The elevation does not correspond with the estimated elevation (-9999 metres (-32805 feet) -- source Geonames) at that point. Either the location or the elevation (or both) are almost certain to be incorrect. Please use the 'send the updated information' link below to update the location or elevation.
The site location should be at the mark shown -- or very close. Clicking within the map area (or you can drag the 'EHHW' marker) will display the latitude/longitude of that point.
If the displayed location (or elevation) of the weather observing location is incorrect, please drag the marker to the right location (or click in the right location), and then send the updated information. Please note that we are trying to spot either the Stevenson Screen (or equivalent) or the location where the barometric readings are taken.
Can you help with location quality? Please indicate if the marker on the map points at the weather instrument cluster:
The best way to get elevation is to consult a topographic map. Make sure that you know whether the contours are marked in feet or metres. Note that handheld GPS receivers do not provide readings of elevation accurate to better than 10-20 metres (technical discussion). If you do not have access to a topographic map, then a GPS receiver is acceptable, but make sure that it is operating in 3D mode and let it average the position for at least five minutes.
For more information on reading maps, please see the Topo Map Reading Guide -- in particular it discusses how to read contours.
