Height errors on Irish summits in German BKG
I have recently discovered that the Bundesamt fuer Kartographie und Geodaesie (BKG) has published a topo map that has erroneous heights for nearly all the Ardeerin summits in Wicklow, Dublin and Wexford; this has been confirmed by BKG themselves, after an original snooty response. I raised the issue with BKG at the beginning of March, but the map is still online - I suppose they can't just pull it without inconveniencing a lot of users. I have no idea if this is just a localised problem - I have looked only at those Ardeerins in my local region.

Most of the errors add typically about 46 to 53 m to the accepted heights, but some heights are almost correct, and there are a few summits that actually get shrunk; so it's not a simple matter of a blanket addition, or a quibble over the geoid in use.

I came across this rather astonishing situation while using PhotoEphemeris, a program to figure out the bearings of sunrise, sunset etc. for photographers: this program just happens to overlay its computed bearings on a topo map provided (presumably free) by BKG.

I hope to hear eventually from BKG just how they screwed up, but in the meantime do not rely on BKG's topo map!

Look out tower. In surprisingly good condition given its exposed location. It is located about 500m directly south of Sturrall summit. Dont miss this as it is worth a visit if doing Sturrall
