Changeset Comment

#osmgeoweek2017 #bc2020

When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".

Imagery

Please use the Bing aerial imagery

If the imagery seems to be out of alignment with existing roads and buildings, you should apply a shift on the imagery. In the iD editor: from the menu “Background settings” (shortcut, “B” key), choose “Adjust imagery offset.” Adjust the image visually.

Buildings

• Find a building on the satellite imagery and trace it with the "Area" tool
• Label the area as “Building” (building=yes), then correct for right angles by pressing the “S” key on your keyboard
• Please map all the buildings you can see within the square that you choose; if you leave some buildings unmapped do not mark the square as "Mark Task as Done"
• Avoid having building polygons touch each other

If you cannot complete the square, click "Stop mapping" and write a comment about your contributions (e.g., mapped buildings with Bing imagery) and any issues that arised (e.g., too much tree coverage to map all buildings)

Once you have completed a square, click "Mark Task as Done" and write a comment about your contributions (e.g., mapped buildings with Bing imagery)

Start Mapping!

• Click the "Start contributing" button below
• Find a square (i.e. a task)
• Click the "Start mapping" button to lock the square. If the square is too big, you can split it with the "Split" button
• Click "Edit with iD editor", you will be directed to a new tab where you can map out the features on iD
• Remember:
  • If you cannot complete the square, click "Stop mapping" and write a comment about your contributions (e.g., mapped buildings with Bing imagery) and any issues that arised (e.g., too much tree coverage to map all buildings)
  • Once you have completed a square, click "Mark task as done" and write a comment about your contributions (e.g., mapped buildings with Bing imagery)
