The ONSPD is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The ONSPD is issued quarterly. (File size - 234 MB)NOTE: The 2022 ONSPDs included an incorrect update of the ITL field with two LA changes in Northamptonshire. This error has been corrected from the February 2023 ONSPD.NOTE: There was an issue with the originally published file where some change orders yet to be included in OS Boundary-LineÔ (including The Cumbria (Structural Changes) Order 2022, The North Yorkshire (Structural Changes) Order 2022 and The Somerset (Structural Changes) Order 2022) were mistakenly implemented for terminated postcodes. Version 2 corrects this, so that ward codes E05014171–E05014393 are not yet included.

UK Postcode-Level Flood Risk Data

Risk Level, Suitability, and Geographic Coordinates

By GetTheData [source]

About this dataset

The underlying source material has been compiled from open datasets including 'Risk of Flooding from Rivers and Sea', 'Open Postcode Geo' - all held under licence in agreement with Crown copyright & Database right (2017) & Royal Mail copyright & Database right (2017). The methodology used would combine each one of these datasets points into polygons with first identifying each risk area then mapping out corresponding postcode points within them which then could be tracked for its related longitude, latitude easting and northing positions. Through this comprehensive process you could get a better understanding regarding what individual postcodes are within high & low level flooding areas as well as find out from the latest publication date - when was it last issued? Ultimately this profound dataset comes in handy for prevention or even planning purposes informing citizens how serious some situations could become during extreme weather events such as floods or major storms allowing them to estimate potential risks before disaster ensues!

How to use the dataset

In order to effectively use this dataset there are several key pieces of terminology that you should be familiar with:

• FID – a unique identifier number associated with each record in the database.
• Postcode – an alphanumeric code used to identify a specific geographic region within the country; consists of two parts: an outward code (e.g., RG4) and an inward code (e.g., 8DN).
• PROB_4BAND – The flood risk level based on four categories represented in this field assigned by location - High, Medium, Low or Very Low; or None if outside of a high-risk area
• SUITABILITY – The suitability rating determined by location; either suitable or not suitable for development based on constraints for building in a floodplain
• Publication Date(PUB DATE) - The date that this information was made publicly available

• Risk For Insurance SOP (Risk_For_Insurance_SOP) - A ranking system from 1-5 used as guidance only when offering advice before taking out insurance cover over certain property located in certain very extreme area

  You will also need to be aware of some mathematical values associated with each postcode:

  • Easting – An eastward grid coordinate reference point corresponding to determining latitude/ longitude coordinates at specified points along an arc created by measuring distances between two other known points

  • Northing– A northward grid coordinate reference forming part of a geographical survey’s grid system

    Finally, here is how you can get started working with this amazing dataset:

Research Ideas

• Creating a custom application that provides users with real-time flood risk and safety advice based on postcode.
• Developing a map-based interface that integrates flood risk levels directly into Google Maps to assist people in planning trips and relocating in safer areas.
• Developing an app that tracks the geographically accurate position of every property within each postcode, allowing for better risk assessment for businesses and insurers

This dataset includes a series of modified UK administrative boundary shapefiles based on the 2011 census which are intended for use in more accurate visualisation of UK geospatial data analysis. There are two key features of these shapefiles: (1) administrative shapes have been clipped to the Ordnance Survey buildings shapefile, so that in choropleth visualisations relating to demographic data filled spaces represent populated areas of the UK rather than large undifferentiated blocks. (2) Shapefiles have been simplified to reduce loading and processing time, in the case of this repository at 100m. After testing, we have settled on a procedure to render buildings layer visually comprehensible at high zoom levels, by adding a small buffer, dissolving (so that individual overlapping shapes combine into a single more easily visualised shape) and then simplifying at 150m. It is important to emphasise that because of the use of simplification (using a Ramer–Douglas–Peucker algorithm), these shapefiles are not suitable for analysis as boundaries may not be suitably precise or accurate. For users interested in the process used to generate these files you can consult the codebase deposited on github.

