LAND-deFeND

LAND-deFeND ,a new database structure able to store, organize, and manage in a single digital structure spatial information collected from various sources with different accuracy. It defines four groups of entities, namely: nature-related, human-related, geospatial-related, and information-source-related entities that collectively can describe fully the geo-hydrological hazards and their consequences.

LAND-deFeND是一种新型数据库架构，可在单一数字架构内对多源异构精度空间信息进行存储、组织与管理。该架构定义了四组实体（entities），分别为与自然相关、与人类活动相关、与地理空间相关以及与信息源相关的实体，这些实体可协同完整刻画地理水文灾害（geo-hydrological hazards）及其所造成的后果。
