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.

UK Postcode Elevations

Elevation and Centroid Locations

By GetTheData [source]

About this dataset

This Open Postcode Elevation dataset contains elevation data for all UK postcodes with the exception of Northern Ireland, as these are covered by a more restrictive licence. You can use this data to map out a route's ascent or descent, giving you valuable information about that area's altitude profile. This data can also be combined with other datasets in order to explore the influence of altitude on certain stats - including whether living at higher or lower altitudes has any implications on health and wellbeing!

Our methodology involves using PostGIS to link each postcode centroid with its corresponding contour line and assigning an elevation based on that. However it's important to note some limitations - due to the fact that a single postcode may contain many buildings, their elevations could vary dramatically from one another.

Both OS Terrain 50 and ONS Postcode Directory are covered by the Open Government License for anyone interested in exploring this dataset further. So why not try searching a postcode at our Get The Data homepage to see how its elevation is calculated!

The ‘Flood risk: Postcode search tool data’ is primarily intended for use by an interactive tool (the ‘Flood risk: Postcode search tool’), but it is also published as open data. The tool is designed to be embedded in third party online media such as news websites, within relevant contexts (relating to flooding and climate change for example). The tool shows information about the flood risk within a postcode and invites users to find out more by clicking on a link which will take them to the GOV.UK service ‘Check your long-term flood risk’: https://www.gov.uk/check-long-term-flood-risk. The data is for long term risk of flooding, not floods that are expected to happen now or in the next 5 days. The risk is for the area around an address, not the address itself.
