A website has mapped the history of land reclamation in Hong Kong since 1840, serving as an online “geodatabase” that aims to provide “spatial, temporal and historic context” to Hong Kong’s numerous, massive land reclamation projects.
According to the website, the mapping application uses geographic data and historic photos to visualise and document Hong Kong’s ever-changing coastline.

Users can use the time slider feature to view land reclamation projects from a certain time period and use the layers feature to turn on or off the three available overlays: original coastline, reclamation and historic photos.

The interactive map was developed by Vivian Ngo, a Hong Kong-born architect currently based in Los Angeles, as a part of her research on the impact of land reclamation on the coastline of Hong Kong.
