Hva dette ikke sier
Gjengitt ordrett fra seksjonens warnings-felt, slik API-et returnerer det. Vi oversetter dem ikke: en oversettelse ville vist noe annet enn det svaret ditt faktisk inneholder.
- Estimate, not Kartverket's storm-surge map (stormflo aktsomhetskart) and not a flood assessment of the plot: a modelled still-water margin from public height and sea-level data.
- freeboard_<T>y_<year>_m = ground height at the address point (Kartverket Høydedata, NN2000; ground_height_source says which terrain model answered, dtm1 where the 1 m model covers it) minus the still-water level of the T-year storm surge in that year. Negative means the water stands above the ground. Return levels today and land uplift come from Kartverket's tide API, sampled once per 2 km of coast (the API answers per tide zone, so neighbouring buildings share one answer). The 2100 level adds Kartverket's projected relative change between its 200-year polygons today and in 2100 at the nearest stretch of coast (relative_sea_level_change_2100_m; uplift is already in it, absolute_sea_level_rise_2100_m adds it back for transparency). 2050 interpolates that change linearly from 2020 (reference_year), which overstates an accelerating rise slightly, so 2050 errs low. The same change is applied to the 20- and 1000-year levels.
- Still water only: waves, wind set-up, river flow and rain are not included, and the address point is not the lowest door or the basement. first_reaching_scenario reads today, 2050, 2100 in turn and within each year the 20-, 200- and 1000-year event; null means none of the nine reaches the ground, or the inputs are missing (scenarios_evaluated says how many could be computed). A future scenario is null, not today's value, when the sea-level change is unknown.
- Only addresses within 500 m of Kartverket's largest storm-surge extent are scored; inland addresses have no row. in_storm_surge_200y_present_polygon and polygon_agrees are null outside Kartverket's model coverage. The validation block is agreement with Kartverket's own 200-year polygons over all scored addresses: both use terrain heights and similar levels, so it checks consistency, not truth on the ground.
