Talk:Spatial reference system

Spatial referencing system

Shouldn't this be an article itself? While the grids are the end results without knowledge of how to build a grid that information is useless. I need that information or I'd fill it out here myself. Nickjost 21:25, 24 October 2006 (UTC)

Requested move

The following discussion is an archived discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the move request was: page moved. Appears uncontroversial, and required admin assistance only because of the two trivial versions in the page history of the target. Andrewa (talk) 19:01, 27 March 2011 (UTC)

Spatial referencing system → Spatial reference system — "Spatial reference system" is more commonly used, and is the wording used in the Simple feature access standards specification. +mt 07:44, 15 March 2011 (UTC)

Merge SRID

An SRID is simply an integer code that references a spatial reference system. I'll merge this over in the next week if there are no objections. +mt 10:09, 30 June 2011 (UTC)

For me, ok (remenber to manage the redirections of SRID and Spatial Reference System Identifier)... --Krauss (talk) 23:05, 30 July 2011 (UTC)

This is my vote, but there are pros and cons for register,

pros: all "very related" information in one article. It is very important in my view...

cons: SRID is a OGC Standard, and the SRID article have very technical information; Spatial reference system is a cartographic concept, that can be augmented with History section, like UTM History, and other more encyclopedic informations (like some about Horizontal position representation). A abstract for SRID may be more appropriate.

I completely agree with your concerns about the precedence with the OGC Standards and keeping all the technical details regarding history, schema, etc. +mt 05:36, 31 July 2011 (UTC)

Inter-page alignment

At Talk:Geographic coordinate system there is a discussion over how this page and Geographic coordinate system should be aligned to use a consistent terminology.Bplewe (talk) 00:44, 24 November 2021 (UTC)

So what do each of these co-ordinate systems look like?

I can see this one "FVV5+P2 London" used in google maps, but I have no idea which system it is using. Having a table that shows an example in one column and the name (as a link it its article) in the other would be great. 212.36.35.62 (talk) 12:27, 13 July 2022 (UTC)

ECEF latitude in relation to geographic latitude

Since the "ECEF latitude" isn't the same as the "geographic latitude" for a spheroid, as the image "Earth centered, Earth fixed coordinates in relation to latitude and longitude." might suggest. https://upload.wikimedia.org/wikipedia/commons/thumb/7/7b/ECEF.svg/580px-ECEF.svg.png

I would replace that image with this one, or at least make a reference to it, to make the difference clear: https://upload.wikimedia.org/wikipedia/commons/thumb/6/62/Ecef_coordinates.svg/660px-Ecef_coordinates.svg.png Plhbwiki (talk) 22:49, 22 December 2022 (UTC)

Vertical CRSes

The article as it stands is largely limited to horizontal CRSes (ellipsoid, horizontal datum, projection). There is a brief mention of vertical reference frames, however otherwise (including in the lede) the focus is on 2D only. Given vertical CRS and datums (e.g. EGM96) are now being considered in a much more integrated way, with full 3D CRS being part of EPSG (for instance EPSG:6649 = NAD83(CSRS) / UTM zone 18N + CGVD2013 (height)), we should probably reframe it as potentially full 3D with horizontal-only 2D as a subset.
