How to use the maps on Gwulo

To learn how to use Gwulo's maps, please watch this short video, or follow the instructions below.

When looking at a map such as the map of all Places, you can:

Zoom in:

• Click the '+' in the top-left corner, or
• Use your mouse-wheel, or
• Stretch two fingers apart on a touch screen

Zoom out:

• Click the '-' in the top-left corner, or
• Use your mouse-wheel, or
• Pinch two fingers together on a touch screen

Go full-screen:

• Click the [ ] icon in the top-right corner of the map.
• When you've finished, click the icon again or press the 'Esc' key on your keyboard.

View different layers:

• Click the layers icon on the right of the map. Click a layer to toggle it between hidden and shown.

View Places:

• Each marker is a Place in Hong Kong that has a page on Gwulo.
• The colour of the marker shows the current condition of that Place:
  • Green=In use,
  • Yellow=Ruin,
  • Red=Demolished,
  • Blue/White=Unknown.
• Click any marker and a pop-up appears to show the name of the Place. Click on the name to see photos and further details of that Place.

Groups of Places:

• The larger circles with numbers show groups of Places. The number shows how many Places are there. You can either zoom in to see them individually, or click the number to expand it.

More about the layers:

• When you click the layers icon, you see two lists of maps:
  • Base maps
