Since issue 100 of the new series of Newsletter there has been a regular item “Observations and Discoveries”. This is a collection of small articles about mining related sites in our region. Adam Russell has transcribed an index to the entries into a spreadsheet which Rob has converted to a database.
The database was then made available on the new (2017) web site. As the file included Ordnance Survey Grid References for the sites Rob converted those to Longitude/Latitude coordinates and linked the individual entries to OS1:50k mapping and the Longitude/Latitude coordinates link to Google maps.
A further development (2018) was to aggregate all the locations onto a single Google Map and then to a single OS map with clickable links to show more detail of the individual locations. Logged in members will see links below from this page to the database and the Google and OS aggregate maps.
