The map is powered by HDB Blocks Database, an Excel file compiled by me that took about 500 hours of manual work.
Map made originally in September 2017 using Google Fusion Tables, a FREE experimental application that provided only 9 colors of colored dots, as well as other icons representing various businesses. Google announced closure of Fusion Tables on 3 December 2019.
In October 2019 I moved to ZeeMaps, a paid service that provide 31 colors to choose from, and ability to filter and display only blocks of specific criteria. If anyone thinks that is better to use different colors that indicate block types and construction years, please tell.

Please report possible errors on map! (some blocks may have wrong floor plans, being added from my personal research).
