1. A truly automated system for New Zealand’s Topographic Maps Geoff Howard, Fran McNamara and Graeme Blick Land Information New Zealand November 2009

2. Options considered 1.A one-off enhancement of the NZTopo Database required the enhancement of LINZ’s 1Spatial LAMPS2 system and the creation of rules, methods and symbolgies including text placement to deliver cartographic quality outputs from the database. 2.Continuation of outsourcing map production required external contractors to use LINZ data and produce the required maps and arrange printing on a sheet by sheet basis

3. Key Considerations The datum for New Zealand’s mapping had changed A global projection was needed Printing technologies are making it difficult to print large format maps Plate making from traditional film positives is becoming difficult A well structured Topographic Database existed Increase the frequency of map editions within existing budgets

4. Cartographic Challenges Develop comprehensive documentation and specifications LINZ and 1Spatial project teams would need to be aligned Develop ways to represent our data without altering the spatial location Develop rules and tools that allowed text to be placed cartographically Develop a comprehensive list of object display priorities Develop representations based on multiple objects and combinations of attributes from these objects Text Masking Generate Grid and Graticule Adding the Relief Shading Adding the legend and marginalia

5. The Topo50 Map Automatic Grid And Graticule Values

6. Resolving Symbology Clashes Embankments

7. Creating Representations From Multiple Objects Ford

8. Modifying Representations Based On Multiple Objects Cliff

9. Partial Modification Of Representation Based on Multiple Objects Rocky Coastline

10. Creating Representations Based On Multiple Object Representations Bridge

11. Creating Multiple Representations On A Single Object Contour through ice

12. Influencing text display based on existence of another object Road names in residential areas

13. Boosting Representations Roads over and under each other

14. Text masking Text over a bitmap fill

15. Text Masking Other examples from the Prepress showing the ability to alter the mask depending on the colour of the linework beneath the text

16. Text Masking Black text masking black linework, but not blue

17. Text Masking Black saddle symbol masking black road casing, but not red road infill

18. Automating The New Topo50 Maps

19. Raster images Tiff format (the whole map including legend and index) GeoTiff format (spatial data area only with georeferencing)

20. Communicating The Change

21. Warehouse & Distribution

22. Resource material

23. What we achieved Coordinated support and adoption of a new Topographic Map series by Defence & Emergency service organizations Developed a truly automated production flow-line Integrated topographic maintenance & production Improved topographic capability, quicker cheaper production of paper maps & produced GeoTiffs and Tiffs for free dissemination Produced and warehoused 451 Topographic Map titles Distributed over 100,000 maps in one week Successfully replaced a national map series on 23 rd Sep 2009
