About this reading
The elevation is the value of the GMTED2010 terrain grid (USGS/NGA, 30 arc-second cells of about 1 km) at Merthyr Tydfil's recorded coordinates. It is the height of the ground in that cell, not of any building; a town on a slope spans several cells, and the range above says how much that matters here. GeoNames' reading of 186 m comes from a finer 90 m SRTM grid at the point it records for the town, which may sit a few hundred metres from ours; the two agreeing to within a few metres is the usual case on flat ground, and a larger gap means the ground is steep.
