MAPS on DEMAND (MoD)(Automated Generalisation)
Presentation to Hubei Province Delegation
Background• 1107 Topographic maps covering NSW
• Maps at three scales;– 1:25,000, 1:50,000 and 1:100,000
• All map production from ESRI geodatabase
• Geodatabase currency maintained on theme basis (risk demand driver)
Maps on Demand Driver’s
• Map date currency range 1972 – 2009
• Maps are based on two datum‘s AGD 66 & GDA 94
• Cost of manufacture (Cartographic Overhead)
• Manufacture cycle times = 17 years
• Income
• Asset Management (Accrual Accounting Output Based)

Benefits of Generalisation• Removal of risks associated with;
– Heterogeneity (differing datums = differing coordinates)
– Currency
• Drive down Costs– Manufacture– Asset management
• Manufacturing flexibility and speed to market (Regnauld, N 2007, no pagination)
Presentation to Hubei Province Delegation
Generalisation Options• Agent model (Ruas, 1999)
• CartaCam model (Duchene 2004)
• Workflow filtering (Burghardt &Neun, 2006)
• Global generalisation (Sester 2002, Harrie & Sarjakoski 2002)
• Elastic Beam (Bader 2001)
• GAEL( Gaffuri 2006)
• Ad hoc Generalisation (Touya 2007 & Haurnet 2007)

LPI Generalisation
• LPI has adopted an ad hoc approach– Data model modified to include relative
importance attribute• Attribute domain range 1 to 10
Presentation to Hubei Province Delegation
LPI Approach
• Create annual generalisation from Topographic geodatabase;– A4 Size (1:25,000, 1:50,000 &1:100,000)– Geo-PDF format– NSW Lamberts Projection– Map Grid Australia Coordinates– Discoverable via LPI Spatial Information
Exchange (SIX)– Purchasable via e-commerce extensions to
