<br>
The original provincial boundaries were based on Namria's 1:250K<br>
topographic maps this is very coarse and useful only to provide an<br>
overview of the province. At larger scales (or higher zoom levels in<br>
webmapping parlance), this is very inaccurate.<br>
<br>
There is also a free dataset of administrative boundaries (from region<br>
to barangay) available at <a href="http://philgis.org" target="_blank">philgis.org</a> [0] which is also the same data<br>
from GADM [1]. Based on my personal/anecdotal discussions with<br>
several people, this data also came from NAMRIA. This is a very good<br>
dataset but we cannot import it in OSM due to the license issues at<br>
the same time, we also think that it is also inaccurate at the<br>
municipal and brgy level [2].<br>
<br>
You are of course welcome to use this data in conjunction with OSM's<br>
dataset to compose your maps in any GIS software.<br>
<br>
The best way to get administrative boundaries is to request these data<br>
to the concerned local government unit (provincial and municipality).<br>
We can easily import them once explicit permission is secured.<br>

PS. Glad to know western Mindanao is getting more OSM love. Keep on mapping!<br>
