I am looking for vector data outlining the agricultural field boundaries in the UK (Specifically Scotland, England and Wales). I have tried all sources of open source data I can find and looked at Ordnance Survey Data.
Ordnance Survey have the data however they package it as part of the Vectormap Local data which costs in excess of £800k for the UK. The actual sub layer is called Rural Boundaries when the Shapefile is extracted.
If there is no realistic way of getting this data, or purchasing it for a reasonable price, is there a way to extract the data from aerial photography?