Many thanks to colleagues including Alasdair Rae for recommendations on technique used here. Computations were performed using the University of Birmingham's BEAR Cloud service, which provides flexible resource for intensive computational work to the University's research community. See http://www.birmingham.ac.uk/bear for more details. Given the massive size of datasets involved (including the district buildings vector shapefile which is 1.4gb and consists of hundreds of thousands of individual shapes), this work would have been impossible without this invaluable resource. I hope that these files will be of use to colleagues who may not have access to similar large computational arrays and make the process of visualising UK boundary and census data more accurate and efficient.

require(sf) # load simplefeature data class, supercedes sp() and used for st_read

given the size and complexity even of simplified files here, ragg is highly recommended

for users on macos given inefficiencies in default R graphics device

require(ragg)

create paths as needed

if (dir.exists("data") == FALSE) { dir.create("data") }

download data files only if they aren't already present

if (file.exists("data/infuse_dist_lyr_2011.shp") == FALSE) { download.file("https://borders.ukdataservice.ac.uk/ukborders/easy_download/prebuilt/shape/infuse_dist_lyr_2011.zip", destfile = "data/infuse_dist_lyr_2011.zip") unzip("infuse_dist_lyr_2011.zip", exdir = "data")} local_authorities <- st_read("data/infuse_dist_lyr_2011.shp")

This data set is a collection of estimated daily mean and maximum values for a range of air quality and meterological measurements and model forecasts for the UK and crown dependencies postcode districts (e.g. 'AB') for the years 2016-2019, inclusive.

The paper describing this dataset is available here: https://www.nature.com/articles/s41597-022-01135-6

The data uses a 'concentric regions' method to estimate the measurement for all regions, as follows. If measurements exist within the region, the mean of those measurements is used, if not, then a ring of neighbouring postcode regions are selected, and the mean of their measurement values used. If no measurement sites/data are found in the first ring, the process continues, taking the next ring of postcode district regions, working outwards until one or more sensors are found in a ring. As well as the measurement estimations, the number of rings required to find site data and make the estimations is also published. As a result, please note that estimations with higher ring counts ('rings') are likely to be calculated from more distant sensors. This distance depends upon the size of the postcode regions surrounding the location being estimated. Please use the ring count ('rings') to limit/filter estimations based on your required level of confidence.

The meteorological, pollen and air quality measurement data used to make the regional estimations can be found at this Zenodo archive. The data there contains Temperature, Relative Humidity, and Pressure data, downloaded from the Met Office MIDAS archives via the MEDMI server (https://www.data-mashup.org.uk/). Also downloaded from the MEDMI server are daily pollen measurements for the UK. PM10, PM2.5, NO2, NOx (as NO2), O3, and SO2 measurements from the DEFRA AURN network, and also model forecasts of the same made using the EMEP model.

The code used to make the estimations is available at this Zenodo archive.

The postcode data in postcode_district_data.csv are collated from several sources:

https://www.doogal.co.uk/UKPostcodes.php (population figures for the UK (UK Census 2011))

https://www.freemaptools.com/download-uk-postcode-outcode-boundaries.htm (postcode boundary polygons for UK and crown dependancies)

https://www.gov.im/media/1369690/isle-of-man-in-numbers-july-2020.pdf (Isle of Man (IM) population data for April 2016)

The data-set is presented in CSV format, as six files:

postcode_district_data.csv: location metadata (region_id, geometry, description, population, country)

regional_site_counts.csv: a table showing the number of sites for each measurement (columns), for each region_id (rows). region_id's match those in the postcode_district_data.csv file.

turing_regional_estimates_aq_daily_met_pollen_pollution_imputed_data.csv: uses imputed site data (timestamp, region_id, ...[measurement name, rings]) ('rings' is the number of rings required to make the estimation)

turing_regional_estimates_aq_daily_met_pollen_pollution_original_data.csv: uses original site data (timestamp, region_id, ...[measurement name, rings]) ('rings' is the number of rings required to make the estimation)

turing_regional_estimates_aq_loc_type_daily_imputed_data.csv: uses imputed site data. Air quality regional estimates are calculated using specific AQ site location types* separately. (To prevent, for example, 'Traffic Urban' type sites being used to estimate 'non-traffic' or rural regions.)

turing_regional_estimates_aq_loc_type_daily_original_data.csv: uses original data. Air quality regional estimates are calculated using specific AQ site location types* separately. (To prevent, for example, 'Traffic Urban' type sites being used to estimate 'non-traffic' or rural regions.)

• Air quality site types:

Industrial: comprises 'urban industrial' (9 sites) and suburban industrial (2 sites)

'Rural background' (14 sites)

'Urban background' (48 sites)

'Urban traffic' (47 sites)
