Access to Greenspace Indicator Fliss Rollings & Shona Nicol (GI-SAT), Scottish Government

Access to Greenspace Indicator: 1. Overview 2. Review and suitability of current method 3. Updates

Overview of Indicator • Produce a new national indicator on “improving access to Greenspace” • Using GIS to give an objective measure for each data zone • The percentage of households within a 5 minute walk of open Greenspace

OS Open Greenspace Data • Public park or garden • Play space • Playing field • Golf course • Tennis courts • Bowling green • Other Sports Facility • Allotments or Community Growing Spaces • Religious Ground • Cemetery

OS MasterMap Greenspace data Function Form • Public Park or Garden • Open Semi-Natural Private Garden • School Grounds • Inland Water Playing Field • Institutional Grounds • Other Sports Facility Woodland • • Golf Course Tennis Court Beach Or Foreshore • Amenity – Residential or • Play Space Manmade Surface Business • Bowling Green • Amenity – Transport Multi Surface • Land Use Changing • Camping or Caravan Park • Natural • Religious Grounds • Cemetery • Allotments or Community Growing Spaces

Methodology • Step 1: Preparing Greenspace data – Filtering OS MasterMap Greenspace classes – Generating access points 80m apart (some from OS Open product) – Removing Greenspace < 0.2 Ha • Not all classes are in the OS Open product so not at a national scale

Methodology • Step 2: – OS MasterMap Greenspace covers only settlements plus 500m – Data zones do not fit perfectly within these boundaries – Look at % fit between data zones and settlements to decide

Best Fit: Data Zones

Methodology • Step 3: Network analysis – Define area within 5 minutes (400m) of each Greenspace access points – Find the households within these areas – Match these households up with data zones – Find the percentage of households within each data zone within 5 minutes of GreenSpace

Example - Perth

Methodology Review • Results showed that 96% of households in the Data Zones within Settlements are within 400m from Greenspace. • This figure is not consistent with the Scottish Household Survey (SHS) outputs. • For SHS in 2015, 67 per cent of adults reported living within a 5 minute walk of their nearest Greenspace.

Suitability of methodology • The current methodology would not be suitable as a national indicator: – Use only Open data categories. Are MasterMap data categories relevant? – Ask OS to add relevant classes for the indicator from MasterMap to Open dataset. Could they? – Use other data sources i.e. National Forest Inventory & Bathing Waters • Timings to replace the current SHS measure

Update on Methodology • The ‘Amenity’ class contains incorrectly classified features, which are not useable Greenspace - area threshold increased • Adding the extra categories of ‘Natural - Beaches and Foreshores’ and ‘Natural - Inland Water’ to match SHS definition • Reducing the number Access Points to matching OS Open product average
