Dataset of the historic built environment risk estimate for two counties in southern Norway

This data article presents a geospatial dataset of multi-hazard exposure and climate-based decay hazard indices for the historic built environment, enabling a relative risk estimation across three climate periods: a historical baseline (1971–2000) and two future climate periods (2031–2060 and 2061–2100). It is tested and applied for two counties in southern Norway (Agder and Innlandet). Both shapefiles contain 21 columns, as follows: Field name Type Description FID Object ID Unique identifier of the historic building Shape Geometry Point buil_no Long integer Building number according to the National Cadastre Buildings registry mun_no Long integer Municipality number CH_status Long integer Shows if the building is in the Norwegian Database for Cultural Heritage sites or not. 1 if yes; otherwise, 0 sefrak_reg Long integer Shows if the building is in the SEFRAK registry or not. 1 if yes, otherwise, 0 historic Double Historical climate decay values r2031 Double 2031 projected climate decay values r2071 Double 2031 projected climate decay values flood Double 1 if located within flood hazard area; otherwise, 0 rock_fall Double 1 if located within flood hazard area; otherwise, 0 landslides Double 1 if located within flood hazard area; otherwise, 0 snow_av Double 1 if located within flood hazard area; otherwise, 0 overgrowing Double 1 if located within flood hazard area; otherwise, 0 haz_sum Double Sum of the five binary hazard indicators (multi-hazard), as follows: flood + rock_fall + landslides + snow_av + overgrowing v_dec_hist Double Reclassified field for historical vulnerability decay, as follows: 1 (Low) if between 0-24; 2 (Medium) if between 25-48; 3 (High) if > 48 v_dec_2031 Double Reclassified field for 2031 projected vulnerability decay, as follows: 1 (Low) if between 0-24; 2 (Medium) if between 25-48; 3 (High) if > 48 v_dec_2071 Double Reclassified field for 2071 projected vulnerability decay, as follows: 1 (Low) if between 0-24; 2 (Medium) if between 25-48; 3 (High) if > 48 risk_hist Double Final risk estimate is the product between haz_sum x v_dec_hist risk_2031 Double Final risk estimate is the product between haz_sum x v_dec_2031 risk_2071 Double Final risk estimate is the product between haz_sum x v_dec_2071
