for the product.
3. Vicmap Features Uses – Where is it? What is it? Main Uses and Products
Vicmap Features – Interim Data Model • Addition of Feature Sub Types • Based heavily on the current ICSM and PSMA data models. • No “off the shelf” data model exists • The data model structure reflects fit for purpose requirements • It removes the reliance on variable attribute fields and reference tables • Ensures effective and efficient search and management functionality
Type Whose Asset ID Official Name Where Vicmap Features – Model Enhancements
Vicmap Features • Vicmap Topographic Suite Changes • Changes to Vicmap Features has changed the whole Vicmap Topographic Suite base: • Vicmap Shared • Vicmap Admin (LGA and Locality) • Vicmap Elevation • Vicmap Features • Vicmap Hydro • Vicmap Transport • Establish GNR links to all Vicmap Topographic Named element. • Named Feature ID is unique across all datasets and maintained.

Vicmap Features of Interest (VMFoINT) • Interim Model to New Model • Campus Approach • Parent / Child PFI • Better categories of data with appropriate themes • Emergency Services • Education • Health Care • Industry • Commercial Premises • Recreation • Sporting Activities • No Scale of Capture (Scale Use Code) • Proposal Full Data Model for comment March 2009

Vicmap Features of Interest (VMFoINT) Conclusion • VMFoINT has moved from a map layer to a full GIS model • useable, maintainable, sustainable • VMFoINT is authorative • VMFoINT is NOT a wiki • VMFoINT has created a structured and expandablefeature code library • Standards, QA processes, Search and management capabilities • VMFoINT is maintained and maintainable long term • Eg. NES, VSC Custodianship Program, PIP, GNR, CIP
