This is a HOT activation in the Philippines
Tropical Storm Megi (Philippine Local name: Juan) is the first typhoon of 2010 in the Pacific Basin to achieve "Super Typhoon" status, and the first in the Western Pacific after Nida in 2009.[4] It is also the first tropical cyclone since Hurricane Wilma of the 2005 Atlantic hurricane season confirmed to have a pressure below 900 millibars. Megi was also the strongest storm thus far in the 2010 Pacific typhoon season, and thus far is the strongest tropical cyclone recorded worldwide in 2010, with a pressure of 885 hPa (mbar). It made landfall early on October 18 in northeastern Luzon at Sierra Madre becoming one of the strongest storms ever to make landfall anywhere in the world.

Mapping coordination
No imagery is available in the area, other than landsat.
Mapping priorities
- Large rivers and tributaries (use Landsat for rivers and 250K and 50K topo maps for river names)
- Move place=town/city node location to the town proper.
- Roads and bridges (visible roads in Landsat are most likely primary and secondary, unknown roads should be tagged as highway=roads)
- Hospital locations (an aid group is transporting medical supplies, but needs actual locations and contacts of hospitals in the area)
Map large rivers from Landsat
Track progress with OpenStreetBugs
- Use this to help find where there are largish rivers (hopefully visible in Landsat) which still need sketching in
- Label bugs as fixed if you have done a river, or if you find that somebody else has done it (osmarender layer is good for checking)
- Add new bugs. Currently Harry has layed a load of bugs around the Western mountain range, but not the Eastern one.

- Rectified 1:50 topo maps in WMS
The 1:50K topo maps are copyrighted to NAMRIA. Leonard Soriano manually scanned them and gave permission to OSM for tracing ( talk-ph thread ). Original scans are available below:

- To add a new WMS Server in JOSM, use the Menu: 'Edit' menu -> 'Preferences' and click on the WMS tab. Now you can add / remove WMS server URL's. Use either of the following WMS

- NOTES on using the maps: The topomaps are old (ca 1950s), much of the roads, trails, in some case even rivers and other features have changed since. This useful for tracing and naming natural features. The WMS are shifted in some areas, move the layer in JOSM, using the "Adjust the position of the WMS layer". Add the tag: source=1:50k NAMRIA topo maps.
- Georeferenced 1:250k topo maps

- Download the map and use http://maps.nypl.org/relief to rectify. Add tags ph_topo, hot and 250k.
- Post the link here and the wms.
- NOTES on using these maps: DON'T TRACE ROADS. The maps are old (ca 1950s), much of the roads, trails, in some case even rivers and other features have changed since. This can be useful for tracing and naming natural features.
