TMS WorldMercatorWGS84Quad.json issues #6

Closed jerstlouis closed 3 years ago

in http://schemas.opengis.net/tms/1.0/json/examples/WorldMercatorWGS84Quad.json

  1. In addition to "tileHeight" : where there should be "tileMatrices" : (also, other VTP2 participants currently have tileMatrix, but I believe we had previously agreed this should be plural), the topLeftCorner for each level should be e.g.

    [ -20037508.3427892439067, 20037508.3427892439067 ]

rather than

[-180, 90],

(as it is in WebMercatorQuad, another projected CRS tiling scheme).

  1. Also, the scales and the matrixWidth are all off by a factor of 2.

@jerstlouis Thanks for reporting this issue. The source of the issue is the OGC Two Dimensional Tile Matrix Set standard (OGC 17-083r2). Therefore the issue should be recorded on the OGC Standards Tracker, from where the "OGC 17-083r2" can be referenced. Please post it there.

@ghobona @joanma747 I was under the impression that OGC Standards Tracker was more or less effectively abandoned in favor of GitHub issues, and that the Tiles API SWG was taking on the responsibility to maintain the TileMatrixSet standard (maybe something to clarify in the new charter). There are multiple TMS issues currently reported here, and I fear that closing them here will get them forgotten in the standard tracker, while they are really something we should be tackling ASAP in the SWG meetings.

@jerstlouis

The Standards Tracker is still operational. The Standards Tracker is relevant for all published standards as it is a single place for anyone to lodge change requests.

As the TMS standard does not have its own Git repo, please log issues relating to the TMS standard on the Standards Tracker. The TMS standard will not be forgotten, the SWG just needs to find time to address the issues relating to the 2D TMS. I expect that it will be possible once the Tiles and Maps APIs go for Public Comment.

Please provide a Standards Tracker URI
