The Ordnance Survey, the United Kingdom's mapping agency, bases all elevations including mapped contour lines and spot heights on the mean sea level at Newlyn ( " see Ordnance Datum " ).
23.
Another possibility would be to also weight the'spot heights'by the population of each town, so I suppose I would get something like w = p / d ^ n where p is population.
24.
Heights are taken from the Peruvian IGM 1 : 100, 000 series maps with the OEAV survey maps of the Cordillera Blanca ( north and south ) used where the IGM maps do not give spot heights.
25.
The clockwise course is in length from the start-line at the TT Grandstand situated on the Bungalow at Hailwood's Height near the 31st Milestone and the UK Ordnance Survey spot height of above sea level.
26.
However most products offer additional functionality such as the ability to takeoff terrain elevation from plans ( using contour lines and spot heights ); produce shaded cut and fill maps; produce cross sections and visualize terrain in 3D.
27.
It is often reported that Moel Sych, along the ridge, is of equal height, but Cadair Berwyn's spot height on the Ordnance Survey maps, where the trig point stands, is not the true summit.
28.
The summit of the mountain is a gentle rise on the plateau and is only made obvious by the presence of an OS map also shows a 936-metre spot height, half a kilometre to the west of the recognised summit.

Multivariate interpolation is particularly important in geostatistics, where it is used to create a digital elevation model from a set of points on the Earth's surface ( for example, spot heights in a topographic survey or depths in a hydrographic survey ).
30.
Confusingly, the Ordnance Survey 1 : 50, 000 scale Landranger map gives a spot height of 856 m at the south-eastern shelter cairn, while the 1 : 25, 000 Explorer map gives a height of 857 m at the north-eastern cairn.
