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

[noah ahles]

Hi All,

A 7.8 magnitude earthquake devastated the coastal region of Ecuador on
Saturday, April 16th. This major event was followed by several aftershocks
and has caused significant loss of life and damage to infrastructure (
http://edition.cnn.com/2016/04/18/americas/ecuador-earthquake/index.html).

Join us to create digital maps of the most affected areas, providing rescue
operations with valuable information to save lives and distribute supplies
to those in need.

*Where: Aiken Center, UVM Campus - Computer Lab, Room 101*
*When: Wednesday April 20th, 6pm - 9pm*

Here is the event page for the event: http://tinyurl.com/jjo7lu5

The most vulnerable people are those in rural areas, which are the hardest
to reach due to roadways that have been destroyed. Having an up-to-date map
of the area is crucial to helping as many people as possible as quickly as
possible.

Anyone can join, even if you have no experience. There will be computers
provided but you can bring a laptop if you'd like. Feel free to tell some
friends and stop by for as long as you have time for. There will be pizza!

This is the most time sensitive project we have worked on all semester.
Even if you have only a half hour to stop by it will go a long way. If you
would like to work on the project remotely, there are instructions on how
to get going at the bottom of the page. We will be using the hashtag
#MapEcuador to track our edits. Send me an email if you have any questions.

When thousands of people around the world contribute to mapping areas
together we can rapidly produce actionable datasets when they are needed
most.

Best,
Noah

OpenStreetMap Instructions

   -

   Start by making an account using FireFox or Google Chrome:
   http://www.openstreetmap.org/ and make sure to check the allow public
   domain button
   -

   Zoom in somewhere and press the edit button in the upper left corner
   -

   Start the Walkthrough, (the walkthrough can also be accessed by clicking
   the help button on the right hand side of the screen)
   -

   Once you have done that head to the task manager and choose a task by
   searching for 'Ecuador'
   -

   http://tasks.hotosm.org/


   -

   Read the instructions carefully and then go to the contribute tab to
   sign out a tile, select the ID Editor from the drop down arrow, keep the
   instructions tab open to refer back to
   -

   Remember to save every 10 edits or so and use the changeset tag that is
   generated automatically and anything else that is requested in the
   Instructions tab e.g. source = Bing (this is found in the upper left corner
   after you press save)
   -

   Click, hold and drag the screen to pan around while editing
   -

   Click, hold and drag nodes on a feature to reshape it
   -

   When creating lines drag a node back into the previous node to delete a
   section
   -

   Control + Z and Control + Y work well for going back or forward
   respectively 1 edit (e.g. if you accidentally erase something hold Control
   + Z to bring it back)
   -

   Change brightness to 100% in "Background Settings" on the right of the
   ID editor, activating the minimap button may also be helpful for keeping
   track of where you are editing
   -

   When finishing up a tile (press ‘Stop Mapping’ if there is more to do in
   the tile or ‘Mark as Done’ if it is finished) it is a good habit to write a
   short comment about the features that you edited within that tile or if the
   imagery is missing a section, cloud cover etc.
   -

   If you forget to classify a feature and try to save it, there will be an
   error. Click on the error message to return to the untagged feature to
   classify it
   -

   Square buildings with the 'S' key after classifying them (create area,
   classify it as building, then press 's')
   -

   Make sure buildings do not overlap each other, zoom in very close if you
   think they may be touching
   -

   The 'W' key will turn data colors on and off so you can see under edits
   that have already been done
   -

   If you are just starting out, try not to delete data that others have
   created
   -

   Hotkeys for lines and areas are 2 and 3
   -

   If the imagery is offset, there is a 'fix alignment function' in
   background settings on the right of the screen
   -

   keep the Task manager INSTRUCTIONS tab open to refer back to whenever
   needed, this tab details how to classify features
   -

   If the tile is too big you can split it using the task manager
   - When creating road networks it's important that the roads are actually
   connecting to each other as it shows in the line segment of the
   walkthrough, try not to connect these road networks to other polygons (e.g.
   landuse = residential or administrative boundaries)
   - Add the hashtag #MapEcuador to the changeset comments that are
   automatically populated (after clicking save edits it is in the upper left
   hand corner of the screen)
