Hi David,

I saw a similar ifsar/insar import over Baybay City, which I removed
since it overlapped with existing coastline and riverbank polygons
traced in Bing. I'm curious who did this but I did not followed up
with the concerned mapper.  From what I remembered, PH gov acquired
ifsar data over Leyte after Typhoon Haiyan. I'm quite sure that the PH
gov did not give any permission to import them to OSM or its
derivatives. In addition, ifsar vectors were derived from hires raster
(~20m), so the staircase will be in a similar length.

Might be good to probe more.  Can you give me sample changesets so I
can ask around.
