The UKMap Programme
Conceived in 2007 with Edition 1 of the Specification
Data capture commenced in early 2008
Announced in June 2009
Edition 1 published in November 2009
Edition 11 to be published September 2013
Initially London captured
1963 – 2013 CELEBRATING 50 YEARS OF THE BRITISH CARTOGRAPHIC SOCIETY
Extended into other areas, including rural locations
First overseas pilot in progress

The UKMap Principles
The idea of multiple map layers tied together by
tt ib tiattribution...
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
polygon

Polygons making up a residential property can be
subdivided by ‘building’, ‘paved areas’ and
‘vegetation’

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

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?

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

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

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
