A few of us have been refining our thinking and description of the web-mapping misalignment problem. Scott from the OGC has noted the importance of this topic and invited us to raise the topics at the next OGC Technical Committee meeting at Banff (9 Sept).

When providing WGS84 locations, how would I know which WGS84 variant is being supplied? Is the receiver involved in this? Or is it the satellites that control this? Is it enough to know the date of the measurement? Or must one track more to know which WGS84 variant is provided? -- Roger Oberholtzer _______________________________________________ PROJ mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/proj
