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
