Geocode UK Postcodes & Identify Geographical Hierarchies

By GetTheData [source]

About this dataset

This Open Postcode Geo dataset contains a wealth of information about UK postcodes. For each postcode, there are several geospace attributes you can use to refine your analysis such as latitude, longitude, easting and northing. Moreover, the positional quality indicator provides a range of accuracy levels for each geospace attribute.

In addition to positioning data, this dataset has been derived from the Office for National Statistics' Postcode Directory which gives users extra insights into postcodes such as postcode areas, districts and sectors — enabling them to accurately group records into geographic hierarchies: perfect for mapping applications and statistical analysis!

And with data coming from multiple sources — The Crown Copyright & Database Right (2016), Royal Mail Copyright & Database Right (2016) & ONS ™ - users can be assured that Open Postcode Geo provides accurate and up-to-date results that cover terminated archives as well as smaller user-generated postcodes! All released under the UK Government's Open Government Licence v3; with attribution required pursuant to ONS Licences info... Now you too have access to powerful spatial information about the United Kingdom; helping you gain unparalleled insight in record time

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:

    1. Download it onto your computer from Kaggle's website (www.kaggle/datasets/UK Postecode Level Flood Risk Data).

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

A best-fit lookup between output areas and enumeration postcode sectors as at 31 May 2021 in England and Wales. The 2021 OA to enumeration postcode sector (E&W) lookup has been created from a Postcode Sector shapefile and the population-weighted centroids. (File Size 13 MB).Field Names – OA21CD, PCDS21CDField Types – Text, TextField Lengths – 9, 6

Dataset contains polygons corresponding to the top level (Postcode Area) of the GB Postcode Hierarchy. Thiessen polygons were generated from all records in OS OpenData Code-Point Open. Resulting coverage was dissolved up to postcode area level and then clipped to GB extent of the realm using OS OpenData Boundary-Line. Names of postcode areas were added from Wikipedia. GIS vector data. This dataset was first accessioned in the EDINA ShareGeo Open repository on 2010-07-22 and migrated to Edinburgh DataShare on 2017-02-21.

A best-fit lookup between output areas and enumeration postcode sectors as at 31 December 2011 in England and Wales. The 2011 OA to enumeration postcode sector (E&W) lookup has been created from a base file, namely the residential postcode (census enumeration only) to 2011 OA lookup. The base file was created by best-fitting postcodes to 2011 OA by plotting the postcode centroid (the point of the mean address in the postcode) into the 2011 OA. To create a 2011 OA to postcode sector lookup from the base file, the following processes were run: - postcodes were truncated to five characters (postcode sector level) from seven characters (unit postcode level). - these five character postcode sectors were grouped to form a postcode sector to OA lookup (many postcode sectors to many OA). - each unique OA was then assigned to a single postcode sector. If an OA covered more than one postcode sector, the postcode sector with most Census population falling in the OA was assigned. This gives a one OA to many postcode sectors lookup. Postcode sectors can cross administrative areas and will only be aligned within the defined postcode hierarchy. (File Size 3MB).

Please note that Deprivation Ranks are released at Lower Super Output Area/Data Zone level and are not for each individual postcode.

Suppressed postcodes in Northern Ireland

For confidentiality reasons, counts were suppressed for postcodes that had less than 10 usual residents and had only 1, 2 or 3 households in them.

The Registrar General took steps to ensure that the confidentiality of respondents was fully protected. Accordingly, all published results from the 2011 Census (including those relating to Postcodes) were subject to statistical processes to ensure that individuals could not be identified. For these postcodes, averages were taken at Postcode District level and released in a separate table, which can be found below.

Missing postcodes

These postcodes are based upon the sets of enumeration postcodes provided by the three UK census agencies. Enumeration postcodes are a subset of the complete set of live postcodes at the time of the 2011 Census. These are aggregated to create census output areas, which are themselves aggregated to create most other census geographies.

Only postcodes with at least one resident person are included. Many postcodes, such as those assigned to businesses, don't have any resident populations and so won't appear in the table.

Postcodes are quite volatile; new postcodes are created and old ones are terminated regularly. Existing/live postcodes can also change through the addition or removal of delivery points. The ONSPD records all live and terminated postcodes. Each postcode has a date of introduction and, if relevant, a date of termination. Things are complicated further because postcodes can be re-used, so a postcode can be terminated and then reappear with a new date of introduction, replacing/removing the record for the previous instance of the postcode. Postcodes that weren't current at the time of the census also won't appear in the table.

