Raster Layer getting cut off at antimeridian line (180/-180 longitude)

MattAshman96 — Mon, 22 Sep 2025 13:16:00 GMT

I have a georeferenced .tif file that cuts out at the antimeridian line - anything east of 180 longitude gets cut off. I am using an OpenSeaMap basemap with the WebMercator spatial reference.

If I don't use a basemap at all, and change to Wgs84 spatial reference, it still gets cut off but at 207 longitude.

The file I'm using should span from Australia to Chile (for some reason it would let me upload the .tif or examples of the issue to this post)

Would appreciate any tips on how to get the whole raster to display properly.

Hi Matt,

What's the value of MapView Property WrapAroundMode?

Thanks

In both cases (testing with WebMercator and Wgs84) the WrapAroundMode is 'EnabledWhenSupported' and IsWrapAroundEnabled is 'True'.

I've also noticed that more of the .TIF is shown at a higher scale (more zoomed out) - although still very cut off.

Seems to let me add images/files now so I've attached below:

The .TIF I'm using (zipped with the extra files)
example.png: showing it being cut off
zoomed out.png: showing more of the chart being displayed when zoomed out
zoomed in.png: showing more of the chart cut off when zoomed in

Thanks
