AlbertKa (<a class="moz-txt-link-freetext" href="http://www.openstreetmap.org/user/AlbertKa">http://www.openstreetmap.org/user/AlbertKa</a>) ha hecho un
buen trabajo trazando el bosque a base de la imágen satelital. Los
datos corresponden a Bing. Por lo tanto no debe haber sido una
importación, sino un trabajo manual. Los limites rectos se dan por
que no ahí terminó una o la otra tarea del Tasking Manager.<br>

<p dir="ltr">There are a few possible reasons for symmetrical
edits on such scale :</p>
<p dir="ltr">1) The shapes reflect a physical reality on the
ground <br>
= Not the case here. </p>
<p dir="ltr">2) The data available that has been used for mapping
the area is limited in a geometrically symmetric way and that
defines the mapping result. This can be due to at least <br>
2.1) Imported data shapes <br>
= Unlikely here unless there has, in fact, been an import (that
I just haven't heard of). So, possible but I'm assuming that
this is not the case here. <br>
2.2) For map data created with imagery (like it seems is quite
possibly the case here) the imagery used has limits (such as
high resolution bounds) that then have limited the mapping
outcome. <br>
= This seems like a plausible reason here (without looking at
the edit history of the data in question). </p>
<p dir="ltr">Finally, <br>
3) The area has been mapped using some sort of geographically
sliced (=restricted) mapping (coordination) tool. <br>
=> As I have set up at least one HOT Tasking Manager job for
this area (which is visible for the whole world, BTW) and as the
task has also been shared here and at Bilwi (when Felix and
Porfirio were there with Unicef) it's really quite possible that
this is the story behind this data. </p>
<p dir="ltr">It's of course also possible that the reason is a
combination of the above - or something else. </p>
<p dir="ltr">Perhaps the best way to try to figure the real story
behind any edits is to check out the history of the data in
question [1] and to contact (at least some of) the mapper(s) who
have created the data in question. </p>

<p dir="ltr">[1] Checking the history of data is easiest in JOSM.
Just download data for an area. Select an object you want to
research the history of and then simply hit Ctrl+H (as in
History). You'll get a popup window with the full history of the
object. The default tab shows the edit history of the tags of
the object and the other tab shows the nodes that have been part
of the object (if its a way=line object). To visualize things
you need to use a service that does it. I can look one up if
someone is interested. </p>
