Re: The wiki now has a CRS page

Thanks a lot, Frans.

A couple of suggested edits (which I can take care of):


1. About section "WGS84" - quoting:

[[
WGS84, a CRS for latitude-longitude coordinates, is very popular on
the web. This has lead to the idea that this CRS can be considered a
default CRS. In fact, many specifications have done so (basic geo,
GeoJSON, geosparql).
]]

As you also say later in the wiki page, GeoJSON is not using lat-long
as the axis order, and GeoSPARQL is using CRS84. Instead, I would add
schema.org as one of the specification using WGS84 as default CRS.


2. The LOCADD wiki [1] may provide some useful material. E.g.,

- other CRS registers, as http://spatialreference.org/ and http://epsg.io/

- URLs operated by the OGC register for compound reference systems -
as http://www.opengis.net/def/crs-compound?1=http://www.opengis.net/def/crs/EPSG/0/4269&2=http://www.opengis.net/def/crs/EPSG/0/5713


My two cents

Andrea
