• All map production from ESRI geodatabase

• Geodatabase currency maintained on theme basis (risk demand driver)

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)

Generalisation Options• Agent model (Ruas, 1999)

• CartaCam model (Duchene 2004)

• Workflow filtering (Burghardt &Neun, 2006)

• Global generalisation (Sester 2002, Harrie & Sarjakoski 2002)

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
