Improved London Infrastructure Mapping Application launched

A second phase of the London Infrastructure Mapping Application (IMA) has been launched, writes James Robertson. The IMA is a free online tool that displays infrastructure and development data from a range of sources in an easy to use map that can be filtered based on the interests of users.

Users create their own bespoke map by using ‘layers’ on different types of infrastructure projects -  such as development, transport and utility projects - to display different results.  Users can further refine the results by cost, funding or planning status (such as projects with secured funding and approved plans), data source, or a specific location. Individual projects can then be selected to find out more information.

Users can also use ‘overlays’ to add further context to results. These include opportunity areas, housing zones, air quality ratings, broadband ‘not spots’ and even accessibility to public transport.  Overlays allow users to analyse projects or particular areas against a range of planning policies and research.

The updated version allows users to download data from their map results for use in other GIS tools.  Users can also import external data to the IMA, allowing for further personalised maps. 

One aim of the mapping tool is to encourage infrastructure providers - including engineers, contractors and developers - to work together in order to plan better and save resources. 

Jules Pipe, deputy mayor for planning, regeneration and skills, said: “Through this application, we have been able to bring data from across a wide range of sectors so that infrastructure providers have at their fingertips everything they may need to know about how the city will grow, and can take decisions accordingly.”

The IMA is currently available in two versions, a public interface available to all users and a private version with additional datasets accessible through registration with the Greater London Authority. 

The public version is now available at
