For SERS hunters: only (some of) brown and red blocks (pre-1980) may be selected for redevelopment, do not click other colors. There are only 13 different pieces on text under SERS prediction. See also list of potential SERS sites.

Filter blocks on map: click the magnifier in upper-right > choose Breakdown > contains > type “executive” > press enter : the map will show only blocks that contain executive apartments or maisonettes (you may need to increase maximum search results). In similar way you can filter blocks taller than # floors, blocks that underwent specific upgrading programmes, and so on.

Map made in October 2019 using ZeeMaps which provide 31 colors to choose from. If anyone thinks that is better to use different colors that indicate block types and construction years, please tell.
