Task recommended for JOSM users only

Before you begin mapping, Please review the Nepal Earthquake - IDP Collection Guidance. This guide provides examples and explanations to consistently collect IDPs among various tasks.

After the main earthquake many buildings are damaged and weakened and can easily be collapsed by aftershocks. For this reason, it is common for people to sleep outside in tent cities in open areas of the city (soccer fields, school yards, etc).

The purpose of this task is to map these tent city locations to help responders on the ground supply them with food, water, and medical care as needed. It also helps assessment teams get a sense of how many people are in need of aid and have lost houses.

Imagery

tms[22]:https://{switch:a,b,c,d}.tiles.mapbox.com/v4/mapbox.satellite-kathmandu-20150425-after/{zoom}/{x}/{y}.jpg?access_token=pk.eyJ1Ijoib3BlbnN0cmVldG1hcCIsImEiOiJhNVlHd29ZIn0.ti6wATGDWOmCnCYen-Ip7Q


For this task it is recommended to use JOSM so you can easily switch back and forth between the pre-event Bing imagery and the post-event WorldView imagery.

Scan through your task square very carefully, it is important that we find them all, even very small ones. For each campsite you find, draw an area around the entire campsite and tag it with the following tags:

  • idp:camp_site=spontaneous_camp
  • damage:event=nepal_earthquake_2015
  • source=DigitalGlobe/Mapbox WV3 27 April 2015

PLEASE reference the Nepal Earthquake - IDP Collection Guidance

The best procedure to follow is to scan through the Worldview image until you think you have found a campsite, and then switch to the Bing imagery to see it before the quake and determine its status.

You can easily show or hide imagery layers in JOSM by pressing alt+NUMBER, where NUMBER is the number of the layer, starting with 1 at the bottom of the list and counting up from there, so alt+3 will show/hide the third layer from the bottom.
