Historic parks in England, 1890s-1900s

Corrections Examples - showing historic parks to include and exclude

Due to the automated processes used to extract the historic parks layer, some revisions are still needed. We are inviting volunteers to easily record corrections they spot in the viewer.

Following the initial image detection work to identify stipple (indicating parkland), the following rules were applied to generalise / simplify the parkland layer:

• The minimum area to be shown as parkland is 0.1 hectares / 1,000 ²
• For non-parkland areas within parkland (ie. areas without stipple within a broader area of stipple), the maximum size of these non-parkland areas is 1 hectare
• Parkland areas that are 10 metres away from each other or less are blended together

The following examples illustrate these rules and provide more details on the types of parkland to be noted in the Correction Panel for inclusion or exclusion, as well as parkland to be ignored (ie. not noted in the Corrections Panel).

Missed parkland to add

= Parkland represented by black dots (stipple), which is more than 1 hectare / 10,000 metres² in extent. You can measure areas with our Measurement Tools to check they are larger than 1 hectare / 10,000 metres²

Parkland which has been wrongly included

= Parkland which has been wrongly included (eg. inter-tidal mud), or other dots and marks on the original map which are not part of the 'parkland' stipple.

Areas which should be ignored

= Areas which should be ignored as they don’t follow our definition of parkland:

• parkland with an extent of less than 1 hectare / 10,000 metres²
  

  This triangular-shaped area with parkland stipple (which has been excluded
  from the Zulu parkland layer) should be ignored as it is less than 1 hectare in extent.
• non-parkland areas within parkland with an extent of less than 1 hectare / 10,000 metres²
  

  This oval-shaped area without parkland stipple within a wider parkland area is wongly shown as
  parkland in the Zulu layer, but is less than 1 hectare in extent and so should be ignored.
• non-parkland areas (eg. paths, tracks, rivers/streams, etc.) within parkland with a width of 10 metres or less
  

  These roads and tracks through parkland are all less than 10 metres wide and so should be ignored.