UK Postcode-level Flood Risk Data (Rivers and Sea)

Identifying Risk Areas for Flood Protection and Planning

By IBM Watson AI XPRIZE - Environment [source]

About this dataset

Welcome to the UK Postcode-level Flood Risk Dataset. This open source dataset contains detailed information on flood risk levels by postcode in the UK, allowing you to map out potential problems and plan accordingly. With this dataset, you can assess each postcode's growing risk of floods due to human land use change and climate change-related weather patterns, as well as historical occurrences specific to each area.

We pull data from organizations including Risk of Flooding from Rivers & Sea, Open Postcode Geo, Royal Mail copyright & database right (2017), National Statistics data Crown copyright & database right (2017), and Environment Agency data licensed under the Open Government Licence v3.0. The associated columns in this dataset are detailed below:

• Postcode - unique identifier for the postal code district where flood risk area is located
• FID - Unique ID for each location point
• PROB 4BAND - Flood risk level for a given postcode determined according to a four tier grade system (High, Medium, Low or Very Low)
• SUITABILITY - Suitability of location based on environment factors assessed according to OFRA criteria
• PUB_DATE - Date when data was published or last updated
• RISK FOR INSURANCE SOP - Standard Operating Procedure assigned according the Probability 4 band Risk rating
• Easting/Northing/Latitude/Longitude – Coordinates associated with a given postcode location

This data can be used by local authorities and agencies conducting flood mapping projects; insurers assessing assets at specified locations using an agreed set of methodology; advisors assessing locations for development purposes; forecasters aiding contingency planning; homeowners/commercial businesses seeking insurance cover for claims arising from flooding events etc. Ultimately we hope citizens around the world use this dataset as an important tool to predict areas exposedto potential flooding risks so that preventive measures may be taken beforehand!

How to use the dataset

This Kaggle dataset provides postcode-level flood risk data for the UK, including the flood risk level, coordinates, and other related information. This dataset is derived from Risk of Flooding from Rivers and Sea (provided by the British government) and Open Postcode Geo. It is licensed under the OGL 3.0 open government license.

In this data set you will find columns for each postcode as well as unique identifiers for a particular region (FID), an overall four band flood risk level (PROB_4BAND), whether a specific location or building is suitable or not (SUITABILITY), when it was published so you can be sure you are getting reliable up to date information (PUB_DATE), Easting/Northing which roughly measure distance eastwards/northwards of locations in meters(EASTING / NORTHING), LATITUDE & LONGITUDE that point to a precise location on google map & finally RISK_FOR_INSURANCE SOP which clearly distinguishes between sites which should generate warnings with regard to various kinds of insurance policies. This allows companies applying digital transformation solutions like hazard mapping solutions to show what risks certain locations present in relation to possible flood damage using digital technologies such as GIS systems or location intelligence tools etc., allowing organizations apply data science models or techniques like predictive analytics that may be used in decision making processes such as those taken by municipalities when signing off disaster management plans etc..

You can use this dataset for research purposes, share your findings on websites through charts & graphs to develop an educational understanding about possible hazards associated with areas that people inhabit around UK particularly at times when storm systems are localized heavily over specific regions making it most likely due causing major catastrophic event across British Isles . People living there can always access their respective postcodes very easily via our Flood Map by Postcode page here Flood Map.

Open Flood Risk by Postcode

English postcodes and the Environment Agency's risk level for the area that postcode falls within.

Fields

• postcode
• FID
• PROB_4BAND
• SUITABILITY
• PUB_DATE
• RISK_FOR_INSURANCE_SOP
• easting
• northing
• latitude
• longitude

Risk levels

Possible values for PROB_4BAND

• High
• Medium
• Low
• Very Low
• None

Methodology

The position of the postcode is determined using a point location from Open Postcode Geo. This point location places the postcode in the corresponding area within Risk of Flooding from Rivers and Sea and the risk level (PROB_4BAND) is linked to the postcode. This allows flood risk level to be looked up by postcode.

Note that properties within the postcode may have a slightly different point location and thus be located in a different area with a different risk level. Generally speaking the point location of the postcode is determined by the point location of the centremost property in that postcode.
