New Cartography in Digimap - Geoforum 2016 - Tim Urwin
- 4. • Original Ordnance Survey published MasterMap style
• Only change was to building text colour (red instead of
black)
• It’s been in Digimap for 10 years (drawn by three different
GIS systems)
- 5. Design Brief
• Can you make it more consistent and a
‘better’ map?
• Has to make annotations stand out
more and not contrast as much.
• Would like some synergy with OS VML
Raster.
- 6. What were the problems with the style/implementation?
• Colour consistency/choice
– Clashing colours
– Non-consistent colours
• Symbolisation issues
– Vegetation symbols/size
• Not exposing the richness of the data
– Several features grouped together
• Text
– Limited styling differentiation and size
- 20. Greyscale Backdrop
• Style had to work across a large scale range
• Had to use only OS Open products
– Open Map Local, Vector Map District and Strategi
• Had to have consistent style across products
• Wanted it to provide a ‘backdrop context’ rather than full on
mapping
• Look nice
- 22. The 3 OS Open Products: Strategi, VMD and OML
- 24. MasterMap Schema 9 Areas
• Agricultural Land
• Structures:
– Aqueducts, Bridges, Chimneys, Cranes, Cross, Electricity
Sub Stations, Fords, Gas Governor, Locks (and gates),
Masts, Reservoirs, Sloping Masonry, Tanks, Wells
• Natural features:
– Static Water, Waterfalls, Marsh, Reeds and Saltmarsh,
Springs
• Surfaces:
– Mud, Shingle, Sand
– Landfill, Mineral Workings, Slag and Spoil Heaps
- 25. Mastermap Schema 9 Lines
• General features
– Cattle Grid, Conveyor, Cranes, Line of Posts, Lock Gates,
Slipways, Sloping Masonry
• Water features
– Drains, Collects, Conduits, Fords, Leats, Weirs
- 26. MasterMap Schema 9 Points
• Structures
– Capstans, Chimneys, Cranes, Crosses, Flagstaffs, Fords,
Fountains, Gas Governors, Letter Box, Masts, Mooring
Posts, Poles, Posts, Public Conveniences, Public
Telephones, Signals (Rail), Tanks, Weirs, Wells, Wind
Turbines
• Landforms/Natural
– Caves, Collects, Fords, Issues, Sinks, Springs, Static Water,
Waterfalls (vertical)
- 27. Why is schema important for cartographic representation
• Differentiate between agricultural and
natural land.
• Some of the intelligence in the data is
migrating from text features to
attribution (e.g. sand).
• Fewer black lines.
• Fewer generic black dots.
