The source of these boundaries is a mystery. I tried to contact the mapper that added them several times but never received any reply. 

In some cases where alignment was extremely off (e.g. significant number of mapped barangays or schools within wrong municipality) I've removed them already. 

Left out the ones in Maguindanao because there aren't many mapped objects to confirm inaccuracy. 

Are only minor adjustments needed here or would it be preferable to remove the boundaries completely until reasonably accurate data is available?
