Hema is a Brisbane-based mapping company transitioning from paper to digital maps. This requires completely redesigning and rebuilding their GIS database to be database-centric rather than product-centric. They integrated data from multiple sources into single feature classes and tables to simplify the data model. Generalizing point of interest and road data was necessary for digital maps. This transition to digital is essential for Hema's future success.

Editor's Notes
Hema founded in 1983
Digital mapping products – gps navigation devices, maps, apps, cloud based services
Centralised data – requires data generalisation process
Generalisation
Only certain roads shown at certain zoom levels
Only certain POIs shown at certain zoom levels and grouped around localities
Only certain topographical points shown at certain zoom levels
Multiple data sources – no single point of truth
Product centric
Desktop based
Heavily reliant on cartographers
Digital output = digitised paper products
Single point of truth – complete redesign and rebuild
Simplified data model
Integrated Roads
26 POI tables to 9. Duplicates removed. Redundancies removed. Rich content – attribution, text, photos, video etc added
Restructured Topo – same attributes across all feature classes
New digital product – designed for digital consumption not digitised from paper product
Move from desktop to server/web based
Data now exposed to more users
Allows faster, more efficient data maintenance
Allows for creation of new, Australia wide fit for purpose digital products
All POIs shown – Too cluttered, duplications
Data Generalisation
Roads – only display certain roads at certain zoom levels
POIs – only display certain POIs at certain zoom levels
Topo – only show certain Topo at certain zoom levels
Fully automated and repeatable
Create buffers around localities, size based on population
INSIDE locality buffers
Join buffered localities with urban area polygons based on name
Remove duplicates and add to locality labels
OUTSIDE locality buffers
Buffer each POI
Remove duplicates
Explorer 150k Map
Single Scale Australia wide Hema Navigator
Includes embedded POIs - generalised
Explorer Map
Multiscale Australia wide
For current Hema Explorer App and Cloud
POIs displayed as floating interactive layer not embedded
For future B2B as TMS, Tiles, API
