HGIS data of Greater London's Industry 1865-1875

<p>Based on the First Series of the Ordnance Survey London Town Plans. Each factory is coded to indicate whether it is on both or just one of the two 19th century series of Ordnance Survey London Town Plans. I have also tried to catagorize the factories. There are some other incomplete fields or fields used in earlier versions of this&nbsp;database.
