<p>They provide downloadable shape, KML and low resolution data

As there is no agreement between the two countries it
would appear that they both think the boundary is the
median line. However Morocco amended their law last
year: <br>

Details in English are sparse (they haven't sent the
required paper work to the UN yet), but the changes
appear to be about their Atlantic maritime boundaries. <br>

Thanks Andrew. <br>
<br>
I was waiting here just in case anyone posted another
point of view, and no-one has. Unfortunately the US
document (which describes the Spanish point of view) says
"The Kingdom of Spain also includes its exclaves located
on the northern coast of Africa, which are beyond the
scope of this study". It does, however, describe what
Spain does elsewhere, which is presumably a "general
intent". As you say, the Moroccan article 2 ("In the
absence of a specific agreement on the subject, the
breadth of the territorial waters shall not extend beyond
a median line every point of which is equidistant from the
nearest points on the baselines of the Moroccan or
adjacent coasts") is clearer. <br>
<br>
Does anyone see a problem with the "median line" approach?
<br>
<br>
If not, does anyone fancy volunteering to actually make
the change? It'd need to be someone familiar with
boundary editing, which probably means familiarity with
JOSM's "validator" to check that the resulting boundaries
are both valid multipolygons and match the documentation
above. If not, I can do it, but it might take a bit
longer. <br>
<br>
