The online mapping of mines as an overlay on Google maps is now working again. This is the third time that we have had to mend this as Google has kept making changes to its mapping service. Hopefully things should be stable from now on.
New updated data sets have been released and these now use small red markers. Unfortunately at the moment the Coal and Non-ferrous data sets for England are not working, we are looking into the cause and will get these online as soon as possible. For the time being the previous data sets have been used; these have the larger back circles as markers.
