Y Garn - Relief

OVERVIEW:

The product is a full colour, hollow 3D terrain model of Y Garn based on Ordnance Survey elevation data draped with an Ordnance Survey OpenData 1:50,000 map image.

It is an ideal gift for a mountain walker, mountain lover or a map enthusiast, or an attractive souvenir for anyone who has visited the northern part of the Glyderau range and has admired the shapeliness of Y Garn and its neighbouring peaks. The model can be put on display as an eye-catching ornament or memento that will be sure to be a conversation piece. It could also be a useful tool for a geography teacher or navigation instructor who wants to demonstrate how 3D terrain relates to its representation on maps.

The vertical scale of the model has not been exaggerated and the model is therefore is accurate to scale. The 3D model is aligned to the UK National Grid with the 1 km grid lines etched on the bottom of the walls of the model.

In addition to Y Garn, the model also features Elidir Fawr and Foel-goch. The model can be placed alongside the Snowdon - Relief model or the Glyder Fawr - Relief model to form a larger "model" and, if all five Welsh 3000 ft Peaks models are purchased, it could form one large "model" that includes all the 3000 ft peaks in Wales.

SURFACE DETAIL:

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 Ordnance Survey for the OpenData 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 and its height in meters and feet
West wall: the branding "Mountain Shapes"
