Gefahrenhinweiskarten — synoptische Hinweisgebiete
What this layer shows
The cantons' hazard indication maps: broad-scale and mostly modelled, they show where flooding, landslide, rockfall or avalanche processes must be reckoned with, including outside the areas mapped in detail. They say nothing about intensity and do not replace a hazard map; an indication means the hazard has to be clarified for a project. Included: the cantons of AG, AI, AR, BE, BL, FR, GE, GL, GR, JU, LU, SH, SO, SZ, TG, TI, VS, ZG and ZH; cantons whose terms of use do not allow use in this app, or that do not publish the data openly, are not included. For the canton of Graubünden's data: “No warranty is given as to the correctness, accuracy, currency or completeness of the published information.”
