Notes on Channel Islands mapping ================================ J.G.Harston -- mdfs.net/jgh This is an ongoing personal experimental development project to create a full set of 1:50,000 maps of all of the Channel Islands areas on the UTM 1km mapping grid, including offshore islands, rocks, reefs, etc. These maps be used for noncommercial purposes. Browser interface ----------------- map.php?g=gridref&z=zoomlevel gridref is 6-figure grid reference within WV grid square zoomlevel is map scale in thousands, currently supports z=50 and z=100. Update history -------------- 18-Jun-2010: Guernsey scale and gridlines confirmed from 1961 OS 1:25,000 mapping. Cleaned up Minquiers, Ecrehous and Casquets outlines. 10-May-2012: Jersey initial visual check with gridlines on 2009 SoJ 1:25,000 mapping. 12-May-2012: Scaled and aligned Sark correctly with grid lines Initial mapping of Roches Douvres & Barnouic. 13-May-2012: Added eastern maritime border to Guernsey (Aldernay) To do ----- Check scaling and grid for Alderney. Map Hern and adjoining islands. Add offshore islands and reefs to Jersey and Guernsey. Increase resolution of Minquiers, Ecrehous, Casquets. My mapping shows a large island within the Ecrehous - I think this is incorrect. Add Guernsey western international maritime boundary Add Jersey international maritime boundary Add Guernsey/Jersey balliwick maritime boundary.
