Since 1999, the SkyscraperPage Forum has been one of the most active skyscraper enthusiast communities on the web. The global membership discusses development news and construction activity on projects from around the world, alongside discussions on urban design, architecture, transportation and many other topics. SkyscraperPage.com also features unique skyscraper diagrams, a database of construction activity, and publishes popular skyscraper posters.
Here are skyscraper development maps for many cities.
If anyone can post updated information on projects to be added to the maps it would be most appriciated. Thanks! Particularly the locations of any projects that aren't already marked. Many projects are already in the SSP database but we don't know the locations of the yet.
