The document discusses the UKMap program, which focuses on creating a multi-layered mapping database to improve the representation of complex 3D environments within a 2D framework. It outlines the ongoing development of mapping specifications that aim to handle interconnectivity between various features and the challenges this presents. The initiative, celebrating 50 years of the British Cartographic Society, also includes plans for a competition to encourage innovative cartographic solutions.

The Problem(s) • How to handle multiple overlaying, but not necessarily inter-connected, features in 2D mapping 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 1963 – 2013 CELEBRATING 50 YEARS OF THE BRITISH CARTOGRAPHIC SOCIETY software solutions?

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 ? 1963 – 2013 CELEBRATING 50 YEARS OF THE BRITISH CARTOGRAPHIC SOCIETY another?

Each feature has a position relative to Base and if not mapped on base is on the ‘Overlay’
- 11. 11 TODAY, TOMORROW AND BEYOND . . . 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 TODAY, TOMORROW AND BEYOND . . . Principles to mapping (2) • Identify all features at different levels below ground and map each independentlyp p y • 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 1963 – 2013 CELEBRATING 50 YEARS OF THE BRITISH CARTOGRAPHIC SOCIETY or more layers • Common reference attribution is used to establish linkage
