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

• 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

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
