Thank you Blake and greetings everyone,

I'll just quickly jump in to say we are Activating to fulfill some requests for basemaps of the area impacted by 
Cyclone Gita (so far a few islands in the nation of Tonga) and potentially areas in South America having major flooding over the past couple weeks.

Tonga is actually really well mapped, mostly by just a few local mappers, and HOT was part of a project to capture UAV imagery recently, so it will mostly be advanced mapping to update and fill gaps.  The area affected by the flooding in South America is very large, so we're working with our partners to identify what exactly the need to determine the most effective use of the HOT community's time.  I'm also talking with the local community about what they think would be most beneficial projects to do. So far looks like buildings are the biggest data gap.

Stay tuned here, the tasking manager and/or slack...

Dear friends,

We have an urgent need to update the mapping in parts of Tonga.

We have updated UAV imagery for about 1/2 of Nuku'lofa island, the main island in the Tonga group.

This project is to add any missing buildings or otherwise improve the building footprints. Due to the importance of the project and need to adjust imagery and make judgements on existing mapping, it is Experienced mappers only.


We very much need your help if you can contribute to this project please.

Only listed as medium because it is limited to experienced mappers only, it is actually Urgent.

Special thank you to Nate, Cristiano and the World Bank for capturing and making the imagery available.
