First place I looked was where I knew the data was dodgy. There is no single good database of conservation areas held by NE as (unlike London, Wales and Scotalnd) as it shows no data where LPAs has refused to sign an Inspire directive sign off – and teh national map rather than showing np data shows no CAs. Similarly the data is not grouped by theme, has major gaps and doesnt filter, (fpor example former i.e. cut down ancient woodlands).
As a prototype this wouldn’t be worrying, but already it is being piloted for Plan X, the supposed online platform for applying for everything, first LDCs in Southwalk, so if rolled out for Windsor and Maidenhead for example it would be wrong wrong wrong. A huge data cleansing and checking process is necessary, for which a national geospatial agency should be responsible for, like in many other countries.
