Just saying hello - since your talk at the September 2010 OSSbarcamp (and being provided a BlackBerry from work which can do GPS traces) I've been sucked into OSM, currently mapping around where I live in Naas and my workplace at Cherrywood in D18.

Hi Dermot, the Key:ele was defined as "height above sea level"  I added a few words to explain the difference between WGS84 geoidal an ellipsoidal heights. Did you import the ele-Tags for the Irish mountains? There are values as WGS84 ellipsoidal heigths and values in the Irish national system. The problem is, that the WGS84 ellipsoidal is duplicated into the ele-Value. To be conform with the definition, it should be the WGS84 geoidal value. The difference is approx. 50m. Can you help to harmonize the ele-Values? Is there a simple script/bot solution? Currently, the renderer just puts the ele-value on the map. But automatic processing (i.e. Smartphone-App tells you "still 50m to the peak") only works with standardized values. Regards, --Oosm12 (talk) 23:05, 4 November 2013 (UTC)
