Re: OSI Consultaion Process

Following up ……… The good news is that in the draft new version of the Discovery series 1:50,000, the foreshore has been divided into and depicted as beach, sand and shingle, mud, and flatrock, not just beach / other intertidal. I attach a photo AFTER of inner Dingle Bay from the sample sheet 78 sho...

Re: OSI Consultaion Process

Arising out of my having recently registered via Mountaineering Ireland for the OSI survey I have received two draft new Discovery sheets. First sight reaction : nice paper, no underwater contours. In an exchange of correspondence in the Irish Times in August 2009, copy attached, OSI let things rest...

OSI Consultaion Process

Mountaineering Ireland have just published a newsletter in which there is the ability to give feedback to OSI on the recent revamping of all their map types including consolidation / integration of data at all scales, which sounds momentous. A hobby horse (OK, yet another one) of mine and surely of ...

Oileáin News

Oileáin (the soft copy, on-line at www.oileain.org), continues to evolve. It now features 591 islands and my own personal tally is 519. Its and my own most recent inclusion in Oileáin is Rotten Island in Killybegs Harbour last September. There is a 2,000 print run of O2 underway. That makes 4,600 wh...

Oileáin Reprint

Oileáin is about to undergo a substantial (second) reprint which means two things : First it means that Oileáin a Dó will be outperforming Oileáin a hAon , which was never expected. Perhaps its some sort of offshoot of the Covid ? Second, because its a large enough reprint, 1,000 copies, publisher ...

Amphidromic Points

Amphidromic Points, as i am sure we all know well, are points on the surface of the earth palpated by the moon (that's close enough I hope). At an Amphidromic Point there will be zero up and down tidal range (caused by the moon), but at which the time at which the side to side tidal movement changes...

Oileáin

Brexit is coming so I bought in a heap of Oileáins to save me registering and form filling and generally being messed about by the big event (I doubt that tariffs will be the big issue?). Rumours reaching me that Oileáin is out of print and generally unavailable are untrue. The printer is Polish the...
