Lambeth's open data principles

Lambeth Council's Open Data principles are:

  • Lambeth will be open and transparent with all data by default, increasing the amount of Open Data published over time. For example this means if data would be released under a Freedom of Information (FOI) request then they can be published as open data on the council's web pages
  • Open Data will be published to the council's open data web pages under the terms of the Open Government License
  • All Open Data will be published in recognised accessible machine readable formats to enable re-use, for example CSV or JSON
  • Any data released openly will be aggregated to an appropriate level to ensure data protection and individual privacy
  • All Open Data that are published to the council's web pages will be accompanied by details of the source, the period of time that they cover and any other necessary information
  • Wherever possible data that are published to the Council's Open Data web pages will also be published to the London Data Store

What data do we release?

Lambeth Council maintains over 200 hundred regularly refreshed spatial datasets which we use to create maps and mapping tools.

We release all of the spatial datasets we has the right to and every dataset is freely available for reuse under the Open Government License.

Spatial datasets:

  • Contain X and Y coordinates in a recognised format that can be shown on a map
  • Have accompanying information about the dataset to help you understand it (such as what it contains, when it was produced)
  • Come in a standard format that can be combined with other datasets (.csv for point datasets; .JSON for polygon datasets)

Spatial datasets come in two types:

  • point datasets – these show a single point for a record (such as where a council office is), along with one X and one Y coordinate so it can plotted on a map. Point datasets are released in .csv format, which can be read by mapping software or opened in spreadsheet programmes like Microsoft Excel
  • polygon datasets – these contain the boundaries and extent of each record (such as how where and how big a park is). Each record will have hundreds of X and Y coordinates. Polygon datasets are released in .JSON format, which can only be read by mapping software such as QGIS, ArcGIS or MapInfo

 Open Data Institute accreditation

Lambeth Open Data has achieved a 'raw level' certificate from the Open Data Institute, which means this data makes a great start at the basics of publishing open data.
