**This dataset has been superseded. The latest version is newGeoSure Insurance Product version 8 2020.1** The newGeoSure Insurance Product (newGIP) provides the potential insurance risk due to natural ground movement at a postcode level. It incorporates the combined effects of the 6 GeoSure hazards on (low-rise) buildings: landslides, shrink-swell clays, soluble rocks, running sands, compressible ground, and collapsible deposits. The newGeoSure Insurance Product evaluates these hazards using a series of processes including statistical analyses and expert elicitation techniques to create a derived product that can be used for insurance purposes such as identifying and estimating risk and susceptibility. The newGeoSure Insurance Product is updated biannually with new releases of Ordnance Survey Code-Point® data (current version used: 2016.3) and is provided for national coverage across Great Britain (not including the Isle of Man). This product is available in a range of GIS formats including Access (*.dbf), ArcGIS (*.shp), or MapInfo (*.tab). The newGeoSure Insurance Product is produced for use at 1:50 000 scale, providing 50 m ground resolution.

The sources of the newGIP dataset are the GeoSure v7 product and Code-Point® Ordnance Survey data v2016.3. <br>Unified Hazards:<br>•The creation of the Unified Hazards layer requires the six master GeoSure layers. The six hazard layers are combined into a single unified layer using a set of weighting factors that balance the effect of each of the individual hazards. The weighting factors have been derived via an Expert Elicitation exercise. The exercise considered the combination of hazard impact and probability of occurrence.<br>•Once the six hazard layers have been reclassified, they are combined into a single layer. The total score (Total) and Geometric Mean / Arithmetic Mean ratio (GMdivAM) are then calculated. Note that when calculating GMdivAM a nominal value of 0.1 was substituted for any zero values.<br>Derived Postcode Database:<br>•The postcode centroids layer (OS CodePoint OpenData), as supplied by Ordnance Survey, is buffered using a value of 355 metres for urban postcodes and 405 meters for rural postcodes. These values take into account the 50 metres cartographic precision of the Digital Geological Map of Great Britain at the 1:50,000 scale (DiGMapGB-50) data that is used as the geological basis for the GeoSure hazard layers. The cut-off point between the urban and rural polygons (OS CodePoint with polygons dataset) was determined from the distribution of the area of postcodes and resulted in a figure of 74668.84 m2.<br>•The DPD scores are calculated by intersecting each postcode polygon with the Unified Hazards Vector Dataset and calculating the area weighted average of the individual hazard scores within each buffered postcode polygon. Each individual hazard score is then summed to give a total score. The total score is classed into 5 equal classes to produce a Class field. The classes used are Low, Low-Medium, Medium, Medium-High, High.
