Map Viewing Service (WMS) of the dataset: Flooding areas outside the regulatory zones (excluding PPR flooding and R111-3 being PPR), in Eure-et-Loir (028), at 28/04/2022

Data from the DDT28 (SGREB service) updated in 2017 with a contractor and the BSIG, and validated on 01/02/2018 by the business service, then updated on a one-off basis by the BSIG (the last one dated 22/03/2022).
This layer corresponds only to flooding areas outside the regulatory documents (excluding PPR flooding and R111-3 as PPRI).
Envelope zones of all known floods, either by modelling or by field observation.

It integrates data at different scales: the final scale is therefore the 25,000e and it is strongly advised not to use it below 10,000th for precision issues.

本数据集源自SGREB服务（SGREB service）下的DDT28数据，2017年由承包商与BSIG联合完成更新，并于2018年2月1日经业务部门验证；后续由BSIG进行过一次性更新，最近一次更新日期为2022年3月22日。
本地理图层仅涵盖法规文件规定范围外的洪涝区域，不包含PPR洪涝（PPR flooding）及归类为PPRI（PPRI）的R111-3区域。
本图层包含所有通过建模或实地观测获取的已知洪涝事件的包络区域。
本数据集整合了多源多比例尺数据，最终输出比例尺为1:25000。出于精度考量，强烈建议请勿使用低于1:10000的比例尺。
