I'm doing the world premiere of "What happened here - a retelling of Lear" tonite, and the second and final-for-us-but-hopefully-not-for-the-author show tomorrow nite. Sunday is a rest day :oD First Sunday without either rehearsal or show since nehwwonktnodi...

[Sierra Mike] I answer to INJ mostly. In fact elsewhere I tend to be just NotJohn - Im not sure why I've got the 'Im' in the Morniverse.
I'm also a bit of a cartophile - I've got 2 shelves devoted to them at the moment. I have a version of the Stevierule^TM which goes 'No Map no Trip'.
OS maps now cover the whole of the UK at 1:25000 and are so much clearer than the 1:50000, which I use mostly for cycling. I still love the 1 inch tourist maps with the colouring & hachuring but you can't beat the large scale for navigating in mist/cloud. Also you get spoilt by the quality of orienteering maps 1:10000 or 1:15000 using specialised software, where you can navigate to the nearest 10 metres.

[S M & INJ] These come in an attractive orange cover, far nicer than the 1:50000s' lurid pink.

I have inherited dozens of OS maps from my cartophilic Dad, mostly 6th Edition but some older than that (pre-war). The expansion of some towns is phenomenal. Crawley, for example, was a compact place with a station and a high street but is now a vast, amorphous sprawl. The new 1:50,000 and 1:25,000 maps are more accurate and detailed than their older counterparts, particularly in regard of contours. There are sad (old meaning) bits such as "Course of old railway" and "Mines (disused)" (Yeah, so's mine). Even though the OS Grid has always been metric I'll never get used to heights in metres. My house is at 557 ft, not 169 metres, so I claim the title of Highest-living Morniverser.
[Non-mappies look away NOW] The OS Grid is a Transverse Mercator projection, prime meridian 2°W, based on a model of the Earth developed by Sir George Airy over 100 years ago. It's a tiny bit different from modern values both in size and degree of flattening. There is a scale reduction of 0.04%, presumably to allow for the expansion of the scale in the projection away from the prime meridian.

[Rosie] I cannot claim such a lofty domicile, but two minutes' drive gently uphill takes me to this point, Cossham Hospital, the highest point in Bristol at 369 feet (112 meters). On a clear day the views over the city, the Severn Valley, Forest of Dean and even the Brecons are excellent. Oh, and thanks for the techie stuff!
