Hi, My concern was if the accuracy of conversions is good enough in WGS 84 system because one meter jumps around the North pole have quite big effect on Lon coordinates and quite small effect on Lat coordinates.

We’re only adding convenience, not removing any features regarding projections. Andreas.

At time 16:35 there is a slide that states “Use only geographic coordinates (WGS 84) in the API”. I wonder if such change would make it difficult to work with the Polar coordinate systems like those used in the Arctic SDI geoportal https://geoportal.arctic-sdi.org/ (press the World icon under the scale slider for selecting your favourite). Do we need to be worried? Jukka Rahkonen National Land Survey of Finland
