[mapserver-users] Which north polar projection works best with MapServer?

[Passmore, James H.]

I've been trying to serve a BlueMarble tiff in MapServer that adds a backdrop to a North Polar projection, specifically epsg:3413.

I cut the standard BlueMarble tiff to the bounds extent of this projection as defined at: http://spatialreference.org/ref/epsg/3413/

I've tried to both to reproject this tiff to epsg:3413 from epsg:4326 (which produces some odd artefacts) and I've tried to serve the tiff natively as epsg:3413 (which doesn't seem to work at all).

I see there is an existing ticket "polar reprojection bug revisited" on github https://github.com/mapserver/mapserver/issues/2765 and I've added some screen dumps to it that best illustrate my issue.

Obviously MapServer seems to have issues with this projection, so my question is which projection(s) could I use to show the north polar region, without any artefacts?

Thanks
