<p>They provide downloadable shape, KML and low resolution data
files. Someone could ask them to provide us with high resolution
data as they seemed to have done all the calculations according to
the UN regulations and International Standards. They used PostGIS
to produce it.<br>

<div> The Median Lines are defined in terms of the Baselines - a
simplified representation of the coastline doing specific things
around islands, bays and estuaries. Perhaps we can get hold of
the Baseline data and create our own median lines mathematically
from that? </div>

The Spanish law says that in the absence of an agreement
with another country, their territorial sea shall not extend
beyond the median line: <br>

Moroccan law also has the same arrangement: <br>

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>

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>
