The product is a full colour, hollow 3D terrain model of Crib y Ddysgl, Y Lliwedd (the peaks on the famous Snowdon Horseshoe ridge walk).
Upper surface: Geological map showing and labeling the rock type (with BGS LEX codes) of bedrock strata as well as artificial features and linear features such as faults, folds and mineral veins.
Underside: labelled grid lines, the names, positions and heights of all the Hewitts (Hills in England, Wales and Ireland over Two Thousand feet), a compass arrow indicating the North direction and an acknowledgement to the British Geological Survey for the map imagery with their copyright notice
North wall: an acknowledgement to the Ordnance Survey for the elevation data with their copyright notice
East wall: the scale of the model
South wall: the name of the main peak in both English and Welsh and its height in meters and feet
West wall: the branding "Mountain Shapes"
Horizontal scale: 1:50,000
Vertical scale: 1:50,000
Material: Full Color Sandstone - a hard brittle plaster-like material with a granular look and feel. The model could be damaged if dropped onto a hard surface, knocked by a hard object, exposed to water, heat or strong sunlight for prolonged periods.
Size of area modelled: 6 km x 3 km (120 mm x 60 mm in model)
Thickness of walls: 2 mm
Volume of material: 21.6 cc
Weight of model: 36 g
Grid reference of centre of model: SH 62000 54500 (262000, 354500)
Source of elevation data: Ordnance Survey OpenData Terrain 50
Elevation sampling interval: 50 m (1 mm in model) at the centre of 50 m grid squares with interpolation from neighbouring samples at the edges of the model which are on grid lines, 25 m (0.5 mm in model) from nearest sampled elevations
Maximum elevation: 1,081 m (21.6 mm in model)
Minimum elevation: 66 m (1.3 mm in model)
Source of map imagery: British Geological Survey DiGMapGB-50 1:50,000 scale geological map
Source of mountain attribute data: The Database of British and Irish Hills
KEY: A key to the BGS geological map can be viewed by clicking on the small "Legend" image just underneath the rendering of the model at the top of this page. The first part of the code in the key (before the hyphen - which is also the code shown in the labels on the surface of the model) is the LEX code used in the BGS Lexicon of Named Rock Units database and the second part of the code (after the hyphen) is the RCS code used in the BGS Rock Classification Scheme. More information can be obtained by entering the appropriate codes in the following web pages:
