Imagery

[imagery url available only after accepting the license]

Access to this imagery is limited by the NextView license agreement.

You need to review and acknowledge the agreement.


Download the NextView imagery to trace this task by enabling "Remote Control" in JOSM and clicking on the link (or setting up a custom layer in iD). You will need to accept the NextView License. Please understand the following:

This tiled map service (TMS) contains post-Typhoon Haiyan imagery over Tacloban City, Philippines, and is composed on two satellite images taken on November 9th (southern half) and 10th (northern half) 2013. The images are both from DigitalGlobe's WorldView-2 satellite, and they have been pan-sharpened to increase interpretability and ortho-rectified for terrain corrected geographic precision. No contrast stretch has been applied to the imagery. Collectively the two images are over 13GB in size

OSM WORKFLOW:

DO NOT delete items

INFLICTED HEAVY DAMAGE TO BUILDINGS, INFRASTRUCTURE AND AREAS

If objects appear OK, leave them be. Otherwise, use these tags :

For each damaged building

building=damaged + typhoon:damage=yes or building=collapsed + typhoon:damage=yes

Obstacle at a point on the road

barrier=debris + + typhoon:damage=yes

Road section

Please make a segment covering the damages and mark it: status=impassable + + typhoon:damage=yes

Areas of debris (house collapsed)

landuse=brownfield + typhoon:damage=yes

Do not attempt anything more creative at this time. We are aiming for a high-level overview and more complicated tags could introduce subjectivity into the process.

Also, please add the following source tag to the objects you modify based on the NextView imagery.

source=WorldView-2,DigitalGlobe,Nextview,2013/11/09
