Developments inTopographic

Data Management& Mapping

inQueensland Australia

• Issues• Longer Term View



The Size Problem

Queensland (1.853m km2) is a large state of Australia and is roughly equivalentin land area to the whole of Indonesia ( 1.9m km2)



OR the total area of:Malaysia (0.329mkm2) +

Thailand (0.514mkm2) +Myanmar ( (0.678mkm2) +

Cambodia (0.181mkm2) +Vietnam (0.329mkm2)

Population of only4 million people!



•The capture, management andmaintenance of topographic

information over such a vast areahas been a struggle.

•After 25 years, only managed to

map 10% of the total area ofQueensland – (Green – 25kscale)

•Struggling to maintain that.



Initiated a Business Process Review(BPR) – BPR Findings:

• Current Topographic Program – FAILING!

– Limited Coverage of State – Struggling to Maintain Existing

Data Currency

– Programmed Coverage –

Patchy and Inconsistent



• Automation – Key Changes

– Focus on Data Capture and less on Specific Map Products

– Capture Topographic Data in Themes

– Capture Data to a Seamless Database &Target Whole of

Queensland Coverage by Themes where available – Utilise all Sources of Data, taking advantage of existing

data sources – if someone has the data obtain it fromthem – don’t re-develop the data – don’t go through timeconsuming identification processes

– Simplify Data Capture

– Let contours portray the geography – limit symbology – Automate Data Capture as much as possible – utilise

satellite & aerial imagery – utilise automated imageryclassification techniques

– Complete Data Feature Attribution – smart data

– Limited Field Check – if any – Alignment of Data Capture with Government Priorities togarner support

– Risk a Lower Level of Cartographic Quality in order toAchieve the Objective of Improved Topographic DataCurrency and Coverage

BPR Findings:



Progress withAutomated Topo Processes

• Concept & Workflow Changes – theme basedseamless data capture, more coordination required,acquisition of data from new sources – point of truth

• Established New Relational database – InformixDatabase

• Data being converted with full data attribution – full metadata, intelligent data

• New compatible data structure established

• Text manipulation software in place – Label-EZ,-Contour & -Edit

• VBA tools developed to automate basic repetitive tasks

• View/Compilation environment – Web Browser,

GIS system



• New efficiencies being realised - Considerably lessproduction time

• A degree of “Scalelessness” - Greater variety of mappingoptions – Scale, Layers/Themes and Formats

• Cost effective print runs – print only what you need – print/plot on demand

• Data capture coordination, sourcing & sharing with otheragencies – reduced duplication of data capture – easysharing

• Similar quality product to the old manual paper basedproduct

• Digital topo data allows integration with other systems andother data – finding new uses for topo data – newcustomers – new importance to topo data capture

• Compatible with the trend to on-line mapping

Issues

• Increased Requirement for Coordination - Process Coordination –

Workflow Coordination – Coordination with aligned business areas• The new sources of data - not always so good – rely on principle of

point of truth for data sets

• Perfectionists• Distractions – higher priority work

• Need to continuously sell the benefits of developing and maintaininggood quality spatial information – economic benefits as well as social

benefits



Longer Term Prospects

• Greater Coverage & Currency of Topo Data for Queensland

• Automatic feature identification from sensor data

• Swath of 25k data & map products along coastline

• Introduction of 50k scale data & map products further inland and

parallel to coastline• Print/Plot on Demand Capability to Map Shops – from data

• On-line access to data?
