The following is a map of completed buildings in Hong Kong from 2005 to 2011, according to data from Buildings Department as processed by us (errors may occur): http://opengov.jmsc.hku.hk/datamap/#completed . It is still being worked on as we speak, so bugs might also be found.

Using a text processing tool on Linux, we extracted the text of every section 5.6 of Buildings Department’s PDF monthly digests (here’s one of the 80-something published between 2005 and 2011).

The data was cleaned with Google Refine to the best of our capacities, and mapped with Google Fusion Tables according to the town planning units. We couldn’t do with addresses were often messy, and those in the New Territories often referred to their lot number only.

There are still lots of semi-open data (because not originally in a raw text format) provided by the Hong Kong government that could use a bit of repackaging job. We’ll get back to you soon on this.
