Map Based Search

This new release of Map Based Search was commissioned by UK Location Programme and delivered in collaboration with Ordnance Survey and the Cabinet Office.


To help in the discovery of geographical data at, the UK Location Programme has provided a map based search tool which is providing a richer, more advanced way of searching, at national, regional and local level, for records of data sets and services that are referenced by geographical coordinates. . This is done by allowing the user to indicate their area of interest on a map and then to submit that as a search on the datasets’ bounding boxes which are held in their metadata records. We welcome feedback on the tool and contact details are given below.

Overview of Map Based Search functionality

The following section provides a high level overview of Map Based Search functionality which is described in further depth within the Map Based Search User Guide

  • The navigation controls can be used to locate the area of interest, in addition terms such as place name, postcode as well as longitude and latitude coordinates can be used. Coordinates should be in the format of a numerical string separated by a comma. For example: 51.49, -0.12.

  • Map based search will return location data records with geographic extents that fall completely within, completely envelop or cut across the search area box.

  • Search boxes will not be saved when the search is complete.

  • A standard key word search may also be used to filter the results of a map based search.

  • A search may not return any records until data sets are available.

  • The map projection is European Terrestrial Reference System developed in 1989 (ETRS89) providing a UK wide search extent and ensuring interoperability between datasets across the UK and Europe.

  • The map we have used includes territorial waters as marine data will also be available.

Points to note

When using the map zoom controls to zoom in or out, users of Internet Explorer may see parts of the map displayed in the wrong place on screen. If this happens, consider using an alternative browser or this work-around for IE version 10: click the Cog symbol in the top right -> “Internet Options” -> “Advanced” tab -> Uncheck “Disable script debugging (Internet Explorer)"


We welcome feedback on the current version of the Map Based Search as your comments and suggestions will be fed in to help us improve the tool.
