Version 1:The original map [ edit ] Version 1: the original map. Who did it? [ edit ] User:SFC9394 , derived from WGS84 data.What's the projection? [ edit ] Unknown. It is raw WGS data and therefore geodesic. What's the problem with it? [ edit ] I think geodesic data implies that the longitude and latitude lines are curves, not straight lines. Usable as a location map? [ edit ] If the bit above about the curves is correct, then no.
Version 2:Mercator map [ edit ] Version 2 with border. Who did it? [ edit ] Me derived from User:SFC9394 's original and a Mercator map produced from public domain map engine at http://www.aquarius.geomar.de/omc/ What's the projection? [ edit ] Mercator from -8W to 0E, 54.5N to 61N What's the problem with it? [ edit ] Mercator projection has latitude and longitude as straight lines, but vertical distances increase the further away from the Equator you go. Usable as a location map? [ edit ] For Equatorial or small countries, yes, but Scotland is far enough away from the Equator and tall enough for this to become an issue. So no.
Version 3:Equidistant cylindrical map [ edit ] Version 3. Who did it? [ edit ] Me derived from a equidistant cylindrical map produced from public domain map engine at http://www.aquarius.geomar.de/omc/ and User:SFC9394 's original What's the projection? [ edit ] Equidistant cylindrical from -8W to 0E, 54.5N to 61N What's the problem with it? [ edit ] In terms of projection, none: equidistant cylindrical is equirectangular (a square on that map would be a square in real life). In terms of user acceptance, this is a problem: people who are used to Mercator or other projections will feel that the country "looks wrong" and object accordingly. There are precedents for this: I believe Russia (a very wide, but not very tall country, proportionately speaking) has the same user acceptance problem. Usable as a location map? [ edit ] Yes: there is no distortion north-south or east-west.
Version 4:Equidistant cylindrical map stretched 150% vertically [ edit ] Version 4. Who did it? [ edit ] Me derived from an equidistant cylindrical map produced from public domain map engine at http://www.aquarius.geomar.de/omc/ and User:SFC9394 's original What's the projection? [ edit ] Equidistant cylindrical from -8W to 0E, 54.5N to 61N, stretched 150% north-south. What's the problem with it? [ edit ] In terms of projection, probably none (see below). In terms of user acceptance, this will probably be acceptable. Usable as a location map? [ edit ] Yes: there is no distortion east-west. The 150% distortion north-south is constant (unlike Mercator, where the distortion varies) and so will probably be coped with by Template:location map
