Description
Data from the DDT28 (SGREB service) updated in 2017 with the BSIG, and validated on 01/02/2018 by the business service.
Then one-off updates (last dated 23/01/2020)
This layer corresponds to flood-free areas (cf. layer N_INOND_HORSPPRI_ZINF_S_028), supplemented by flood PPR envelopes and R111-3 as PPR Flood.
It incorporates data from different scales (25 000th to 1,000ths): the final scale is therefore 25 000e and it is strongly advised not to use it below 10,000e for precision issues in certain areas of the layer.
