- Abstract
- This width data has been created in GIS using OS Master Map as its base. It contains road and pavement widths in 5m intervals county wide. The data was created in 2022
The sub layers Highway, Pavements and Paths can help inform decisions. We have kept the 3 layers separate and not merged them together. This is an advantage as not all physical barriers are shown on OS mapping. You may need to use your judgement to determine if there is a physical barrier between the 3 features.
THIS IS NOT A SUBSTITUTE FOR SITE BASED MEASUREMENTS!.
This data needs to be treated with the usual caveats and should be used as a guid only, site-based measurements will always be the most accurate.
For information about the accuracy of the OS Mastermap data you can access via the link below. https://www.ordnancesurvey.co.uk/business-government/tools-support/mastermap-topography-support however the Root Mean Square Error (RMSE*) is approximately 0.5m. *RMSE (root mean squared error) is the square root of the mean of the squares of the errors between the observations - Topic Category
