DSE Fire & Emergency Management
Responsibilities:
• Fire prevention (prescribed burning)
�Autumn and Spring seasons
�Low intensity
� Treated over 150 000ha this fire season
Orbost Apr 08
DSE Fire & Emergency ManagementResponsibilities:• fire suppression on public land
� Last 5 Years� Assist SES with Flood Mapping

Fire Spatial Information Systems
Firemap
• Web Based�ArcIMS�IMF�ArcSDE
Main Uses:• Burn Mapping• Incident Mapping• Map templates
Fire Spatial Information Systems
• Maps fires directly into ArcSDEDatabase
• Relies heavily on Vicmap for base layers
Fire Spatial Information Systems
Incident Mapping DVD
• Standalone Mapping
Application
• ArcGIS ArcView
• Compressed File Geodatabase
• Use: Incident Mapping
Use of Spatial Data
Fire Themed�Fire History� Planned burns� Fire Infrastructure� Administrative Boundaries
Base Data�Vicmap�Public Land�Satellite Imagery� Aerial Photography
Use of Spatial Data
The need to display a theme at all scales
• Eg. Roads�5m – 1m Road500�1m – 100k GA250�100k – 10k – Vicmap Transport
• Lose continuity of map display
• Temptation for businesses to create generalised simplified data sets.
Display Issues
• Rendering based on road
class category Eg. Freeway, Highway, Arterial
Firemap Scale: 1: 350000
Missing Roads
Vicmap Lite
Overview
• Generalised Statewide data sets
• Suit scales 250k – 5m
• Themes include � Transport� Hydro� Relief� Admin� Vegetation� Features� Hillshade
Firemap Dev with Vicmap Lite
Vicmap Lite - Scale Use
• Scale use code - controls the level of content
• Class code – Eg. Freeway, Highway, Arterial
• They are different!
Vicmap Lite - Scale Use
• Scale use code controls the level of content
Firemap – GA250Map Scale 1: 300k
Firemap – Vicmap liteMap Scale 1: 300k
Vicmap Lite - Scale Use
Firemap – GA250Map Scale 1: 500k
Firemap – Vicmap liteMap Scale 1: 500k

Vicmap Lite – Performance
• Reduced number of arcs
• Faster rendering for web and GIS desktop apps
• Improved labelling1 Arc
Vicmap Lite – Performance
• Reduced number of vertices
• Reduced file size
Vicmap Lite – Other Advantages
• Maintained Product
• Regularly Updated
• Cartographic Improvements through content control
• Ezi Road label
• Easy to Use
Potential Future Directions
• Take up of Vicmap Lite may increase if other scales are considered
� 250k – 100k � 100k – 25k
• Other data sets�Eg. Fire History..
Transition Plan
• Remove the old road500, hydro500… from existing applications
• Replace with Vicmap Lite for web and GIS desktop applications
• Target - August 08.
Transition Plan
Aug 083. Migration to Prod
July 082. UAT Testing
July 081. Configuration into ArcGIS project
ArcGIS Standalone Incident Mapping
Sept 083. Migration to Prod Firemap

Schedule
Main Points
• Scale use Code - controls the level of content
• Improved cartographic display
• Vicmap Lite regularly updated
• Integration into Fire Spatial Systems before 08/09 fire season
• Faster and more useful incident maps
