Magic Sheet 20 Sisyphus Enarete — Level 2,3,4 (RNDT Dataset) — Version 2.0

Representation of the geo-referenced map only relating to the sheet in question, for the following three levels descritti:Livello 2: Morphological units (UM)Represent large units within which morphological traits (EM of Level 3) are grouped even different but whose predominance is characteristic and indicative of certain processes or geological phenomena.Level 3: Morphobatimetric elements (EM)Represent individual, physically distinct morphological elements, specifically associated with a precise geological process or, in certain cases, to indeterminable processes on an exclusively morphobatimetric basis. In this case, the genesis of the EM remains indefinite.Level 4: Criticality PointsRepresent one or more EMs of Level 3 which, in the opinion of the interpreter, indicate the existence of a risk, understood as a concrete possibility that, if a given event occurs, it could harm people and/or infrastructure (even if it is impossible to specify the probability and how long such an event may occur).本地理参考地图仅针对所涉单幅图幅制作，涵盖以下三级分类： 二级：地貌单元（Morphological Units，缩写UM）：指规模较大的地貌单元，内部可包含各异的三级地貌要素（EM），但以某类地貌特征占优为典型标识，可指示特定地貌过程或地质现象。 三级：地貌测深要素（Morphobatimetric Elements，缩写EM）：指独立且物理形态可区分的地貌单元，通常与明确的地质过程相关；在部分情形下，若仅通过地貌测深特征无法判定成因，则此类要素的成因仍不明确。 四级：临界风险点（Criticality Points）：指解译者认定可指示风险存在的一处或多处三级地貌要素。此处所指风险为：当特定事件发生时，可能对人员及/或基础设施造成损害的具体可能性（即便无法确定该事件的发生概率与发生时机）。
