[Hello everyone; this is my first post here, after lurking for a few weeks. Thanks to Phil Archer for the suggestion (blame him if you don't like what I have to say!). I've been involved in geocoding on the web for some years, not least in efforts to use and extend the Geo microformat, contributions to vCard 4.0/ rfc6350, and in adding geocoding to Wikipedia and its sister projects.] On 24 March 2017 at 05:08, Bruce Bannerman <bruce.bannerman@bom.gov.au> wrote: > I note the statement “(WGS 84) Coordinate Reference System is > used in almost all cases where spatial data is published on the > Web”. I find this statement dangerous +1 It certainly is not true for coordinates on other bodies, such as the Moon, Mars, etc. In such cases it is important to be able to specify the CRS, or at least the body (in which case a /default/ CRS should be commonly understood). Some notes on these issues (gathered by me circa 2006, and no longer maintained) may be found at: http://microformats.org/wiki/geo-extension-strawman and linked pages. > and very difficult to believe! It may, as Ed Parsons notes, be literally true - but that doesn't mean that "edge cases" such as I describe, which are nonetheless are huge in number, should be ignored. -- Andy Mabbett @pigsonthewing http://pigsonthewing.org.uk
