BNgeo is a tool that allows users to easily look up geographic and administrative area data for postcodes in Brighton & Hove. Users can paste in a list of postcodes and BNgeo will provide the output area (OA), lower layer super output area (LSOA), middle layer super output area (MSOA), and ward for each postcode. Results can be viewed online or saved in a CSV file for Excel. The tool draws on open data from Brighton & Hove City Council and could potentially be expanded to include additional mapping features and output formats.
