Port sub-division

Within port boundaries, for its own management needs, the Department uses a sub-division for ports for which it has direct management. These data are only for the 10 ports under direct management located on the Arcachon Basin. As part of the same need, each port pier is identified thus constituting a sub-division. The boundaries have no geographical value and only contribute to a better geographical identification of port infrastructure; in many cases they correspond to a historical division whose denomination is linked to the villages or so-called pre-existant places to the creation of ports.These boundaries are theoretically fully included within the boundaries of the Port Public Maritime Domain in which the Department exercises its police power. All of these areas contribute to the numbering needs of plots allocated for temporary occupations (AOT). This division has no regulatory value.在港口辖区范围内，为满足自身管理需求，主管部门针对其直接管辖的港口采用细分区划管理模式。 本次数据集仅涵盖位于阿卡雄湾（Arcachon Basin）内的10个直属管辖港口。 出于同一管理需求，每个港口码头均被单独标识，由此形成细分区划单元。 此类边界不具备实体地理意义，仅用于优化港口基础设施的地理标识工作；多数情况下，此类边界对应历史形成的区划，其命名与港口建成前便已存在的村落或相关区域直接相关。 理论上，上述边界完全纳入主管部门行使治安管辖权的港口公共海事辖区范围之内。 所有上述区域均用于满足临时占用地块（AOT）的编号管理需求。 该划分不具备任何法规约束力。
