Vicmap Features of Interest(VMFoINT)
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?
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.

Main Uses and Products
3. Vicmap Features Uses – Where is it? What is it?
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
NEW FIELDS
FIELD Data type NULL Column Description
FEATURE_SUBTYPE Varchar2 (30) Y Feature subtype
AUTH_ORGANISATION_CODE Varchar2 (4) Y The code of the Authoritative Organisation where record sourced
AUTH_ ORGANISATION _ID Varchar2 (30) Y The identifier of the Authoritative Organisation’s record – will enable updates and links
VICNAMES_ID Y Official Name sourced from Geographic Names Register

Vicmap FeaturesVicmap 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
1. Establish GNR links to all Vicmap Topographic Named element.
2. Named Feature ID is unique across all datasets and maintained.

FoINT
VMFoINT has moved from a map layer to a full GIS modeluseable, maintainable, sustainable
VMFoINT is authorative
VMFoINT is NOT a wiki
VMFoINT has created a structured and expandable feature code library
Standards, QA processes, Search and management capabilities
VMFoINT is maintained and maintainable long termEg. NES, VSC Custodianship Program, PIP, GNR, CIP
