Tiivistelmä: The historic flood maps dataset (in Finnish Havaitut tulvat) includes data on detected (observed) floods indicating areas that have been covered by observed floods in some point of time. The historic flood maps can also be produced near real time using satellite images. The observed flood covered area has been outlined based on a field visits (marking or photographing the border area of the flood on site) or outlining has been done using remote sensing data (aerial photographs or satellite images). The border data can later be combined with information on water levels on marked water level measuring stations. The historic flood maps dataset consists of yearly datasets covering whole Finland. One map layer consists of the floods during the same year, but generally only one flood area is digitized from the same area per year. The dataset includes also the outline of the flooded area detected from the field or interpreted from the satellite images. Additional information on flood mapping is available on the flood mapping webpages http://www.ymparisto.fi/default.asp?contentid=415135&lan=fi&clan=en and in SYKE’s publication “guidelines for flood hazard mapping on a coarse scale” (in Finnish only) (http://www.ymparisto.fi/default.asp?contentid=175706&lan=fi (available in Finnish only).

Käyttötarkoitus: The flood maps can be used to support flood-risk management, to draw up flood-risk management plans, to plan against flood damages, in land use planning, to provide information on floods, in rescue operations and in determining the lowest suitable construction elevation in order to avoid flood-risks.

Laatutiedot
Historiatiedot: The historic flood map areas were outlined based on field surveys or remote sensing data. When using the dataset for planning or management purposes, the uncertainties in the source material, base material and its implications to the accuracy of the flood map need to be taken into account. As a rule the dataset does not have high enough accuracy to make any assumptions on individual buildings.
