The UKMap Principles

The strength lies in the attributes:• 265 land use codes in a 4 level hierarchy• 8 land cover type codes• Creates over 1500 combinations for a single

The Next Generation
• Currently preparing Edition 3 of the Specification
• Planned as major step forward in the way we handle complex 3D environments within 2Drepresentations

The Problem(s)
• How to handle multiple overlaying, but not necessarily inter-connected, features in 2Dmapping terms?
• How to establish relationships between features and objects that do link?
• How to create inter-connectivity through structured attribution?
• How to make the data usable in currently available

Pulling apart the 3D world
• Decisions have to be made:• What is considered to be ground level?• Are there features that are above ground?• Are there features below ground?• What are the relative height displacements between
features, relative to the ground?• Does one feature, like a railway line, exist in all three
levels?• Are there features which connect between one layer and
th ?

The blue line is ground surface or Base level. Each feature has a position relative to Base and if not mapped on base is on the ‘Overlay’

Principles to mapping
• Determine ground level• This may be variable relative to datum
• Map all features at ground level and attribute as the Base layer.
• No overlapping polygons and no gaps
• Identify all features at different levels above ground and map each independently on the ‘overlay’ layer.
• Overlapping polygons permitted
1963 – 2013 CELEBRATING 50 YEARS OF THE BRITISH CARTOGRAPHIC SOCIETY
• Attribution defines level relative to Base• Add relative height code to denote separation from Base

• Overlapping polygons permitted• Attribution defines level relative to Base• Add relative height code to denote separation from Base
• Where features in one map layer connect to features in another layer, locate and add ‘Connectors’
• Connectors are small polygons which join features in two or more layers

or more layers• Common reference attribution is used to establish linkage

Cartographic Challenge
• The complexity of the mapping presents a number of cartographic challenges.
• Multi layer viewsMulti layer views• Dynamic representations• 3D extrapolations• Symbolisation options
• Looking for partners to produce experimental cartographic representations of the Canary Wharf database.
1963 – 2013 CELEBRATING 50 YEARS OF THE BRITISH CARTOGRAPHIC SOCIETY
• Plan to run a competition at the start of 2014 with a significant cash prize to stimulate cartographic innovation
