Postcode district boundaries are created and maintained by National Records of Scotland (NRS). Postcode districts are represented by the outward code (first part of a postcode). For example, if the individual postcode is EH12 7TB, then the district of that postcode is EH12. Postcodes that fall within the same district are dissolved to create postcode district boundaries. NRS publish these boundaries twice a year as part of the Scottish Postcode Directory (SPD) which should be considered the definitive source for postcode geographies in Scotland.

Postal Areas (POA)

Postal Areas (POAs) are designed to approximate postcode boundaries, as closely as possible. There is not a one-for-one correspondence between Australia Post postcodes and POAs, but these are a good starting point for comparison of Census data with other data collected using postcodes.

Census Postal Areas exclude non-mappable Australia Post postcodes such as:

• post office box postcodes
• some delivery route postcodes, which are also covered by other postcodes (a situation which often occurs in rural areas)
• some postcodes which, because of the application of the 'best fit' principle, do not get a Mesh Block allocated to them.

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-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

The Locality and Postcode Areas dataset depicts the authoritative boundaries and names of localities. A locality is an administrative area which uniquely defines the name of a place to enable street addressing. In metropolitan areas it may also be referred to as a âsuburbâ. Every locality has been defined with boundaries that do not overlap with other localities. Because of its unique name and unambiguous boundaries, a locality provides the official reference point for addressing purposes. A locality may include a town having the same name Locality Boundaries generally extend to High Water Mark and may not include uninhabitable offshore rocks and small islands. Larger named islands which are not included in this dataset will, if required for addressing or location purposes, use the official island feature name as the locality. Attributes include: The approved locality name (NAME); The Postal Code assigned by Australia Post for a locality (POSTCODE); The plan reference of the Central Plans Office plan that defined the initial locality (PLAN_REF); The Gazettal date for the proclamation first proclaiming the locality (GAZ_DATE) The Place Names Advisory Panel (formally Nomenclature Board of Tasmania) approves the Locality boundaries and names, and Postcodes have been assigned by Australia Post.

Open Postcode Geo is a postcode dataset and API optimised for geocoding applications. You can use Open Postcode Geo to geocode a dataset, geocode user input, and therefore build a proximity search.

Data is derived from the ONS (Office for National Statistics) postcode database and is free to use, subject to including attributions to ONS, OS (Ordinance Survey) and Royal Mail.

Information is also provided on a range of topics, including education, health, crime, business, etc.

Postcodes can be entered at area, district, sector, and unit level - see Postcode map for the geographical relationship between these.

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).Field Names – OA11CD, PCDS11CD

Metropolitan postcode regions have been produced in the EU together with the cities of Helsinki, Espoo and Vantaa. The documentation contains detailed territorial boundaries and information on postal codes and places of business.

The boundaries of postal codes have been produced largely on the basis of the municipalities’ own boundaries and are therefore compatible with the municipalities’ own postal code area boundaries. The accuracy of the harmonised material varies slightly from one municipality to another, due to baseline data and maintenance practices. The postcode areas are not linked to the administrative divisions and are therefore located in several municipalities. The file contains information on postal codes and post offices. In addition, the indicative names of the regions have been added to the file from Statistics Finland’s open postal code domain material.

For 2019, there will also be material cut along the coastline. This is better suited to visualisations that do not want to include marine areas. The cut has been carried out with the marine material of the Seutu map.

The materials have been completed in the first half of each year.

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.

The topographic map 1 : 250,000 - Issue with postcodes - gives an overview of all postcodes and postcode zone borders in the state of Brandenburg. In addition, the administrative boundaries from the municipal to the state border are presented on a topographical basis. This map is available in plano as a plot.

Postcode area boundaries for Tasmania. Postcode area boundaries for Tasmania.

Postcode sector boundaries are created and maintained by National Records of Scotland (NRS). Postcode districts are represented by the outward code (first part of a postcode) plus the first character of the inward code. For example, if the individual postcode is EH12 7TB, then the sector of that postcode is EH12 7. Postcodes that fall within the same sector are dissolved to create postcode sector boundaries. NRS publish these boundaries twice a year as part of the Scottish Postcode Directory (SPD) which should be considered the definitive source for postcode geographies in Scotland.
