Why these borders?

Hi there, I was asked to find out what country borders you are using for the EO Dashboard basemap - and why you chose some that extend beyond the land area of the countries. Are these Exclusive Economic Zones?

Looking at, e.g. https://eodashboard.org/explore?x=-6929655.00275&y=-3452263.94443&z=3.35614&search=World%3A+Ocean+Primary+Productivity+%28MODIS%29&indicator=N1_NO2_diff_monthly

I see you are using a layer called overlay_base_bright_3857, e.g. https://s2maps-tiles.eu/wmts/1.0.0/overlay_base_bright_3857/default/g/2/2/1.jpg, and this info from your map tiles service https://s2maps-tiles.eu/wmts/1.0.0/WMTSCapabilities.xml

I guess this is not an issue, folks were just curious.

Hi Jonas,
I agree that these borders on some of VEDA renderings without transparency are odd. We've had this point raised by the Atmosphere theme scientists a very long time ago as well but to no conclusion on s2maps side yet #1504 (updating the maps infrastructure was not a heavy priority).

Coming back to your question, yes, it shows administrative borders including Exclusive Economic Zones.
