Data extraction tool tested for faster planning

The data extraction platform, known as Extract, is in early testing and is being developed by the government’s Incubator for Artificial Intelligence (I.AI). The generative AI tool will turn old planning documents into digital data in 40 seconds – drastically reducing the one-to-two hours it typically takes planners to access information.

Extract uses AI to ‘read’ planning documents and pull out useful information. First, it uses AI to understand the text, finding key details like permitted development rights, addresses and dates. Then, it identifies and extracts maps, using computer vision to trace boundaries and define specific areas. Finally, it uses geolocation techniques to place those areas accurately on a modern map. According to I.AI, by breaking down the task into these steps and using different AI tools for each, Extract can transform complex documents into structured, digital data that can be used for modern planning.

Technology secretary Peter Kyle said: “The UK’s planning system has been held back for too long by outdated paper documents, slow processes, making it nearly impossible for councils to make informed decisions quickly. 

“As part of our Plan for Change, we’re using the power of AI to transform sluggish systems so we can start to rebuild. With Extract, councils will have access to better quality data so they can move more quickly on planning decisions and get on with driving growth.

“Technology like this could be a vital step towards councils meeting targets to help build the 1.5 million new homes the country needs, all while updating and improving the planning system for the future.”

The final version of the platform could be made available to councils later this year.
