RTM Data – Sites

All BDRTM sites for dissemination, with validated/broadcast status. This also includes sites corresponding to the communal territory. The site is a geographical entity freely chosen by the RTM services, which is linked to only one type of phenomenon. A site is identified by a name and number. Site splitting favours a functional approach rather than a stake-based approach, by reason of the influence of phenomena. A site is therefore a subdivision of the corresponding territory for block falls to a slope comprising emitting and arrival areas. Where several starting areas can be distinguished in the same slope, e.g. separated by slopes without rock outcrops, they shall be grouped in a single site if they are close due to the possible crossing of the paths on the slope; several sites will be distinguished only in the case of a free cut (e.g. secondary valley cutting the slope) and separate operation. ATTENTION: Represented by a polygon, a site is by no means a hazard map and should not be used for this purpose.所有用于对外发布的BDRTM站点，均已完成验证与播发。此类站点亦涵盖对应行政公社管辖范围的站点。 站点为RTM业务部门自主选定的地理实体，仅与单一类型的灾害现象相关联。每个站点均通过名称与编号进行唯一标识。 考虑到灾害现象的影响特征，站点划分优先采用功能导向的方法，而非基于权属的划分方式。 因此，针对边坡块体坠落灾害的对应管辖区域，站点是其细分单元，涵盖源发区与波及区。 若同一边坡内可区分出多个源发区——例如被无岩石出露的斜坡所分隔——若这些源发区因边坡上的崩落路径可能交汇而间距较近，则应将其合并为单个站点；仅当存在独立切割（例如次生山谷切割边坡）且作业分离的情况时，方可划分多个站点。 注意：站点以多边形矢量形式表征，其绝非灾害风险图，不得用于该类用途。
