[HOT] Emergency Mapathon in Burlington, VT - Ecuador Earthquake

[john whelan]

There has been much discussion about mapping buildings recently in HOT and
the Ecuador projects are for the most part buildings.

If you are supplying machines then please install JOSM with the
building_tool plugin which also implies JAVA.  Mapping with the JOSM
building_tool is fast and accurate, the validators will love you.

Mapping with a mouse is much more accurate so if possible have some spares.

If you're mapping in JOSM with the building tool just power it up, grab a
tile and split it, then split it again, edit with JOSM and show them how to
map the first building.  That's about all the training they need apart from
the up arrow on the top left to upload.

My personal advice is if you're mapping with iD split the tiles twice
again, if you have someone with JOSM around don't square in iD it doesn't
always work get the JOSM person to go into the tile, search <Crtl>f
building nodes:-7 then press q and upload the changes.  You might want to
have the mappers inspect the squared buildings afterwards.

If you are mapping with iD roughly every hour save and press the stop
mapping button.  Then select the tile again, this appears to be important
as I see duplicate buildings from different mappers and it is suspected the
first mapper times out and a second mapper grabs the tile so two mappers
are mapping the same area at the same time.

If you have any experienced mappers available then get them to read this
bit on validating.
http://wiki.openstreetmap.org/wiki/OSM_Tasking_Manager/Validating_data and
if they can validate as people map and give feedback that improves the
quality enormously.

learnosm.org is a very useful resource.  The training guides have been much
improved over the last little while.

Have fun.
