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

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

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

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
